Here’s a couple of unusual Euphorbias for your perusal and enjoyment. Please don’t eat them though since they’re poisonous enough if you eat them or get the latex sap on you.
Euphorbia loricata has old bloom panduncles still on the stem from last year. I just made up that word. Maybe Rikki knows what the correct word is. Or you can look here and figure it out for yourself. For instance, they list a Euphorbia’s cyathia in an umbel.
And then the more popular Euphorbia anoplia since it is a very scenic plant. Scenic in the architectural concept of things and such stacked up around each other.
