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.”
Keeping this in view, are Euphorbia and cactus same?
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.
Herein, is a Euphorbia a cactus or succulent?
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.
Can Euphorbia cause a rash?
Many euphorbias have gray-blue foliage with lime green flowers and characteristic milky latex sap, which quickly congeals when exposed to air. The sap contains esters that cause skin rashes and pain.
Euphorbia occupies a very wide range, from tropical areas of Africa (where most of the succulent Euphorbias originate), Madagascar, and the Americas to warmer, temperate areas of Asia and Europe. Euphorbia species can also be found in the Pacific Islands and Australia.
What makes a Euphorbia? All flowers in the Euphorbiaceae are unisexual (either male or female only), and they are often very small in size. In Euphorbia, the flowers are reduced even more and then aggregated into an inflorescence or cluster of flowers known as a “cyathium” (plural cyathia).
Cut off a healthy, unblemished stem end about 5-7 inches long. Use a clean razor blade or sterile sharp knife. Cuttings root best during the hotter times of the year. Take the cutting, and let it callus over for a few days or so.
Euphorbias in general are sun lovers, though some will tolerate partial shade. Those with deep-purple or reddish foliage will have more-intense coloring if planted in full sun. … Euphorbia amygdaloides var. robbiae is a popular choice that grows well in shade.
Even a “euphorbia that blooms readily” needs a lot of light, even full sun, watering when the soil is dry, but not super dry, reasonable temperatures (very few enjoy cold winters), modest fertilization, etc. to be happy and only a “happy euphorbia” will flower.
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.
