When purchased Su1 had one small flower, five yellow petals with a mid rib black stripe.
Some results of finding a truly useful plant whose mucilage can be used in field grafting.
Best so far in order of my preference:
Succulent, above photo, I have coded it Su1 till I get an ID.
Schlumbergera NOID
Pereskiopsis porterii(?)
NBG's:
Aloe arborescens
Aloe vera
Jade - Crassula ovata
The grafting attempt of a very small Su1 scion to O. robusta, failed.
Cheers
