I like Black thorn, but you just don't see them here in the states.
Blackthorn is sub-Saharan? We're talking about prunus spinosa, sloe, yes? The kind the Irish make their shillelaghs out of? I'd always assumed the opposite. That it was a cold-climate plant.
Well I assume it's a sub-Saharan tree as south Africa is sub-sahara I could be wrong as I'm no expert but we lay below the Saharan desert which would make it sub Saharan and these trees are indigenous
