Zephyranthes tubispatha, synonym Habranthus tubispathus, the Rio Grande copperlily or Barbados snowdrop, is a species of flowering plant in the family Amaryllidaceae. It is a perennial bulb native to southern South America (Brazil, Argentina, Paraguay and Uruguay). 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.{{Citation |last=Mathew |first=Brian |year=1987 |title=The Smaller Bulbs |publication-place=London |publisher=B.T.

Description
Flowers are produced sporadically during late summer and autumn, singly on stems {{convert|10|to|20|cm|in|0}} tall. Flowers are usually yellow with copper tones on the outside, with tepals about {{convert|3|cm|in|1}} long, fused for a short distance at the base to form a tube. As with all former Habranthus species, the flowers are not upright on the stem but held at a slight angle. The leaves are not normally present at flowering time, appearing later; they are narrowly linear.
Chemical composition
Cultivation
Zephyranthes tubispatha tolerates some frost down to {{convert| 0|C|F|abbr=on}} if planted in a sheltered sunny position, but will not survive being frozen. It seeds freely. A form with pinkish flowers is grown as var. rosea, but may be a hybrid.
Z. tubispatha has gained the Royal Horticultural Society's Award of Garden Merit.{{cite web|title=RHS Plant Selector - Habranthus tubispathus|url= https://www.rhs.org.uk/Plants/8195/Habranthus-tubispathus/Details | accessdate = 5 July 2020}}{{cite web | url= https://www.rhs.org.uk/plants/pdfs/agm-lists/agm-ornamentals.pdf | title = AGM Plants - Ornamental | date = July 2017 | page = 44 | publisher = Royal Horticultural Society | accessdate = 3 March 2018}}
