Sometimes the common name of a plant can give you a hint of when flowering occurs. For most of the year, Euphorbia leucocephala is a rather ordinary shrub. But as the holiday season approaches, its common name, little Christmas flower, makes perfect sense.
From early November, through December into the New Year, the shrub transforms into an airy white cloud of delicate, sweet fragrance. Like the poinsettia, to which it is related, the “flower” in little Christmas flower are actually bracts.
Once the bracts have all dropped, you can prune the shrub which can grow up to 10 feet until August, but not after that, or you’ll have no blooming the coming season. Wear gloves when pruning; the milky sap can be irritating. Native to Mexico, little Christmas flower is best for zones 10a-11. It grows best in full sun and well-drained soil. Avoid planting it under street lights, as it needs darkness to bloom just like its poinsettia cousins.
