The name Eucrosia comes from the Greek for beautiful fringe, a precise description of the long, arching stamens that project well beyond the petals of each tubular flower. These are bulbs from wet montane forests in Ecuador and Peru, where they grow in conditions that are warm and reliably moist during the growing season, then relatively dry at rest. In cultivation outside the tropics, that cycle needs to be replicated: water freely when the leaves are growing or flowers are forming, then keep the bulb warm and dry once the foliage withers. The flowers arrive in spring to summer in loose, nodding clusters on upright stems, and they are genuinely showy.

Eucrosia bulbs are not cold-hardy and are best treated as houseplants or grown in a heated greenhouse in most of North America. They spread slowly by offsets, which should be checked periodically for rot. A well-draining potting mix in a container with generous drainage holes suits them well; they resent standing water at the roots. For gardeners willing to manage their seasonal requirements, the flowering is reward enough.
