Hi,
My local store has dozens of Ferocactus Chrysacanthus Rubrispinus ($4 each - is it cheap? 5cm-7cm diameter)
Is it possible to graft on it? I want to graft some Ariocarpus seedlings, and variagata
I found on Internet only references to Ferocactus Glaucescens which looks on pictures very similar to F. Chrysacanthus
Thanks,
