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 25°F but the bulb, even exposed, seems hardy to 20°F or a little less and quickly rebounds in warmer months - our oldest garden plant survived the 18°F 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.
The information about Crinum asiaticum that is displayed on this web page is based on research conducted in our nursery's horticultural library and from reliable online resources. We will also include observations made about this plant as it grows in our nursery gardens and other gardens that we have visited, as well how the crops have performed in containers in our nursery field. We also incorporate comments that we receive from others and welcome hearing from anyone with additional information, particularly if they share cultural information that aids others growing this plant.
Please note that after 46 years in business, San Marcos Growers will be discontinuing nursery operations by the end of 2025 and the property will be developed for affordable housing.
