Eucharis × grandiflora Planch. & Linden

Eucharis × grandiflora is a species of flowering plant in the family Amaryllidaceae, native to western Colombia and western Ecuador and widely cultivated as an ornamental in other regions. It is a natural hybrid between E. moorei and E. sanderi. In horticulture it is often confused with E. amazonica, usually differing in its slightly smaller flowers. The English name Amazon lily is used for both species, but is also used for the genus Eucharis as a whole (and for other genera). Despite the common name, it is not closely related to the true lilies.

The broad-stalked dark green leaves are 20–55 cm (8–22 in) long and 10–20 cm (4–8 in) broad. The large showy white flowers are borne in an umbel of three to ten on an erect scape 40–80 cm (16–31 in) long. The flowers resemble narcissus flowers in having a prominent central cup or corona, which is sometimes tinged with green.
