Plant of the Week

Crinum bulbispermum – Pink Hook Lily

An extraordinary plant native to southern Africa. Starting as early as June, large, fragrant flowers in delicate shades of pink and white appear, floating elegantly above the long, arching foliage. Despite its exotic appearance, this impressive plant blends surprisingly harmoniously into perennial plantings. Over the years, Crinum bulbispermum develops into a stately and long-lived plant. In a sunny, sheltered location, it thrives reliably and becomes more beautiful with each passing year. Its long, strap-shaped leaves form an attractive clump that adds texture to the planting even outside of the flowering season. The exceptionally large seeds that form after flowering are a real eye-catcher. They add to the plant’s ornamental value well into the fall and highlight its unique character.

Plant of the Week

KW 22

Tulipa sprengeri – Sprenger’s tulip

A tulip marvel! The bright, pure-red flowers of this very late-flowering tulip species are, despite their striking colour, incredibly elegant. Depending on the year, this rare geophyte beauty does not flower until late May or early June. The combination with the purple flowers and burgundy foliage of other early summer plants is magical! Here, Tulipa sprengeri grows best in a densely planted semi-shaded border amongst Thalictrum, Polygonatum and Geranium nodosum ‘Fielding’s Folly’. Despite the fairly dense planting, it self-sows reliably here
