FAQs

What is the botanical name for Pregnant Onion?

Albuca bracteata, historically sold as Ornithogalum longibracteatum/caudatum.

Can I grow it from seed or only from bulblets?

Both methods work. Seeds are straightforward to start; seedlings take patience to reach flowering size. Bulblets from mature bulbs establish faster.

How long until it flowers from seed?

With good light and care, expect several years (often around 4–6) to reach blooming size.

Is Pregnant Onion edible?

No. This plant is ornamental only. Parts are considered toxic if ingested; sap may irritate skin. Keep away from pets and children.
