I have been growing Euphorbia Milii (also known as Crown of Thorns) for many years and I grow it for many purposes. It makes a nice hedge plant, it is an excellent flowering bush for container gardening, and it adds beautiful colors to a landscape.
Euphorbia Milii is a bushy succulent and bears small yet attractive flowers almost throughout the year. The stem is covered with sharp and dense spines, and bright green leaves near the growing ends. Flowers are red, pink and white though you can find a wide range hybrid Euphorbia Milii that bear more colorful flowers (yellow, orange, cream and many mixed colors). Hybrid varieties are usually grown as grafted plants and display larger flowers.
How to Grow Euphorbia Milii
The actual home of Euphorbia Milii is Madagascar, however it has been successfully acclimatized and grown commercially in many parts of the world. Euphorbia Milii requires well drained soil, moderate water and good sunlight, however, it can survive drought and high temperature. It can be propagated from cuttings that can be rooted or grafted on a stock. When growing from cuttings, allow cuttings to dry for a few days and then plant them in a mixture of moist soil and peat moss. Keep the medium barely moist till plants are established. Over watering would rot these tender cuttings.
Euphorbia Milii can be used as hedge plant, pruned down for edging, grown to cover spaces in rock garden or landscape, or kept as indoor ornamental plant (provided with ample sunlight).
Euphorbia Milii is named after Baron Milius who introduced these plants on France.
