The third is Fatoua, Mulberry weed, a true pest as it's spread around in nurseries. Here is a link that might be useful: Fatoua

First is Euphorbia bupleurifolia, I think, last is crassula muscosa, synonymous with C. lycopodioides. In between that may be an albuca or ornithogallum of some type. Maybe A. 'Augrabies hill' or juncifolia. Black one is Aeonium arboretum either atropurpureum or 'Zwartkop.' -Ming This post was edited by mingtea on Sun, Jul 13, 14 at 0:19

Looks like an aralia-Polysias somethin'-or-other.....
