So strange- I've just joined hive today. I grew up in Kommetjie! What tiny world.
I'm also into gardening and whatnot- Live up the Garden route now. That unknown plant of yours looks like it could be a White Stinkwood (Celtis africana) or maybe Grewia occidentalis. Pretty sure it's a stinkwood though! May be the chinese variety, Celtis sinensis
