Seasonal Botanical Art: What to Forage and Press in Each Season

Botanical art begins long before a brush touches paper. It begins with a walk, a pocket, and a decision about which stem to take. Anyone who presses plants learns quickly that the calendar matters as much as technique. A violet gathered in April and a maple leaf gathered in October ask entirely different things of you: the tissue is different, the water content is different, and so is the colour that survives the press.

What follows is a working year — what to look for in each season, what presses beautifully, what refuses to behave, and how to handle each harvest so the material is still worth using in January.

Spring: Tender Growth and Short-Lived Blossoms

Spring material is thin, watery and quick to spoil. The window for a violet, a cherry petal or an unfurling fern is measured in days, and the plants are full of water that has nowhere to go once they are between paper. Press them in thin layers, change the blotting paper daily for the first three days, and expect a higher failure rate than you would accept in summer.

What to look for: violets and forget-me-nots in short grass, honesty in flower before the seed pods form, cow parsley and wild garlic along hedgerows, apple and cherry blossom, late tulip petals, fern fiddleheads where they grow thickly, hellebore and dicentra from the garden.

Take the flower apart

A whole cherry blossom pressed in a single lump goes brown; single petals, laid separately with a small gap between them, dry into something you can use. The same is true of dicentra and honeysuckle. Separate the parts on the first day, while the plant is still turgid and easy to handle. Fiddleheads need their stems split lengthways with a sharp blade, or the water in the stem will darken and rot.

Spring is also the season to press green — young birch leaves, beech in its first flush, the pale new growth of ivy. They hold their colour well if pressed quickly; older leaves of the same species come out darker and less useful.

Summer: Petals, Grasses and Working Fast

Heat changes the rules. Material picked at noon on a warm day may be limp before you reach home, and limp material presses badly — it wrinkles, folds over on itself and loses the shape you wanted. Pick in mid-morning, once the dew has dried but before the sun is high, and carry a flat box rather than a bag so nothing gets crushed.

Summer is generous: cosmos, cornflower, nigella, lavender, scabious, clover, marigold, meadowsweet, the first roses, poppy petals in their brief prime. Grasses are at their best now too — pick the seed heads while they are still supple and before they shatter, and arrange them in the press exactly as you want them, because they will not move afterwards without breaking.

The pocket press

Some summer flowers collapse within minutes of picking. Poppy petals are the classic case, and cornflower is not far behind. A small field press — two boards, blotting paper, a couple of elastic bands — solves this: press the petals on the spot, carry them home flat, and transfer them to the main press later. It is the most useful piece of equipment you can own for summer foraging.

Thin summer petals dry in three to seven days and overcook quickly, so check them early. Whites and pale pinks are the least stable colours in the press and brown at the edges first; change their paper more often than everything else.

Autumn: Seed Heads, Skeletons and Colour That Stays

Autumn is the season for structure. Leaves have stopped growing and started toughening, seed heads have dried on the plant rather than in the press, and much of what you gather will still look like itself a year from now.

Gather leaves when they have turned but are still slightly pliable — maple, beech, oak, vine, ginkgo. A leaf that is already crisp will crack along the veins; one that is still damp will go mouldy. Leaves picked after rain need blotting dry first. Tannin-rich leaves stain the blotting paper, which is harmless but worth knowing if you are pressing onto a sheet you care about.

What autumn does better than any other season

• Honesty (Lunaria) — the papery, translucent seed heads left once the outer valves fall away are among the most rewarding things to press.
• Nigella and poppy pods — small ones flatten in a week; larger poppy heads need slicing in half.
• Allium heads — press whole and face down, and accept that they will become a star rather than a sphere.
• Hydrangea — press the florets once they have turned papery on the plant, not while they are still fleshy.
• Rosehips and small berries — halve them first, or they rot and mark everything around them.
• Grasses and small teasels — these press; large teasel heads belong in a drying jar instead.

This is also the season to be honest about what will not work. Succulent leaves, thick twigs, cones and anything with a woody core are better dried upright in a jar than flattened between boards.

Winter: Evergreens, Bark and Borrowed Structure

Winter pressing is largely about silhouette. With little in flower, the interest lies in the outline of a leaf, the curve of a twig, the pattern of a lichen. Ivy, box, holly, yew, cedar and bay all press well, though evergreens are resinous and slow, often taking four weeks or more. Change their paper less often, but do check for damp.

Bark is best taken from fallen branches rather than living trees. Peel a strip from wood that is already down and press it under heavy weight, because it will curl as it dries. Thin birch bark presses almost flat; thicker bark is better used as texture than as a specimen.

Late winter brings the first snowdrops, hellebore, winter honeysuckle and witch hazel. These are leathery and slow, and they discolour if rushed: press them, forget them for a month, and they will reward you. It is also the time to deal with what you missed in autumn — the last hydrangea, standing grasses, dry umbellifers in an uncut meadow.

Five Habits That Apply in Every Season

1. Press the same day. Every hour between picking and pressing costs colour. If you cannot press immediately, keep the material in a sealed box in the refrigerator — it will hold for a day, not longer.
2. Use blotting paper, not newspaper. Newsprint transfers, and it holds moisture unevenly. Two sheets above and two below, replaced every few days in the first week.
3. Weight matters more than people expect. A stack of heavy books, a board with weights, or a proper screw press — but nothing less than a few kilos, spread evenly.
4. Label as you go. Species if you know it, place, date. Six months later you will not remember which meadow the grass came from.
5. Take sparingly and lawfully. Pick from abundance, never dig up roots, leave the bulk of any clump standing, and avoid roadsides, sprayed verges and reserves where collecting is banned. Many wildflowers are protected and the rules differ by country and region, so check before you pick something unfamiliar, and ask permission on private land.

Keeping the Year: A Practical Close

Store pressed material flat, between acid-free sheets, in a box that keeps out light and damp. A shoebox works for a season; a proper portfolio works for years. Group your harvest by season rather than by species — it makes the material easier to find when you are composing, and it keeps the year visible.

Then let the calendar guide you. When the violets appear, press violets. When the leaves turn, press leaves. A collection built this way has a coherence that no single afternoon of gathering can produce, and by the end of a year you will have a press full of small, dated records of where you walked.
