About

Urospermum dalechampii is a perennial herbaceous member of the Asteraceae that bears sulphur-yellow flower heads. It forms a low rosette of toothed leaves with one or more upright stems and typically reaches about 0.5 m. Flowering runs from May to August in the UK when the bright heads are most obvious. The mature heads develop beaked achenes with a feathery pappus.

In the garden

Urospermum dalechampii originates from Mediterranean regions including Spain, Sicily, Sardegna and North Africa, where it favours open, sunny sites. In UK gardens it flowers from May to August and provides low, upright stems topped by sulphur-yellow composite heads. Grow it in full sun on sandy, loamy or clay soils that are moist but well drained; good drainage is important on heavier substrates. Plant to a depth matching the root ball and allow some air around the crown to reduce rot in wet winters. The species carries a fully hardy rating (H7), so it tolerates UK winter temperatures in most situations; it also corresponds to USDA zones 5–9. At roughly 0.5 m high it suits mixed gravel beds, Mediterranean-style borders or sunny edges of herbaceous borders where a low, flowering perennial is wanted. The flower heads are followed by beaked achenes topped with a feathery pappus, a diagnostic feature that helps with identification once blooms have finished. Situate plants where their seed heads can be seen up close if you want to examine the achenes and pappus.
