About
Colchicum 'Glory of Threave' is a perennial plant that grows from corms and features slender, upright flowers that emerge in the autumn. Each flower consists of a cup of glossy, pinkish-purple petals, centered with a white star, and attached to a dark purple perianth tube. In spring, it produces narrow, semi-erect leaves that reach around 20 cm in length, which will fade by summer.
