hmm, well i agree that, flowering caapi has to do with the photo period.
my garden is right bang at, the tropic of capricorn and none, of my banisteriopsis have ever flowered.
i might add that, the caapi going round 20 years ago, was proly less, eager to flower than, a recent plant making round's, which might be called "cielo".
cielo might flower more easely than the old strain...
sab member, have posted here, pics of there caapi flowers!!
