Most flowers we grow are what a florist would call focal flowers — the roses, dahlias, cosmos and zinnias that carry colour and draw the eye. They are wonderful, but a border or a bunch made only of focal flowers looks busy and slightly anxious, like a room full of people all talking at once. What's missing is the quiet element that gives the eye somewhere to rest and everything else room to breathe.

That is the job of the umbels. Their flat, horizontal plates of tiny flowers do three things at once that nothing else does so well. They contrast — the flat lace against the round rose, the spike of the snapdragon, giving a planting variety of shape rather than just variety of colour. They connect — drifting the same airy white (or smoky pink) note through the whole scheme so that separate flowers read as one composition. And they bring movement and transparency — you look through them to the flowers beyond, so a border gains depth and a bouquet gains that loose, gathered-from-the-garden softness that is so hard to fake.

Flower farmers and florists know this, which is why umbellifers are grown by the fieldful and why a single packet of lace seed will do more for your cutting patch than almost anything else you could sow. They are the plants that make everything else you grow look better — the definition of high leverage.

Here is the crucial part, and the reason we're flagging these now rather than later. You can sow all three in spring — but you'll get a fraction of the plant. To grow lace the way the flower farmers do, sow it in autumn, in September and October, just a few weeks from now.

These umbellifers are hardy annuals and biennials that positively want a cold start. Sown in autumn, the seed germinates in the still-warm soil, makes a sturdy little rosette of ferny foliage and — most importantly — sends down a deep, strong taproot before winter arrives. It then sits quietly through the cold, and the moment spring stirs it romps away from a position of real strength. The result is a plant that flowers weeks earlier, stands far taller and stronger, on longer stems, and produces many more flowers over a much longer season than anything you could sow in spring.

There's a second reason too. Orlaya in particular can be slow and erratic to germinate, and the natural cold of an autumn sowing genuinely improves and evens out its germination — it's simply the way the plant expects to grow. And because all these umbels resent having their long taproots disturbed, autumn is the ideal time to sow them where they are to flower, or into deep modules or root-trainers for planting out while still small.

If the lace trio has a leader, it is Ammi. The classic bishop's flower gives you great, frothy, flat-topped domes of the tiniest pure-white flowers, held high on tall, elegant stems above finely-cut, fern-like foliage. It is the airiest and most refined of the three — a true veil, so fine you can scatter it right through a planting and see straight through it to everything beyond. It is the florist's single favourite filler for exactly this reason, giving instant cottage softness and a wonderfully long vase life.

The Classic Veil

Ammi majus

Bishop's Flower

Tall, frothy domes of pure-white lace on elegant stems above ferny foliage — the florist's favourite filler and the airiest veil in the cottage garden. Best from an autumn sowing for the tallest, strongest plants.

Orlaya is the connoisseur's lace — and once you've grown it, you'll never be without it. Where Ammi's flowers are uniformly tiny, Orlaya's flat white umbels are ringed with dramatically elongated outer petals, so each flower head looks like a little lace doily or a ring of white butterflies. It's showier and more clearly "flowering" than Ammi, and at a more modest height it earns a place towards the front where its intricate flower heads can be admired up close. Also known as white lace flower or Minoan lace, it is exquisite fresh and dries beautifully too. This is the umbel that makes people ask what it is.

The Refined Jewel

Orlaya grandiflora

White Lace Flower / Minoan Lace

Intricate white umbels ringed with elongated outer petals, like rings of tiny butterflies — showier and more refined than Ammi, and a connoisseur's favourite. An autumn sowing genuinely improves its germination.

And now for the one that breaks the rules. Daucus 'Dara' is the ornamental cousin of wild Queen Anne's Lace, and instead of white it gives you the same beautiful flat umbels in an extraordinary range of smoky colours — dusky pink, rose, deep wine and rich chocolate-maroon, often several shades at once and deepening as the flowers age. It's the trendiest filler in modern floristry for good reason: it brings all the connective, structural magic of the lace form, but with moody, sophisticated colour instead of white. Thread it through a scheme and it adds depth and a smoky, antique richness that no white flower can. Where Ammi and Orlaya lighten, 'Dara' deepens — which is exactly why the three of them together are so much greater than the sum of their parts. (Prefer the pure-white original? We grow the classic wild Daucus carota too.)

The Moody One

Daucus carota 'Dara'

Chocolate Lace Flower

The lace form, but in smoky dusky pink, wine and chocolate-maroon — often several shades at once, deepening with age. Modern floristry's favourite moody filler, bringing depth and antique richness where the white umbels bring light.

The trio share a flower shape and a sowing season, but each brings something distinct — which is precisely why the cutting garden wants more than one. Here's how the lace umbels differ, along with the wider family members worth an autumn sowing too.

The three lace umbels are the heart of it, but the cow-parsley family runs deep, and a few more are well worth an autumn sowing if you've caught the lace bug. Two in particular earn their place in any cutting patch.

The Green Lace

Bupleurum griffithii

Hare's Ear / Thorow-Wax

Zesty lime-green starburst heads above blue-grey leaves — the hardy-annual answer to acid-green euphorbia, and the foliage-flower that makes every other colour sing. Autumn-sow with the rest of the lace family.

£1.95 View Seeds →

The Smoky Foliage

Bronze Fennel

Foeniculum vulgare 'Purpureum'

Tall clouds of smoky purple-bronze filigree foliage topped with flat gold umbels — the umbellifer grown as much for its haze of feathery leaves as its flowers, and a superb foil for brighter colours. Sow in autumn for strong plants.

And for something from the same family but the very opposite of soft, the spiky steel-blue Sea Holly (Eryngium) brings architectural, thistle-like contrast rather than airy lace — a striking foil to all that froth, just as happy sown in autumn, and wonderful both fresh and dried. Grow it alongside the lace and you have the full range of the umbellifer family, from the softest veil to the sharpest steel.
