It is best to sow the seeds of Anthericum species such as Spider plant and St. Bernard's lily just below the soil surface at a depth of about half a centimeter, with a spacing of approximately fifteen to twenty centimeters.
Plants are best sown out in the early spring when a frost is still possible. St. Bernard’s lily prefers to be grown in partly shaded conditions. The soil type is not important, but it should have lots of organic matter added to it and kept moist.

When starting Anthericum off from seed indoors, the seeds will take around one to three months to germinate. The seeds should be imbibed by soaking water for half a day then kept at a temperature of around 10 degrees Celsius.
Seedlings can be planted out in either the spring or autumn.
Anthericum are fairly easy to care for, and generally takes thee years to flower after being started from seed; ideally they should be fed in the spring, and watered throughout the summer. In extremely hot summers the plants should be cut back following flowering.
