In addition to using the ripened fruits, owners of Passiflora species can dry the leaves and flowers to brew a calming herbal tea. Despite its supportive value for wildlife, Passiflora lutea is seldom browsed by deer.

Site this delightful beauty in fertile, moist, well-drained soils in full sun to partial shade, mulching well the first fall while it establishes. Once settled in, Yellow Passionflower is hardy to –20°.
