Growing Notes

Surprisingly cold-hardy for a succulent spurge (a testament to this is the well established specimen growing in the ground at the UC Berkeley Botanic Garden).
As with all euphorbias, wash sap from skin and eyes immediately.

Special Interest

Flowers in the aggregate can be quite showy.
