Here is a link that contains several articles about growing breadfruit. Be aware, though, that growing breadfruit from seed won't be same as parent tree. It is usually propagated through root cuttings or shoots.

As to buying the seeds, we are not a retail establishment and do not sell products. I would check with reputable online seed sellers or inquire at a local nursery.
