With all the cacti blooming, I haven't paid much attention to the succulents. But I saw this new growth yesterday (I obviously had missed a lot) and really liked the different colors. The difference is more startling than the picture suggests.
Your first question... It happens to my Euphorbia baioensis too but there doesn't seem to be anything wrong. I put it in the full sun though, maybe that's the cause.
Noorsveldensis means "from Noorsveld". Noorsveld is a place in the Cape Province.
Noord means north in Afrikaans. Dieter, does Noors mean anything in Vlaams?
Mike, it may be a place name, although I wonder if it's a misspelling. Perhaps "Noordsvelt" or something? The North Plains? Velt in Afrikaans is like a plain, prarie, savanah etc...
Well, South-African is a language that sprouted from the Dutch spoken by discoverers. Noorsveld indeed probably means from a field in the north. "Veld" is field in Dutch, Noors comes from "noord", meaning north.
