Name: Kate Holmes Beach, FL (Zone 10a) Not all those who wander are lost.
Here's a pic of the Caralluma piaranthoides (a piece that fell off when I was taking it home ). At least that's what I think it is...that's how it was labeled at Tropiflora (the nursery where I found it). Though I read that many Carallumas are being reclassified as Pachycymbium.
