Thorn of Christ: characteristics


Thorn of Christ is the name of a semi-succulent plant that many mistake for a cactus. It belongs to the Euphorbia genus which includes very different plants. Some have a shrubby habit, others are succulent, others still have thorns similar to columnar cacti or globose cactus. This genre is so vast that it can be easily defined as widespread practically everywhere or almost everywhere: in Africa, Asia and America.

Let's get to know specifically the Thorn of Christ, technically known by the scientific name of "Euphorbia milii" to discover its characteristics and even if it is easy or not to grow them in our garden or on our balcony.

Thorn of Christ: characteristics

Originally fromSouthern Africa, this plant has the spontaneous nature of a fairly large shrub, composed of succulent stems and a woody or semi-woody consistency at the base.

Let's take a closer look at these components one by one. Starting from the stems, in the Thorn of Christ they are rich in branches but erect and studded with numerous large spines. When this plant grows and develops in nature, such sharp thorns are very useful for attaching itself to the stem of other trees, which is necessary especially when it reaches a certain height and erect stem it is no longer strong enough to stand alone. The maximum resistance limit is just under one meter.

In the apical part of the branches and near the shoots there are covered with leaves, fleshy, oval and dark green in color but covered with a kind of very sparse hair that makes them more opaque and almost velvety. The state of the leaves makes us understand the health of the plant. If we are watering it too little, they tend to fall while if we are watering ours correctly Thorn of Christ, then we will see one leaf sprout after another.

Starting from late spring, small flowers appear at the apex of the branches and show off a beautiful yellow color with red bracts.

In the garden or on the balcony, the flowers follow the seasons but can appear at any time if the plant is grown indoors.

Thorn of Christ: name

Before discovering how to grow this plant, let's reveal why this name is certainly not obvious and particularly suitable for a plant. There is a legend that explains everything. In fact, it is said that this Euphorbia was used to make the crown of thorns to be placed on the head of Jesus Christ. It is not very credible as a story, mostly because the first Euphorbia Milii to arrive in Europe came from Madagascar, and it was already 1800, before we cannot be sure that it was present in other areas. Nobody can deny a priori but it would certainly be strange given that today there are no specimens of this species in the Middle East.

It should be noted that when it comes to Thorn of Christ we don't want to mean the whole genus of Euphorbia but only Euphorbia milli which is a single species. In fact, in the same category we find succulent plants totally different from each other, over two thousand. They have the flower and a whitish and stinging latex in common within all plants of the genus. Some are succulent like our Milii but not all.
