Recently IÂve bought a number of batches of plumeria seeds from "cuckooznest" on Ebay, and am getting prompt shipments and eighty to one hundred percent germination. No problems so far.

I too have bought plumeria seeds and have had good germination.Because I am new to plumerias I had great difficulty in removing the seed coats after germination and actually pulled a head off one little seedling.I now remove any sprouted seeds at once and holding them by the cotyledons find it easy to peel off the skins and replant into their little pots.They don't seem to mind!Better than be-heading them!

felixcat- I have used two needles after wetting the coat, slip the needles in and part to split the coat. Seedling growers. Just realize that the plumeria has a wide range of genes and your seeds may look nothing at all like the parent. Also, seedlings usually take from 3 years to 20 years to flower with the bulk blooming in three. However, you usually need to wait for three seasons to be sure a flower is correct as many first flowers are not true to the plant. As a rule, the whites produce a variety of whites, but the multi-colors are the best because you can get all sorts of sizes, shapes and colors. The Moragnes are excellent as the seedlings are little giants and they hold all the colors in their genes. Daisy Wilcox is also great because it is so big (mine had a 7" flower last year although most are 4-5") I would also recommend Gloria Schmidt and Cooktown Sunset if you can find their seeds.

Tdoddad. Thankyou for your information on the use of needles.I have done that sucessfully since and I do feel a bit like a brain surgeon!I am delighted to see how well the plumeria grow in your areas on the forum because here in the U.K. it does not get so hot for long spells(perhaps global warming will change that)We are not allowed to import except from the european union but I have found a supplier of rooted cuttings on e-bay who is in Belgium and have bought a few named ones which I am very pleased with.I am reading your forum to learn as much as I can.Thankyou.
