Habranthus is a former genus, now a subgenus of Zephyranthes, of small tender bulbs that flower after rain. The commonly grown members are pink-flowered Zephyranthes robusta and yellow-flowered Zephyranthes tubispatha, and they are easy in warm climates with a dry rest period.

About
Zephyranthes subg. Habranthus is a subgenus within the genus Zephyranthes in the family Amaryllidaceae. It was a formerly recognized as the separate genus Habranthus. It contains tender herbaceous flowering bulbs in the subfamily Amaryllidoideae of the family Amaryllidaceae. It is now included within a more broadly circumscribed genus Zephyranthes. The genus was first identified by pioneering bulb enthusiast William Herbert in 1824.
How to grow it
In the United States, species formerly placed in Habranthus, like other rain lilies, are regarded as "heirloom plants", although not widely used in mainstream landscapes, perhaps because their bloom time, dependent on rain, is erratic. Nevertheless, the bulbs are rugged and easy to grow in USDA Hardiness Zones 8-10 and are recognized among bulb specialists as possessing distinct landscape value in appropriate areas of the world. In colder regions they may be grown in sheltered sites, or in pots kept frost-free in winter.
The most commonly grown species are the pink-flowered Zephyranthes robusta (formerly Habranthus robustus) and the yellow-flowered Zephyranthes tubispatha (formerly Habranthus tubispathus).
