Zephyranthes tubispatha, synonym Habranthus tubispathus,[1] the Rio Grande copperlily or Barbados snowdrop,[2] is a species of flowering plant in the family Amaryllidaceae.

It is widely cultivated as an ornamental and reportedly naturalized in the southeastern United States (Texas, Louisiana, Alabama, Georgia, Florida), much of the West Indies as well as Bermuda, eastern Mexico, India, Easter Island, and central Chile.

[3] Flowers are produced sporadically during late summer and autumn, singly on stems 10 to 20 centimetres (4 to 8 in) tall.

Flowers are usually yellow with copper tones on the outside, with tepals about 3 centimetres (1.2 in) long, fused for a short distance at the base to form a tube.

[4] Zephyranthes tubispatha tolerates some frost down to 0 °C (32 °F) if planted in a sheltered sunny position, but will not survive being frozen.
