Euphorbia 'Crown of Thorns'
The crown of thorns plant (Euphorbia milii) is a unique houseplant, as it’s one of the few succulents with real leaves that are thick, fleshy, and tear-shaped. The leaves appear on stems that are armed with sharp, inch-long spines.
This succulent plant needs lots of sunlight. Position it in a bright, sunny window on the west or south side of your home. Growing the plant is easy because it adapts well to normal room temperatures and in dry indoor environments. It also forgives occasional missed waterings and feedings without complaint. Average room temperatures of between 65-75 degrees Fahrenheit are fine.
