Euphorbia milii - 'Crown of Thorns'

Euphorbia milii - 'Crown of Thorns'

Although Euphorbia millii is better known as the ‘Crown of Thorns’ those that we see in cultivation are mainly hybrids. These are a succulent plant however they do require a little more water than most.

With bare stems that are covered with rows of sharp thorns, the contrasting crown or foliage and attractive flowers give this plant a bit of a dual personality.

This is a long flowering plant, the nain flowering time is in the winter months, although spot flowers will appear throughout the year. When grown indoors, it can flower almost continually, although it is best to try to give the plant arest during the summer months.

Used widely as indoor plants, they will also grow well in the garden in the warmer zones. The hybrids vary greatly in size, from large growing plants similar to the species, to smaller more compact forms.
