Hello all, I'm hoping to ID this succulent and get some growing tips. Mainly black in colour, with a little dark green/dark red, leaves up to 1 inch/3 cm long. Flowers (from memory) are small, yellow (not bells), sparse and grow on a spike. The plant seems to be on a never ending cycle of doing OK, to looking terrible and over again (no doubt, my fault). I think it would like to hang, if it grew well. My Mum, who has an incredibly green thumb, has trouble growing it also. Thank you in advance.
