Plant Subject: Crown of Thorns (Euphorbia milii)

First impression: Lipstick red, tiny bright blossoms cover a very well armed plant. Thorns, a.k.a. barbs, blanket every stem of this low growing shrub. Leaves are green and sparse. Somewhere under all these teethed stems we may find a beginning, but I’m not looking! No fragrance that I can detect, but pollinators are all around. A sticky situation might occur if you try to pick these blossoms; you can look, but don’t touch this unique bloom.

Upon further investigation: Crown of Thorns really describes this multi prickly plant. Euphorbias include a whopping 2,000 plus species of tropical, drought tolerant plants. Our star got its name long ago as it resembles the spiny crown that was placed on the head of Christ during crucifixion. If you can learn to admire the thorns, Crown of Thorns will be very popular in your garden because it’s always blooming.

Each blossom consists of two petals in a heart shape surrounding a tiny floret. Each bloom, usually four, is connected to a thin stiff stalk, which is attached to the main flower stem. So many prickly stalks make for oodles of ever blooming flowers. These slender stalks create dancing flowers when the wind blows.

Bees love the blooms and can be seen all day feeding on the sweet nectar. Brown and Green Anoles, small mammals, and snakes find shelter under and around protected by the plant’s spiny stems.

In the last decades, Crown of Thorns varieties have evolved. Yellow, white, pinks colors, which are great for options. Larger sized flowers and leaves can be found. Crown of thorns is a slow growing, may reach 2-3 feet in height, and can sprawl to just as wide. Pruning can be done carefully, but really not necessary.

Propagation is usually by division. Always wear thick leather gloves and long sleeved shirt. Wrapping a long rolled-up section of newsprint or fabric around a pad provides a convenient handle that avoids the long spines.

Dig up, or cut, stems can then be cut off larger plants with hand clippers. The cut stems wound should dry for about three days. I place mine in shady area under bushes etc. Plant the wounded stem with the wound in the ground. The wound will establish the new Crown of Thorns with roots. Whaa-la: Another fabulous addition, which will reward you for many years with the yen and yang of flowers and thorns.
