Anna. Hetty is one of the expert Plumeria growers here on ATP and with her help, I started my first two seedlings in Dec. 2013. Those two seedlings are now 3'+ and though I have been assured I won't see blooms this year, I am still hopeful. I started another 16 (total) seedlings in the spring/summer, 2014, from April through June. The April ones are about 18" tall and the others are 8-16" tall. Hetty told me to keep them growing through the winter months and I have them all in a greenhouse.
All my seeds were donated and thus don't know how old/viable they were. I experimented and tried to germinate them in four ways. In my experience, you can ask six people who have germinated Plumeria seeds and you will get six ways to do this. Since I did not know the viability of the seeds, I don't know whether one way was any better than another. In any case, I only had perhaps 25% of my seeds germinate and lost a few of the tiny plants even after germination. The are very fragile things when they first germinate and I just wasn't careful enough with them when transferring them to potting soil.
Speaking of Hetty, she doesn't brag about it, but she has had (I think) two of her seedlings named and were accepted by the PSA. How great is that!? Basically, when you grow from seed (unless it is done under careful laboratory conditions) your plants will be "new" plants. Even if you knew the "parents", the flowers would be different than either parent plant. That's why you can name those new seedlings. Hetty will correct me if I am wrong about this.
