Crocosmia 'Solfatore'

This is a hybrid of a Montbretia variety that has been around for over 100 years, selected in France in 1887.

Floral Morphology 

The flowers of Crocosmia × crocosmiiflora 'Solfatare' are zygomorphic — that is, symmetrical along a single plane — and composed of six tepals arranged in two whorls of three, the inner and outer petals forming a loosely star-shaped, funnel-like bloom approximately 4 cm in diameter.

The warm apricot-yellow perianth tube opens outward into spreading, slightly reflexed lobes. Stamens and style project forward from the tube, facilitating contact with visiting pollinators.

Flowers are arranged in a distichous, branched spike — a cincinnus — with individual blooms opening in sequence from the base upward over several weeks, maximising the pollination window.

Ecology 

Native to the grasslands, scrub margins and stream banks of South Africa, Crocosmia evolved in environments with warm, moist summers and dry winters — conditions that shaped its corm-based storage strategy, allowing it to survive seasonal drought underground.

Its tubular, brightly coloured flowers are adapted for pollination by long-tongued insects and, in its native range, sunbirds. In European gardens it is visited primarily by bumblebees and hoverflies.

Where conditions suit it — sunny, fertile, well-drained soil with adequate summer moisture — it spreads vigorously via stolons connecting successive corms, forming dense, naturalised colonies.

In some mild, humid regions such as western France and the British Isles, it has naturalised so successfully in the wild as to be considered locally invasive.
