Hi all, its great to meet some others who are interested in growing plumerias from seed.
... I am an addict.
It is mid-winter here in New Zealand at the moment but that doesn't slow me down as I grow them all year round, indoors.
re the question above, most of my seeds start to sprout from 3 days onwards, till about 3 weeks. But only recently I had some sprout after a whole month, was Very surprised as this is most unusual. I suspect these were a little old but may have let them dry out a little too much.
Those Celadine seedlings sound very exciting, and from your own tree.
do keep us posted.
