I'm having an end of summer sort of my plants, so have quite a few to dispose of one way or another, plus a few I'd like, not that I actually have the room:

If you don't have any swaps, I'm happy to sell at a cheap price (£1.50, £1 if buying 5 or more) for most of these.
Plants marked S are not often offered, and/or I don't have many, so I'd want a slightly higher price on these.
Postage for sales is £3.35 for UK.

I'm open to suggestions on any nice plants including miniature Crassulas / Crassulaceae, nice shaped mini-shrubs, cold hardy columnar or unbranching cacti, more unusual plants worth trying outside in Birmingham UK (so no Semperviviums, or common Sedums) and various choice Euphorbias, including, but by no means limited to:

Aloe polyphylla
Aloe ramossissima
Ceraria

Calibanus hookeri
Euphorbia squarrosa / stellata
