Syn. Cooperia. Genus around 70 types of bulbous perennials, seen in grassland from North to South America. Zephyranthes Grandiflora (Zephyr Lily) produces 6 in. rose-stalks during the early summer, each displaying a Crocus-like grow which soon opens up out into a pinkish star 3 in. over. Z. yeast infection (white-colored) is even smaller, but there are numerous big-flowering hybrids. The stalks develop fast, into two-3 days.
