Eucharis–commonly called Amazon lily–is a summer-flowering perennial bulb. It bears umbels of fragrant, daffodil-like white flowers. Each flower has 6 spreading tepals around in two rows, the outer ones longer and narrower than the inner one, and 6 stamens fused to form a cup.
Eucharis has long-stalked ovate or elliptic to lance-shaped glossy green basal leaves that are often wavy or folded.
Eucharis can be grown outdoors in tropical regions; place it in a bed or border in a dappled shade. It can be grown indoors in bright filtered light. Eucharis can be forced into bloom at any time of the year indoors (see below).
Eucharis is a genus of 17 species of evergreen bulbous perennials native to moist forest margins in tropical Central and South America.
