The Euphorbia Milii is an easy houseplant to grow. They do not like full summer sun but still require a bright position. Their preferred temperature is around 21 Degrees Celsius (70 Fahrenheit) but they can withstand temperatures as low as 10 Degrees Celsius (50 Fahrenheit). When kept in high temperatures they need to be watered often and will retain leaves and flowers for most of the year, unlike when the temperatures are low, when the Euphorbia Milii needs to be kept dry and will shed its leaves and flowers. One can propagate the Euphorbia Milii from a cutting, but it is not very easy to root.
