A thank-you for your botanic garden volunteers: a photo of the glasshouse in the morning light as a jigsaw, with your note at the end

Written by the team behind Puzzlify. Puzzlify is our product, so weigh what follows with that in mind. We've tried to make this useful even if you never use it. We're not affiliated with any botanic garden, arboretum, university garden, herbarium, friends group, garden trust, plant society, conservation charity, council parks service, heritage funder, sponsor, school or community organisation. Nothing here is legal, plant health, biosecurity, toxic plants, glasshouse safety, tools, work at height, collections, photography permission, health and safety, first aid, employment, safeguarding, copyright or data protection advice; check your own group's and the garden's guidance on gifts, photos, plants, cuttings, seeds, glasshouses, tools, children and people's details.

It's twenty to nine on a bright Thursday morning in October, and a retired pharmacist called Helen is signing in at the volunteers' gate of a botanic garden. The public won't be let in until ten. Through the railings, the lawns are silver with dew, the big Victorian glasshouse is steaming gently in the low sun, and a gardener in a green fleece is wheeling a barrow of leaves past the lily pond. Somewhere behind the rock garden, a robin is singing as if it owns the place.

Helen has her lanyard, her secateurs in a holster she's only allowed to use in the propagation yard, a notebook and a packed lunch. On Thursdays she works with the propagation team: potting on seedlings, labelling trays, sowing seed collected in the garden under the curators' supervision, and keeping careful records so that every plant can be traced back to where it came from. On Saturdays, she guides. She knows the age of the cedar by the lake, the story of the plant hunter who brought back the rhododendrons, which tree in the arboretum is the rarest, and how to explain photosynthesis to a group of seven-year-olds in under two minutes.

Helen has been a botanic garden volunteer for twelve years. She came to a talk on medicinal plants just after she retired, asked a question nobody else had thought of, and was signed up by the volunteer coordinator before she reached the door. The garden has around two hundred volunteers and a small paid team of curators, horticulturists, educators and scientists. There's a retired teacher called Peter who leads the school sessions; a quiet man called Sunil who has spent nine years mounting, labelling and databasing specimens in the herbarium; a pair of sisters who run the plant sale and the friends' shop; a young graduate who records the bees, butterflies and lichens; a volunteer who welcomes visitors at the gate in every weather; and a friends group committee that raises money, runs the talks programme, publishes the newsletter and quietly funds things the garden couldn't otherwise afford, from a new bench to a whole glasshouse restoration.

By eleven, there'll be pushchairs on the paths, a group of art students sketching in the palm house, a couple who got engaged under the magnolia forty years ago walking slowly arm in arm, and a school party being shown how a pitcher plant catches its dinner. By four, the leaves will be raked, the trays watered, the herbarium sheets put away in their cabinets and the gate locked again. Hardly anyone will know who potted the seedlings, mounted the specimens or wrote the label by the cedar. That is how most garden volunteers like it.

If you know someone like Helen, or Peter, or Sunil in the herbarium, this is for you. It's about thanking the people who give their time to a botanic garden or arboretum: the guides, the propagation and horticulture volunteers, the herbarium and library helpers, the education team, the friends group and its committee, the welcome volunteers, the recorders and the people at home who let them go every week. It's about words first, a few practical rules, photos that work and a simple idea we make: a private digital jigsaw of a photo they love, with your note appearing when the last piece clicks in.

Who we mean

Botanic gardens and arboretums come in many shapes. Some are large national institutions with research and conservation programmes; some belong to universities; some are run by councils, trusts or charities; some are small community gardens with a remarkable collection. Almost all of them rely on volunteers and many have a friends group that supports them. When we say "botanic garden volunteers", we mean the people in and around those groups:

the guides and docents who lead tours, explain the collections and answer the same questions with patience every weekend;
the horticulture volunteers who weed, rake, mulch, deadhead and help the gardeners in the beds and borders, under supervision;
the propagation volunteers who sow, pot on, label and record plants in the nursery, following the garden's rules on provenance and plant health;
the herbarium and library volunteers who mount, label, digitise and database specimens, books, archives and seed records;
the education volunteers who help with school sessions, family trails, holiday activities and adult courses;
the welcome and visitor volunteers at the gate, the glasshouse door and the information desk;
the recorders and citizen scientists who survey birds, bees, butterflies, fungi and lichens, or record flowering dates over many years;
the friends group committee, including the chair, the secretary, the treasurer and the membership secretary, who raise money and run the talks, trips and newsletter;
the plant sale and shop volunteers who turn surplus plants and good will into funds;
the photographers, illustrators, writers and social media volunteers who tell the story;
the founders and the long-serving friends who remember what the garden was like before the restoration.

Some gardens have a handful of volunteers who meet once a week. Others have hundreds and a full-time volunteer manager. Everything here works either way.

Words first

The most important part of any thank-you is what you say. Garden volunteers rarely hear specific praise, because the best garden work looks as if it happened by itself. Nobody says "beautifully weeded border". So be specific:

name the job: "the seedlings in the propagation yard", "the specimens in the herbarium", "the Saturday tours", "the plant sale every May";
name a moment: the day the titan arum flowered, the school session when a shy child asked to hold the seed pod, the spring the restored glasshouse reopened;
name what it meant: your mother's favourite bench by the rose garden, your first date under the cedar, the walk that got you through a difficult year;
name the years: "twelve years of Thursdays" means more than "thank you for all you do".

If you're thanking a whole group, try to name the people who never get named. The membership secretary, the person who edits the newsletter, the volunteer who counts the plant sale takings, the one who makes the tea for the herbarium team. They're the ones who keep a garden's volunteer life going.

A sentence like "the garden wouldn't be the same without you" can sound like a cliché, but for many volunteers it's true. If it is, say it, and then say why.

Who it suits

A photo jigsaw with a note works best for someone who:

enjoys a small puzzle on a phone or tablet, or has grandchildren who'll help;
has a strong feeling for a particular tree, bed, glasshouse or view;
is stepping down, retiring from a role or celebrating a long service milestone;
has moved away and misses the garden in its seasons;
has a partner or family who'd like to say thank you for all the days they gave the garden.

It's less suitable for someone who doesn't use a phone or a computer at all, in which case a printed card or a framed photo may be better, or someone who would feel uncomfortable being singled out. For them, a quiet thank-you in person may be best.

Gifts, plants and good manners

A few practical rules before you send anything:

The garden and the collections come first. Never take a photo, hand over a gift or stop a volunteer while they're leading a group, working in a bed, handling specimens or helping a visitor. Wait until they're on a break or signed out.
Never take cuttings, seeds or plants. Botanic garden collections are often rare, documented and part of conservation programmes. Taking material without permission is theft and can harm research. If you'd like a plant, buy one from the garden's plant sale.
Plants as gifts need care. A potted plant can be a lovely gift, but some volunteers already have more than enough, some plants are toxic to pets or children, and moving plants between gardens can spread pests and diseases. Buy from a reputable nursery or the garden's own sale, and never pass on plants or soil from the garden's beds.
Glasshouses can be hot, humid and slippery. Stay on the public paths, don't touch plants, don't climb to reach a better angle, and keep away from heating pipes, vents and watering systems.
Tools and machinery are for trained people. Secateurs, saws, mowers, ladders and tree work are covered by the garden's own training and risk assessments, never for a quick photo or a favour.
Paid staff and gift rules. Curators, gardeners, scientists and educators are usually paid staff, and many institutions have rules about gifts and hospitality. Keep anything for paid staff small and personal, or thank them through a card to the team, and check with the volunteer manager if you're not sure.
The group's money is the group's. If you'd like to support the garden, join the friends group or donate directly. Don't use friends group funds for a personal thank-you to a single volunteer unless the committee agrees. A personal gift from you is a different thing, and a modest one is fine.
Herbarium and archives. Specimens, archives and seed collections are fragile and sometimes restricted. Never photograph them without permission, never handle them, and never share images of unpublished records or rare plant locations.
Rare plant locations. If a volunteer surveys rare wild plants or orchids outside the garden, never share the location in a photo or a note. Collectors do use that information.
Children. If the volunteer helps with school groups or family activities, don't photograph the children, and don't single out young volunteers publicly without their parents' and the garden's agreement.
Cash and people's details. Keep the plant sale cash box, the till, the membership list, the volunteers' rota, the phone numbers and the friends group's bank details out of everything you photograph or send.

When to send it

Good moments to thank a botanic garden volunteer:

at the end of the season, when the borders are cut back, the leaves are raked and the garden goes quiet for the winter;
after a big event: a plant sale, an open day, a festival of light, a flower show or a famous plant's flowering;
after a restoration milestone, such as a glasshouse or a historic garden reopening;
when a volunteer steps down from a role they held for years, or retires from guiding;
on a volunteering anniversary, or during national volunteers' week;
at the friends group AGM, when the committee thanks everyone in the room;
on a birthday, if you know them well;
at Christmas, when the garden's winter lights or wreath workshops are on;
in memory of a volunteer who has died, with their family's agreement.

There's no wrong time to say thank you, but late October is a good one. The clocks are going back, the leaves are turning in the arboretum, and the volunteers are about to spend the winter sowing seed, mounting specimens and planning next year's talks.

Why a jigsaw can fit

A botanic garden is built from thousands of small pieces: every bed, every label, every pot, every specimen sheet, every seed packet, every record. Nothing happens all at once. A seed sown this winter might not flower for years, and a tree planted today will be enjoyed by people not yet born. A jigsaw, slowly assembled piece by piece, with a note that appears when the last piece goes in, echoes that patience. It's also something to do on a dark winter evening, when the garden closes early and spring feels a long way off.

It's private, it's small, and it doesn't add to the clutter in someone's house, which matters to people whose homes are already full of seed trays, plant books and pressed flowers. And unlike a framed print, it can be sent from anywhere: from the family who moved away, from the grandchild studying botany, from the former guide who now lives abroad.

For the guides

Guides turn a collection into a story. They know which plant hunter brought back the tree by the lake, why the cactus house smells of warm sand, and how to make a fern interesting to a bored teenager. A note to a guide might mention a tour you went on, the fact you still remember, or the way they spotted that your child was lagging behind and asked them a question. A photo of the guide's favourite view, the great glasshouse in morning light or the big cedar on the lawn suits them.

For the propagation and horticulture volunteers

The weeders, rakers, mulchers and potters-on do the work everyone sees and no one notices. A note might mention a particular border, the seedlings they potted that became the spring display, or the number of winters they spent in the propagation yard with cold fingers. A photo of neat trays of seedlings with their labels, or a border at its best in midsummer, suits them.

For the herbarium and library volunteers

Herbarium volunteers work in quiet rooms far from the crowds, mounting pressed plants on archival paper, writing labels in careful hands, databasing records and helping to make collections available to scientists around the world. A note might mention the thousands of sheets they've mounted, the specimen collected two hundred years ago that they helped digitise, or their patience with fiddly glue and tweezers. A photo of something they're allowed to share, such as a public display, a pressed flower from the garden's own exhibition or the herbarium building's door, suits them. Never photograph the specimens or records themselves without the garden's permission.

For the education volunteers

Education volunteers help children smell mint, find seeds in a pod, spot a bee and understand why plants matter. A note might mention the trail they designed, the holiday activity your child still talks about, or the patience it takes to keep thirty children on the path. A photo of an empty classroom garden, the pond-dipping platform with nobody there, or a sunflower bed against a blue sky suits them. Never use a photo of the children.

For the friends group and the committee

The friends group committee carries the paperwork, the insurance, the talks programme, the trips, the newsletter, the membership list and the fundraising. Their work pays for benches, plaques, plant labels, bursaries and sometimes whole restoration projects. A note to a chair, a treasurer or a membership secretary might mention the appeal that bought a new glasshouse, the talks programme that ran for twenty years, or the accounts done perfectly every year. A photo of something the friends group funded, such as a restored bench, a new path or the reopened glasshouse, suits them.

For the welcome and plant sale volunteers

The welcome volunteers greet everyone at the gate, in wind and rain, and point the way to the toilets, the café and the famous tree. The plant sale and shop volunteers turn surplus plants into funds, one pot at a time. A note might mention the smile at the gate that made your first visit, or the plant you bought at the sale that's still flowering in your garden. A photo of the gate on a spring morning, or rows of plants on sale tables before the doors open, suits them.

For the recorders and citizen scientists

Recorders keep the long view: the first flowering of the snowdrops each year, the bees on the lavender, the fungi in the arboretum, the lichens on the old walls. Their records help scientists understand climate and change. A note might mention the years of records, the rare moth they found, or the walk when they showed you how to tell one lichen from another. A close-up of lichen on a stone wall, a bee on a flower or the arboretum in autumn colour suits them.

If you live with a garden volunteer

Partners and families give up a lot: the Thursdays, the Saturdays, the evenings at talks, the soil on the car mats, the seed trays on every windowsill. If you live with a garden volunteer, a jigsaw from you can say something they might not hear from anyone else: "Thank you for all the Thursdays. I know what that garden means to you, and I'm proud of you." A photo of them by their favourite tree, taken with their permission, or the bench where you sat together, suits this.

When a long-serving volunteer steps down

When someone leaves after many years, the garden or the friends group often gives them a card, a plant or a certificate. A jigsaw from the group can sit alongside that. Pick a photo that sums up their years: the border they weeded, the glasshouse where they guided, the tree they loved. Ask everyone to add a line to the note, or keep it short and let the card carry the longer messages.

In memory of a volunteer

Many gardens have memorial benches or dedicated trees. If a volunteer has died, a jigsaw can be a gentle way for their family or the group to remember them, but only with the family's agreement. Choose a photo they loved, avoid anything that might upset, leave the leaderboard off, and keep the note simple: "In memory of Joan, who guided in the palm house for fifteen years."

For garden volunteers elsewhere

Most of what we've written fits gardens in the UK and Ireland, where many towns and universities have botanic gardens, arboretums and friends groups. But botanic garden volunteers are everywhere:

in the US and Canada, where docents, horticulture volunteers and friends organisations support public gardens, arboretums and conservatories;
in Australia and New Zealand, where volunteer guides, herbarium helpers and friends groups support botanic gardens in every state and region;
in South Africa, India, Singapore and many other countries with great gardens and active friends groups;
across Europe, where historic botanic gardens, many linked to universities, rely on volunteers and friends societies.

The rules about gifts, photos, collections and plant material vary. Check your own garden's guidance, and keep the thank-you personal and modest.

The best photos for a botanic garden thank-you are often the quiet ones, taken in the morning, in the late afternoon or out of season, from the public paths, with no people in them at all. Some ideas:

the glasshouse in morning light, steam on the panes and the lawn in front;
the big cedar, oak or redwood on the lawn, with a bench beneath it;
the arboretum in autumn colour, a path disappearing through gold and red;
the lily pond with the reflections of the trees;
a border at its best in midsummer, or frosted seed heads in winter;
neat trays of seedlings with their labels in the propagation yard, with permission;
a close-up of a single flower, a seed pod, a fern unfurling or lichen on a wall;
the garden gate on a spring morning, with blossom over it.

Things never to photograph, or to keep out of the frame:

visitors, staff, volunteers and anyone's face, unless they've clearly agreed;
children and young people, at any time, including on school sessions and family trails, even from behind;
anyone up a ladder, using machinery or doing tree work;
herbarium specimens, archives, seed bank stores and research areas, unless the garden has agreed;
labels, maps or anything that reveals the location of rare or protected plants in the wild;
areas closed to the public, behind ropes, or anywhere you'd have to leave the path to reach;
the plant sale cash box, the till, the keys and anything to do with security;
the membership list, the volunteers' rota, the sign-in sheet and any message group with names and numbers;
other people's names on memorial benches or plaques, unless their families have agreed;
anything that might upset someone, such as a photo of a volunteer who has since died, unless their family has agreed.

If the photo has people in it, ask them first. A photo with no people at all, just the glasshouse, the tree, the border or the flower, is often the easiest and best choice.

Getting the JPG right

Puzzlify works from a JPG. Most phone photos are already JPGs, or can be saved as one. A few practical tips:

morning and late afternoon light is softer than midday sun, which can wash out flowers and make glasshouse panes glare;
inside a glasshouse, wait a minute for your lens to stop misting up, and wipe it gently if it does;
with a bright sky behind a tree or glasshouse, tap on the subject to set the exposure, then slide the brightness down a little so the sky doesn't turn white;
bright reds, magentas and yellows can clip and lose detail on phone cameras, so check the petals still have texture before you upload;
leaves, flowers, ironwork, panes and bark make wonderful puzzles, because every piece has a little detail;
large areas of plain sky, smooth lawn or still water are tricky, so crop them or pick fewer pieces;
landscape images usually make the most comfortable puzzles on a phone turned sideways;
if your phone saves photos in another format, such as HEIC, change the camera setting to "most compatible" or export a copy as JPG;
remove location data from the photo before you upload it, especially if it was taken at home or near a rare plant. On most phones, you can switch it off in the share options or the camera settings.

Privacy and an optional PIN

The puzzle is private: it's shared as a link, not posted on a public board. You can add an optional PIN so that only someone who knows it can open the puzzle, which is useful if you're sending it to the friends group's email list. Even so, treat the photo as if it might be forwarded, and keep visitors, children, staff, specimens, rare plant locations, security features and anyone's details out of it. Puzzlify doesn't use your photos to train AI or share them with third parties.

Say it's from you

Volunteers and friends groups get a lot of unexpected messages, from fake invoices to "your membership has expired" scams, and many volunteers are rightly wary of unexpected links. Say who it's from and what it is in the message itself: "This is a little jigsaw of the glasshouse where you guide, with a note at the end. It's from me, and it's safe to open." For someone who doesn't use email much, print the link as a QR code inside a card.

Piece counts

Pieces	Photo idea	Best for
24	a single flower or seed pod, close up	a quick solve, or a first puzzle
48	the big cedar on the lawn with a bench beneath it	one clear subject, a relaxed solve
80	trays of labelled seedlings in the propagation yard	a busier image with lots of detail
130	the glasshouse in the morning light with the lawn in front	a detailed photo for a keen puzzler
252	the arboretum in full autumn colour	a long, slow solve for a long-serving volunteer

If you're not sure, 48 or 80 pieces suits most people on a phone. Plain sky, smooth lawn and still water get tricky at high piece counts, so start lower if the image has large areas of one colour.

How to send it

Upload the photo, pick a piece count, write your note and preview it. When you're happy, publish the link and send it by email or message, print the link or a QR code inside a card, or ask the volunteer coordinator or the friends group secretary to pass it on. Start at Puzzlify's photo puzzle maker.

If you're sending one puzzle to a whole volunteer team, the optional leaderboard lets everyone see who finished first. Some teams enjoy the rivalry, a little like the friendly competition over who can identify a tree from a single leaf; others would rather solve it quietly. For a puzzle sent to one person, or after a bereavement, leave it off.

Note examples

"To Helen: twelve years of Thursdays, thousands of seedlings and one very patient explanation of photosynthesis. Thank you."
"To Peter: thank you for the school trail my son still talks about, and for finding him a seed pod to hold."
"To Sunil: nine years in the herbarium and every label perfect. Thank you for the quiet work."
"To the friends committee: one glasshouse appeal, twenty years of talks and not a penny out of place. Thank you."
"To my husband: thank you for the seed trays on every windowsill and the best garden in the city."

(Change the names, and keep anything personal or identifying out of a puzzle that may be shared.)

Honest pricing

Making and previewing a puzzle is free in your browser. You only pay when you publish the link to send it: one credit is EUR 3.99, three credits are EUR 8.99, and Plus is EUR 14.99 a year for ten credits, which can make sense if you want to thank the guides, the propagation team and the herbarium volunteers separately. The person you send it to doesn't need an account or an app; they just open the link in a browser.

This is a digital jigsaw you play on a screen. It isn't a cardboard puzzle in the post, a printed product, a plant, a raffle prize or a public puzzle board, and it isn't connected to any garden, arboretum, herbarium, friends group, council or charity. It's also not puzzlify.io (a chess site), Puzzlit, Puzzly or Puzzify, which are different things.

Ideas that are not a puzzle

Honestly, some of the best thank-yous for botanic garden volunteers cost nothing at all:

a handwritten card, handed over at the volunteers' gate or left with the volunteer coordinator to pass on;
a thank-you in the friends group newsletter, the garden's blog or the local paper, naming the guides, the propagation team, the herbarium volunteers and the welcome team as well as the committee;
nominating a volunteer or the group for a local volunteering, heritage or environment award, if your area has one;
joining the friends group, paying the membership, or sponsoring a bench or a tree if the garden runs a scheme;
offering your time: a morning at the plant sale, help with an open day, or joining as a volunteer properly through the garden's own process and induction;
visiting, bringing friends, buying a plant from the sale and a coffee from the café, because a busy garden is a funded garden;
telling a guide afterwards which fact you'll remember, which every guide treasures;
a tin of good biscuits for the volunteers' room, which never fails.

If a photo puzzle feels right as well, choose the glasshouse in the morning light, the big cedar, a border at its best or the arboretum in autumn, take it from the public paths, keep visitors, faces, children, staff, specimens, rare plant locations, cash and anyone's details out of the frame, pick a piece count that suits them, and write the note in your own words. You can make a free preview here and decide later whether to send it.

Whatever you send, the most important part is the sentence that sounds like you, written to the person who potted the seedlings with cold fingers, mounted the specimens one by one and led the tour in the rain, so that next spring, when the magnolia opens and the first school party crowds round the pitcher plants, the garden will be ready, labelled and alive, waiting for someone to notice it.
