You can do both but I'd definitely get cuttings. You'll be waiting 3+ years for blooms from plants started from seed. You also won't know what color/shape the flowers will be on seed grown plants. If you look through the forum you'll find reliable nurseries and Ebay sellers. You might want to spend a bit more and buy rooted plants. Being in FL you can probably find plumerias at Home Depot or a local nursery.

i have looked at Home Depot and local nurseries, and no one has any.

But I will keep looking.
Thank you

Two of the best in my opinion:

Florida Colors Nursery grafted plants(they have roots) in Homestead Fl.

Maui Plumeria Gardens in Hawai'i www.mauiplumeriagardens.com cuttings(no roots) & grafted &seeds. Also in Florida: Brad's Buds and Blooms,I believe are in Orlando or Geneva, Fl. that's 3 great sources, Good Luck and Oh they are Addictive, so watch out!

I second trojanfan's suggestions. Brad's is in Casselberry, FL.

I've also bought from Ebay but some people are wary of it. It definitely helps to know the reputable sellers. Otherwise you are taking your chances.

The Home Depot's around here don't sell plumies.

For Home Depot, I think you need to catch them at the right time, which is usually in the mid-summer in my area is when I see them. They come and go quick sometimes. And you might even find 1 gallon size plants in the florist stall in your supermarket, depends.

Carolyn, correction to my previous post:

Maui Plumeria Gardens sells Cuttings, rooted plumeria and seeds.
