Plant details

Nectaroscordum siculum subsp. bulgaricum is a fascinating species. Growing on tall stems, at first its large, bell-shaped, green and purple flowers hang down from drooping stalks. But, after pollination, the flowers stand erect.

Nectaroscordum siculum subsp. bulgaricum is perfect for using in flower arrangements, and the seedheads may be used in dried flower displays. Frost hardy, these plants require a sunny to partially shaded site and can be grown in rough grass or borders in any moderately fertile soil that is neither too dry nor waterlogged. They can be propagated by freely produced offsets in late summer, or by seed saved in autumn.
