Whether you’re looking for a plant that produces edible passion fruit or one that simply adds a splash of color to your garden, there’s a passion flower variety to suit your needs.
Overview of Passion Flower Varieties
The Passiflora genus is primarily composed of species native to tropical and subtropical regions of the Americas. These plants typically grow as understory vines in rainforests, with shallow root systems that allow them to thrive in a variety of conditions. The flowers are the true highlight of passion vines, often displaying intricate patterns and vivid colors. While many species are grown solely for their ornamental value, some varieties also produce the well-known passion fruit.
Passionfruit-Producing Varieties
Among the many species of Passiflora, Passiflora edulis Sims is the most famous for producing passionfruit. This species is unique in that it includes two distinct forms: the standard purple passionfruit and the yellow passionfruit, known botanically as Passiflora edulis f. flavicarpa Deg. Both varieties yield small, oval fruits with a juicy, fragrant orange pulp surrounding small black seeds. These fruits are popular for their sweet-tart flavor and are often used in beverages, desserts, and sauces.
Standout Passion Flower Varieties
In addition to Passiflora edulis, several other passion flower varieties are popular among gardeners for their striking flowers and adaptability.
- Maypop (Passiflora incarnata): Native to Texas, this variety is also known as “Maypop” due to the distinctive popping sound the fruits make when stepped on. It is one of the hardiest passion flower types, easily grown from seed and tolerant of cooler climates.
- Passiflora alatocaerulea: This hybrid variety is prized for its 4-inch flowers, which are commonly used in perfume production. If fragrance is a priority in your garden, this is an excellent choice. However, it may require frost protection in winter.
