5 Seeds Ornithogalum caudatum Pregnant Onion Bulb Plant

Ornithogalum caudatum, commonly called the Pregnant Onion, is a curious bulbous plant grown for its unusual appearance and easy-going nature. It produces a large, exposed green bulb that develops small offset bulblets on its surface, giving it a distinctive, conversation-starting look. It makes a fascinating specimen for collectors of unusual plants and a rewarding plant for growers of all experience levels.

This plant is primarily grown as an ornamental curiosity for containers and indoor collections, where the swelling bulb and cascading strap-like leaves add texture and interest. It is a low-maintenance grower that performs well in bright light and well-draining soil, and it can be kept as a houseplant or moved outdoors in warm conditions. Offsets that form on the bulb can be removed and grown on to produce new plants.
