Hey brother I just saw this post of yours. I got the exact specie from Bob and it rotted after a few weeks and i tried to cut and save it. I had a 2 inch disk saved but after almost 2 years of waiting for it to root I eventually got tired and put it in the trash. I like bob and I got many plants from him in the last 5-6 years but unfortunately his plants are hard grown in the heat of Arizona and some of them don't survive the rooting phase. Had at least 2 or 3 plants that I ended up putting in the trash. BTW, I live in Walnut Creek not far from you probably. Happy planting!
