376:. It is hardy to USDA zones of 9a-10b. The ornamental value of this plant is based on the formation of bulblets. The common name "pregnant onion" is due to the small adventitious bulblets that form from the initial bulb scales, which are likened to "babies". It is frost tender, and requires light well drained soil, and bright light, although intense heat and light can scorch tissues. Consistent watering is required for seed germination and survival. Mature plants will benefit from slight drying between waterings, although underwatering will induce dormancy. During the winter months this plant can be allowed to go dormant and the bulbs stored at cooler temperatures.

As of 2012, it had stable native populations with a conservation status of "least concern". It grows at altitudes of 0–300 m above sea level.

Strap-shaped lanceolate leaves, 60 cm (2 ft) long and 2.5 cm (1 in) wide, protrude from a bulky bulb which is largely above ground. The roots are white and succulent. Many small, fragrant, white flowers, with a diameter of 0.5 cm and a green midvein, are located on
