one i brought back from the dead, and it flowered like crazy...the other is a small seedling given to me, that was planted in pure coffee grounds...it did really well, and continued to thrive after being potted in regular peat based potting mix.
aphids get all over these, but they get mummified by the parasitic fungus that I spread on them! its fun to do. Hosing them off works well to, but tears leaves when you really spray hard.
I hope to get pods in the next 2yrs...not sure though...this one grows slow through winters, and took months to bring back to green and happy.
