I bought indivisa seeds from rare palm seeds, sowed them in Feb and so far big fat nothing
I've tried them in cool and hot conditions, but no sign of life.
not sure about using rare palm seeds for anything else but agave seeds. I bought:
agave gentryi & ovatifolia, 90% germination
indivisa 0%
Chamaedorea radicalis 10%
Macrozamia miquelii 40%
