History: King Juba 11 (50 BC to 19 AD) of Numidia (present day Algeria)
was the first person to collect succulent type Euphorbia and named the plant
after his Greek physician Euphorbus. Milii Was named for Baron Milius,
once governor of the island of Bourbon, who was responsible for introducing
the plant into cultivation in France about 1821.

The common name refers to legend that a crown of thorns was placed on
Christ’s head at the crucifixion. It could have been used as it was
introduced to that area from Madagascar some years before the time of Christ.

Temperature range well above frost
Light Bright light to full sun
Water often in summer -- 2 or 3 time a week in the sun; in winter when the plant is inside water less often.

The Euphorbia milii is a woody succulent with thorns. The plant ranges in height from a few inches to 6 7 foot tall single stalks or small shrub the size of a soccer ball. Some make a perfect plant for hanging basket because they cascade down.

Flowers range in color from deep red to white to multicolor and in size from
tiny, less than size of a BB, to one-half inch. On some of the older types you may find red spots on the leaves. Leaves are found mostly on the tips of the plant where flowers appear either single or in pairs. In China where it is called “PoySean” “Poy” means 8 and “Sean” means saint. If the plant has 8 flowers in a bundle, you will be lucky. For many years I have had these plants in my collection and find it is quiet easy to propagate from seeds, grafting or cuttings. I prefer rooted cuttings. It is quick and easy. Take the cuttings from the top portion of the plant, remove most of the leaves add Rootone or Hormondin and let dry for a couple days in low light. Then place in a 50 percent mixture of potting mix and sand. Keep the potting mix damp BUT NOT WET in the shade. In a couple weeks you will have flowers.

As for insects, you may have some scale, mealy bugs, and sometime aphids. But usually this only occurs on weak or sick plants. I use two tablespoons of liquid soap in a quart of water.

Plant in well drained soil. If roots stay too wet the plants will drop all leaves and die.

Caution:: This plant is in the Euphorbia family and is a mild poison. It bleeds
a white sap that when coming in contact with some people’s skin reacts like Poison Ivy. When the sap comes in contact with eyes, wash with running water and see a doctor. Never plant near a fish pond since the exudate from broken roots will kill fish.
