Crinum asiaticum (Giant Crinum) - A large evergreen bulb that can grow to be a 5 foot tall by 6 foot wide specimen with 4 inch wide by 4 foot long semi-succulent light green strap-shaped leaves that are held semi-erect in a spiraled rosette at the top of the collar of the 6 inch wide bulbous base. In warmer climates this plant can send up on 2 foot sturdy stalks its fragrant clusters of 20 to 50 white flowers, with long tubular bases and narrow petals year round, but in Southern California flowering is primarily late spring through summer. Plant in moderately well-drained soil in full to part day sun or light shade. Tolerates only occasional to infrequent irrigation but grows faster with a regular watering. - foliage can be damaged by temperatures around 25F but the bulb, even exposed, seems hardy to 20F or a little less and quickly rebounds in warmer months - our oldest garden plant survived the 18F experienced during the Christmas 1990 frosts. Great for adding a tropical look without requiring much moisture or as an interesting specimen in the ground or in a large container. Seed self set and are easy to grow but plants require years to become large and flower. All parts of this plant are considered poisonous to ingest and some claim the sap can cause dermatitis. This plant is native to tropical southeastern Asia but has long been planted in Southeastern States and California. Our plants from seed off a plant that was found growing in 1983 at the historical Sexton Nursery property in Goleta, CA. 

This information about Crinum asiaticum displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
