Hi, I collect and grow various Ipomoea.
I noticed that Ipomoea muricata 'Clove Bean' flowers automatically from seed regardless of the day length. However Ipomoea muricata 'Kaladana' does not flower until autumn when the days are short. I suspect these two might be distinct (cryptic) species, though they look very similar.
I have been growing most of my Ipomoea indoors because they tend to be short day flowering plants in my experience and I have repeatedly observed light interruptions in the night time cause flowering to stop in several species.
I've had Stictocardia bloom, indoors, in under 2 months from seed, though it did not set seed.
At present I have Ipomoea amnicola, Ipomoea aquatica and Ipomoea fistulosa flowering indoors and Ipomoea setosa developing fruit from blooms a few weeks back.
The only species I have seen yet that flowers automatically from seed, in a clockwork like manner, is Ipomoea muricata 'Clove Bean' which is a culinary selection that is traditionally eaten in India.
I am interested in learning about the experiences of others in regard to triggering flowering in Ipomoea .
