Pint plant passion vine Passiflora subpeltata in a pearl white color. This vine produced hundreds of these blossoms during this past summer and give off a lightly perfumed scent that fills the yard when in full bloom. The vine grew to about 20 feet and was pretty much pest free. The caterpillars did not seem to want to eat this one as much as some of my others. This vines is foliage hardy in zones 9 and higher, although it will come back from the roots when the weather warms up if damaged by hard frosts.
