About

Albuca bracteata (syn. Ornithogalum longebracteatum), is known by the common names pregnant onion, false sea onion, and sea-onion. It is a species of bulbous flowering plant in the family Asparagaceae. Its flowering stems can reach a height of 90 cm and can carry up to 100 greenish white flowers.

How to grow it

Albuca bracteata is primarily grown as a houseplant. 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.

Where it grows

Albuca bracteata is native to South Africa (the Cape Provinces and KwaZulu-Natal). It is also found in tropical east Africa, where it may be native or introduced. It can be found growing in forests, forest margins, closed woodland and sheltered slopes. 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.
