It is best to sow the seeds of Sandersonia plant species such as Christmas bells and Chinese Lantern Lily at a depth of about 3 mm (1/8th inch). Do so following the last frost of winter.
Christmas bells and other Sandersonia species like to grow in sunny areas that have good drainage. Ideally the soil should be a loam that is sandy and well manured.
If starting indoors then do so about 10 weeks in advance.
Germination of Christmas bells takes from one to three months at 24 degrees Centigrade (75°F). It is necessary to imbibe the Sandersonia seeds by soaking in warm water for a day before sowing.
Once ready, transplant the young plant into the garden after the last frost with a spacing of 25 to 30 cm (10 to 12 inches).
It should take about three years until Sandersonia grown from seed will first flower.
It is fairly easy to look after Christmas Bells, Chinese Lantern lilies, and other Sandersonia plant species. Provide them with a stake in windy areas, and bring indoors for the winter if you live in a cold climate.
If you require more plants then Sandersonia can be propagated by division in the spring.
