Dwarf Euphorbia 2
The Somalian Euphorbia sepulta is a true dwarf as it produces globular shoots only 2 to 3 cm. Slowly growing with the age the plant builds a dense cushion.
I so far failed to grow Euphorbia sepulta on its own roots but see my grafted plants living long and prosper. Frequently used stocks for E. sepulta are over here E. canariensis and resinifera. The latter seems to induce an earlier and more opulent bloom.
Btw, as you see I figured out how to show thumbnails side by side. :-))
