A botanical garden is a pattern archive that rearranges itself every few weeks. Come in March and you get bare structure and bud scales; come in July and you get hanging racemes, seedheads and a colour palette that shifts by the hour.

For anyone building a surface pattern collection, that variety is the point. The ten gardens below each offer a distinct set of plant forms — radial, trailing, spiky, cushioned — along with the architectural shapes that frame them. Take a camera, a sketchbook if you use one, and a clear idea of what your collection is still missing.

Kew Gardens, London

Kew earns its reputation. The Palm House gives you fronds at eye level and above, plus a geometry of white-painted iron that is almost a pattern in itself. Shoot into the light and the ribs read as line work rather than foliage.

Then head for the Waterlily House. Victoria amazonica pads are circular with a single notch, ribbed underneath and turned up at the rim — a radial motif that is ready to draw. A phone camera is enough; you are capturing structure, not a postcard. The Temperate House adds repetition of glass panes, and the order beds show plants grouped by family in strict geometric beds, useful if you need a trellis or coordinate backdrop.

Royal Botanic Garden Edinburgh

Edinburgh's garden sits on a slope at Inverleith, so you get layered silhouettes and long views between planting. The fern house is the reason to come: filigree fronds, tightly coiled croziers, and the soft fur of tree fern trunks in deep shade.

Climb to the rock garden and alpine house for the opposite scale. Saxifrage rosettes, sempervivums, tight cushions and grey-green foliage all work as small motifs, where the shape's weight matters more than fine detail. Photograph them close, then again from half a metre back, and compare which version still reads clearly.

National Botanic Garden of Wales, Carmarthenshire

The Great Glasshouse is a single curved roof set into a hillside, and it is worth the trip for the building alone. Inside, the planting leans towards Mediterranean-climate species: silver leaves, woolly textures, spiky agave and aloe, and strong architectural forms that hold their shape against a plain ground.

Outside, the wider estate keeps wildflower meadows. Yellow rattle, ox-eye daisy and knapweed give wiry stems, hazy colour and seedheads — material for scattered, delicate repeats rather than tidy borders. Compare the two on the same visit and you have a collection's worth of contrast.

Bodnant Garden and Mount Stewart: Clipped and Hanging Forms

Bodnant Garden, Conwy

Late May brings the laburnum arch: rows of hanging yellow racemes creating a natural drop repeat, with a tunnel of shadow behind them. Elsewhere there are terraces, a pinetum where cones carry spiralling scales, and the Welsh hills beyond, which give you layered silhouettes for background elements.

Mount Stewart, County Down

Clipped evergreens, topiary and dense hedging, plus a Mediterranean garden of silver and grey foliage. If your collection needs structure rather than flourish, study how one shape repeats, how shadows fall between the forms, and how a hedge line reads as a stripe across a page.

Trebah and Inverewe: The Subtropical Edge

Trebah Garden, Cornwall

Tree ferns, gunnera with its enormous rhubarb-like leaves and odd coral-shaped flower spikes, and hydrangeas crowding the paths. The garden runs down a valley to the Helford, so light arrives filtered — ideal for soft, overlapping colour rather than hard contrast.

Inverewe, Wester Ross

Shelter belts allow tender species to grow far further north than you would expect, which creates strong pairings: lichen on stone beside fleshy rosettes, blue poppies against wind-shaped trees. Study the edges, where foliage meets rock and grey turns green. Those transitions make good border motifs.

Westonbirt, Sheffield and Hestercombe: Three Ways to Read a Season

• Westonbirt Arboretum, Gloucestershire: autumn colour, five-lobed acer leaves, bark patterns, and leaf litter as a ground texture. Arrive early; low sun makes the canopy glow.
• Sheffield Botanical Gardens: curvilinear glass pavilions and a site divided into distinct themed areas, which lets you test how one motif set behaves across several palettes.
• Hestercombe, Somerset: formal parterre geometry, gravel, stone and tight lines — the place to go when you need a grid or repeat structure rather than a single leaf.

From Camera Roll to Repeat

A photograph records a plant. A sketch records the decision you made about it.

Most garden photos never become motifs because they were taken without a job in mind. Try this sequence instead.

1. Photograph one thing at a time. A single leaf against sky, a single seedhead against gravel. Cluttered frames are hard to translate.
2. Group by form, not species. Trailing, spiky, radial, cushioned. Your collection will feel coherent if the shapes agree, even when the plants do not.
3. Reduce each image to a silhouette. Trace the outline, fill it black, and see whether it still interests you. If it does not, no amount of colour will save it.
4. Test at thumbnail size. Shrink the motif to two centimetres across. Detail disappears; shape and spacing remain.
5. Build the palette from the garden, not from auto-enhance. Pull colour from shaded stems and dry seedheads as well as flowers, and you avoid the usual bright botanical default.
6. Repeat the visit in another season. The same border in June and October gives you two collections' worth of material, and the contrast between them is often the strongest idea you will have.

Two practical notes before you go. Overcast days give even light and easier colour matching, while backlighting gives you clean silhouettes; use both deliberately. And check each garden's photography policy at the gate — most welcome personal cameras, but tripods, drones and commercial shoots are often restricted. If you plan to sell work derived from a specific planting scheme, it is worth asking the garden directly rather than assuming.
