Program

Euphorbias II – Spiny Shrubs and Mound Formers. Robert Webb has been giving a series of talks about Euphorbias. In this installment, he explores some of the intermediate-scale species of Euphorbia. The focus will be on plants in Yemen, East Africa, South Africa, and Namibia with some limited discussion on horticulture and propagation. Using an approach of mostly field-cultivation images, he will discuss some of the interesting species of Euphorbias in these two groups.
