Plant in pint pot of Passiflora Lavender Lady, also known as Passiflora Amethyst, Star of Mikan, Passiflora violacea, Passiflora amethystina, and Passiflora onychina. Passiflora Amethyst has bright lavender petals surrounded by bright blue filaments in a ring of navy blue. This is my most reliable passionvine for blossom production. This vine produced hundreds of these blossoms all year long, and I kept it in the greenhouse over the winter. Passiflora Amethyst gives off a lightly perfumed scent that fills the yard when in full bloom. The vine grew to about 30 feet. USDA Hardiness Zones 7 to 12.
