Propagation
This plant can be rooted from stem cuttings. As is with almost all of the Euphorbia when you take the cutting the plant will bleed a sticky, white sap (not a good substance to get into the eyes, cuts or sensitive skin). The cuttings have rooted best during the hotter parts of the year....Take the cutting... let it callus for a day or so....I use perlite to root it in....bury the cutting in the perlite 2-3 or more inches depending on the size of the cuttings...use a layer of coarse rock to add support to the plant and weight to the pot so the cutting won't tip....with perlite the chance of over watering is almost eliminated...put in a moderate light area and keep warm...this has worked for me...be patient.
Native Site
Tropical West Africa, Gabon, Southwest Africa
