About Urceolina amazonica (Linden ex Planch.) Christenh. & Byng
Urceolina amazonica is an evergreen bulbous perennial. It grows up to 75 cm (30 in) tall and 50 cm (20 in) wide, with long, narrow, dark leaves, and umbels of fragrant white flowers that have six tepals. The stamens are fused at their bases, forming a staminal cup in the center of the perianth. The free sections of the filaments are subulate and flat. This species is a sterile aneutriploid with a chromosome count of 2n=3x−1=68. For cultivation, since it is not cold-hardy, it needs a sheltered growing location and protective winter mulch in colder climates. It has been awarded the Royal Horticultural Society's Award of Garden Merit.
