If at first you don’t suceed, plant and plant again

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.

We have long loved small crevice-sized succulents, but have also killed far more than our share, due mostly to our wet, cold winters. The newest star in our trials is the South African, Rabiea albipuncta, a first cousin to the better known, Delosperma. We should mention, that new DNA research has actually suggested a name change to Nananthus vittatus would be more correct, so we’ll be re-tagging shortly.

This gift from Denver Botanic Garden plantsman extraordinaire, Panayoti Kelaidis, has thrived in the gardens since 2018. We actually tried this back in 2004, but our site simply didn’t drain well enough in winter. This image was taken here at JLBG on February 2 this year, which shows how insanely tolerant the flowers are of cold weather. We hope to make this available next year through Plant Delights Nursery. This gem forms a substantial caudex, and as such is highly prized by bonsai enthusiasts.
