Craspedia Drumstick

Craspedia globosa (formerly Pycnosorus globosus) Billy Buttons / Drumstick Flower / Sun Ball

Geometrically perfect spheres of compacted golden florets, approximately 2–3cm across, sitting atop completely straight, completely unbranched, completely rigid wiry stems — as though someone had stuck golden marbles on the ends of pieces of wire. Craspedia is the sculptural, architectural flower that nothing else in the garden can replicate.

Every other flower in a summer arrangement has something soft about it — petals that curve, umbels that spread, stems that move, edges that are irregular. Craspedia has none of this. The flower is a precise geometric sphere; the stem is perfectly straight; the whole plant reads as the work of a sculptor. In a mixed bouquet or a dried arrangement, a few Craspedia stems create the effect a sculptor achieves by placing a perfect sphere alongside irregular forms — the same visual interest, the same sense of intentionality.

Beyond the sculptural quality, 'Billy Buttons' is also one of the finest everlasting flowers available from seed. The spherical heads dry almost exactly as they appear fresh, retaining their sunshine-yellow colour for years (fading gradually to a warmer mustard tone over time, which has its own appeal). A single sowing produces stems that contribute to fresh summer arrangements and dried winter wreaths alike. Native to the alpine grasslands and meadows of Australia and New Zealand. In the UK, grown as a half-hardy annual — the plants do not survive UK winters outdoors. Up close, each sphere is in fact a dense cluster of hundreds of tiny individual florets packed together into a perfect round, held by a network of fine bracts.

A note on growing

Sow indoors from February to April at 18–22°C. Surface-sow as the very fine seeds need light to germinate; press into moist seed compost without covering. Germination takes 14–21 days. Pot on as seedlings develop and grow on in bright cool conditions. Harden off carefully before planting out only after all risk of frost has passed (late May/June) in full sun and well-drained, lean soil. Craspedia is drought-tolerant once established and genuinely prefers poor, sandy or gravelly conditions — rich soil can produce excessive foliage at the expense of flowers. Space 30cm apart. The straight stems are self-supporting and don't require staking.

Harvesting for fresh and dried use: cut when the spheres are fully formed and have reached their full sunshine-yellow colour — usually mid to late summer. For fresh arrangements, plunge stems immediately into water. For drying, hang upside down in small bunches in a warm, dry, dark place; the spheres maintain their shape and colour for years.

Where it shines

In the cutting garden as a properly sculptural flower for modern, architectural and minimalist arrangements — Craspedia adds a quality to bouquets that no other annual provides. As one of the most reliable dried flowers any cutting gardener can grow. In modern vase displays, where a few stems in a clean glass vessel create an effect that reads as designed. In gravel gardens and Mediterranean-style plantings, where the drought-tolerance and sculptural form suit dry conditions. We grow Craspedia specifically for our dried flower range here at Salle Moor Hall Farm — it's one of the most useful varieties in the everlasting cutting garden.

Plant alongside

For coordinated dried-flower harvesting, plant alongside Bunny Tails, Briza Maxima, Bupleurum 'Griffithii' and Statice for a complete drying garden. For fresh cottage cutting, the architectural sphere shape works beautifully against the soft fluffy whites of Achillea 'Marshmallow' and the airy lace of Ammi majus. For modern minimalist arrangements, combine with the lime-green spires of Bells of Ireland.
