Passiflora ‘Cassiopeia’ has survived with very little leaf loss down to 20.9 degrees F with no protection. With Passiflora loefgrenii, Passiflora caerulea, and Passiflora caerulea ‘Constance Elliott’, it is an extremely hardy plant. It is a free flowering plant in summer, and thankfully kept much of the P. loefgrenii color. It has large flowers and viable pollen.
