The crown of thorns plant or Euphorbia milli is part of the spiked plants because its main stem is very similar to that of a cactus, being full of thorns. However, it is a plant from which beautiful flowers grow.

This plant, from Madagascar, lives both inside and outside the home, although it must be taken into account that it can reach up to one and a half meters in height. It is a plant resistant to high temperatures, but not to low temperatures, being convenient that it is indoors in the winter.
