Euphorbia supernans Dr.
G. C. Nel
Location: South Africa Cape Province.
One of the CAPUT MEDUSAE GROUP of which there are several very close
species, which makes for difficulty in distinguishing one from another.
This plant could be very easily be:-
Euphorbia flanaganii or
Euphorbia inermis or
Euphorbia woodii.
If this plant is the one I think it might be, there is a further complication,
in that the name is sometimes referred to as E. superans.
I have now purchased several volumes of "The Euphorbia Journal"
which has an identification guide using the floral characteristics.
So the next time the plant flowers, I should be able to make a definitive
decision on its name. Till then I will use the name that came with the
plant when I purchased it.

Cultivation:
Requires warm conditions all the year round ideally 9ºC, will tolerate
4/5ºC if kept on the dry side in the winter. Full light is essential
at all times combined with a well drained poor-ish compost should prevent
etiolation of the branches.
In the active growing season the plant will take all the water one can
give it.
Yellow flower inflorescences in late spring early summer.
Propagation:
As this plant produces lots of seed that is the best way to produce
new plants.
From cuttings of the branches in Summer but not recommended due to the
resulting caudex tending to be lob sided. Always spray bleeding surfaces
with water after cutting to coagulate the sap.
WARNING: All Euphorbia sap is more or less poisonous take appropriate
care.
