Seeds of passion vine Passiflora byroniodes, Cupped passionvine, root hardy to zone 9. It is native to Arizona. This vine produced hundreds of these beautiful blossoms during this past summer and give off a very light perfumed scent that fills the yard when in full bloom. The vine grew to about 10′ and was pretty much pest free. This vines is foliage hardy in zones 9 and higher, I keep mine in the ground and protect it in the winter months with a very light mulch.
