celt33040, you asked about the care & planting of the Ylang Ylang seeds. I've grown many Ylang Ylang trees from seed though they have all been the normal, large Cananga Odorata, not the dwarf var Fruiticosa. I collected the seeds, cleaned and dried them. I either kept them for a while or planted them immediately. (depended if I was exchanging them or not). Either way, they take a longggg time to germinate. About 4+ months. The growth of the tree is very slow in its early stage. My present seedlings are about 2.5 years old and are hardly 2 feet. However, they are still in a very large pot and I'm about to plant them out. Once in the soil, they do speed up and the ones that are now about 15' and blooming are about 5 years old. They are more floriferous as well as taller than the one I bought! However, despite the vast number of flowers they all have, none are seeding as yet. If you do plant seeds, be patient.
Actually, there is a better way to propogate this lovely fragrant tree. I'm sure yours will be ok with this as well. AIRLAYERING. One of the best reasons to air-layer is that the plant does not start out as a 'seedling' but as a daughter of the mother plant. Meaning that if the mother is flowering, the daughter too will flower just as the mother does. Starting out with a seedling, one has to wait till its mature enough to produce flowers. Try airlayering and I'm confident you'll never look back. For example: my brunfelsias take 6 weeks to root and bloom within a very short time once they are established in the soil.

Just a note here: I don't cut a wedge as indicated in some of the tutorials, but immediately powder and wrap the wound as indicated. Maybe cutting a wedge would produce more roots, but I can't comment as I've never done it.
Just for fun, do try airlayering!
