Crocosmia Buttercup A compact form of crocosmia, suitable for smaller gardens, Crocosmia x crocosmiifolia Buttercup is a herbaceous, cormous perennial with a clump-forming habit. The sword-shaped, mid-green leaves form a dense clump. In the second half of summer, gorgeous, bright yellow, trumpet-shaped flowers rise above the clump on arching, branched, stems. Crocosmia Buttercup is easy to grow, and can be left in place without attention for several years.
