About Euphorbia virosa
Euphorbia virosa, also known as mliečnik jedovatý, is a shrubby succulent native to Southern Africa, characterized by its spiny, branching stems that form a candelabra-like structure. Its grey-green stems often develop a reddish tint under intense sun. This plant is ideal for rock gardens, xeriscaping, or as a focal point in large pots in arid and semi-arid climates.
Native range
Southwestern Africa, primarily Namibia and South Africa
Care tips
This Euphorbia requires full sun for optimal growth and intense coloration. Watering should be sporadic, allowing the substrate to dry out completely between waterings, and almost none in winter to prevent root rot. Use a very well-draining substrate, specific for cacti and succulents. A common mistake is overwatering, which is the main cause of death for this species; its latex is toxic and irritating, so handle with gloves.
