Euphorbia is a very large genus of plants with more than 2,000 species. About 1,200 of them are succulents, some with bizarre shapes and wide, fleshy leaves and others that look remarkably like cacti, complete with spines. Growers commonly refer to plants in the genus as euphorbia or spurge.
Simply so, how many varieties of Euphorbia are there?
Additionally, how do you identify Euphorbia?
How often should you water euphorbia?
Water: Water your euphorbia every two weeks in the summer time, but triple check that the soil is completely dry between each watering. When watering make sure the water is drainage through its growers nursery pot. The biggest killer of this beauty, is over watering resulting in root rot.
New leaves will grow at the top of the stem in a couple months. In nature, I can grow to be as tall as 30 feet. Indoors in a container, I will grow fast and can get to be 5-8 feet.
Some euphorbias thrive in dappled shade in the garden. Known for their striking foliage and brightly coloured leaf bract, which surround the tiny flowers, they are generally easy to grow as long as the soil isn’t very dry in summer.
Categorised as a flowering plant in the spurge family, euphorbia is labelled as “poisonous” and a “skin and eye irritant” by the Royal Horticultural Society (RHS). In the Indian Journal of Ophthalmology, it says: “The milky sap or latex of Euphorbia plant is highly toxic and an irritant to the skin and eye.”
Among laypeople, Euphorbia species are among the plant taxa most commonly confused with cacti, especially the stem succulents. Euphorbias secrete a sticky, milky-white fluid with latex, but cacti do not.
Euphorbia are plants that want warmth; south- or west-facing windows are the best place for them inside (four or more hours of direct sun shining on the plant), though they can also be grown in very bright indirect light.
Height to 2.5ft (75cm). Euphorbia epithymoides (polychroma) is an evergreen perennial with mid-green leaves and sulphur-yellow flowers and bracts, in April and May.
Just because euphorbias can survive drought, does not mean that they need it. In fact in the growing season regular and copious watering is required. Most species do not appreciate dust dry soil in the resting season, and need a little water from below, or even carefully from above.
