Euphorbia erythraeae - Desert Cactus

If you're after a structural, statement cactus, this one may be The One. Euphorbia are not technically true cacti, but these ones are adapted to the same conditions, and grow in similar shapes, so the end result is the same. It's just technically called a succulent tree, and from a different part of the world to cacti. Phew, now that's cleared up - this spiky boi has four ridges lined with wicked spikes, and will branch quite a lot in that cactus-y candelabra shape. It's a great silhouette and the big spikes mean they are easy to avoid too. The mid-green flesh of this plant's succulent trunk is textured with the raised lines which mark this species out, and the edges where it's spiky crinkle slightly, adding to the character of the plant. If you have a window spot with plenty of sun needing a plant, this could be the one for you!

Scientific Name
Euphorbia erythraeae

E. erythraeae is a synonym of E. abyssinica.

Common Name
Candelabra Tree, Candelabra Spurge

Origin
Native to Ethiopia, Somalia, Sudan and Eritrea.

Light
Your Euphorbia will thank you for giving it lots of light, and loves as much direct sun as it can get its branches on. This is the perfect plant for a bright south- or west-facing window.

Water
This cactus cannot cope well with having constantly-moist soil, so make sure it dries out totally between waters. If your plant is in a position with less direct light, be extra careful not to overwater it!

Humidity
This cactus is adapted to arid (dry) conditions so does not need a humid location at all. If it's getting dusty feel free to hose down to clean, just make sure it can dry out quickly.

Soil
Use a well-draining soil designed for cacti and succulents, usually a mix with added grit and sand. Repot every three to four years in spring as the plant grows.

Food
Feed every other water in spring and summer; reduce to every three in autumn and winter.

Temperature
Average temperatures of 15-32°C are fine; make sure it doesn't get colder than 12°C in winter.

Pet-safe
No, this plant is toxic to pets and small humans, as well as having sharp spikes!

Sprouts Top Tips
If you notice brown discolouration on your Euphorbia's stems, check closer before you act; if it is soggy you may need to take cuttings to save it, but if it is 'corking' and the brown is more like hard scabs, this is natural and not a concern. In mature specimens, this becomes like a tree trunk!
