Euphorbia marginata: seeds

Euphorbia marginata, known in English as "snow-on-the-mountain" and in French as euphorbe panachée, is an annual native to much of the continental United States. The small white flowers are surrounded by whorls of showy green leaves edged with white.

This is my first year growing Euphorbia marginata. I was pleased to see that the seeds are fairly large and easy to handle. Ironically, although this is a North American native and I ordered seeds from a North American company (Stokes), these seeds are from the Netherlands!
