One of my most lustful plants has been the super cute Euphorbia clavarioides var. truncata. I first ran into this fascinating poinsettia cousin at the Denver Botanic Gardens in the 1990s, and have subsequently killed it 5 times, prior to the construction of our crevice garden. Now, our specimen below is 2.5 years old and thriving. The key is perfect drainage and no water in the winter.
Below is a giant clump, which we saw in the wilds of South Africa in 2005. These massive clumps are considered to be well over a century in age, so our little patch has a lot of growing to do.
Pretty euphorbia. Please tell me what “HCG form” means.
That’s simply our source designation, since not all clones have the same winter hardiness, we track the genetics of each. Our original plant came from the late David Salman of High Country Gardens (HCG)
