Passiflora edulis forma flavicarpa 'Panama Red'

Passiflora edulis forma flavicarpa ‘Panama Red’

Passiflora edulis forma flavicarpa ‘Panam Red’ is a selection of Passiflora edulis forma flavicarpa with big dark red to purple fruit.

It is a selection developed in Australia where it is widely grown commercially. It has a good resistance to Fusarium.

Since it’s a selection and not a hybrid, it can be grown from seeds harvested from fruit.

It is only slightly frost resistant hardy and must be treated as an orangery plant: grow in a pot and overwinter indoors, protected from frost.

This is a very fast grower that can produce 100 flowers and fruit in one season.

Description:

Passiflora edulis fo. flavicarpa ‘Panama Red’ is a vine whose stems can grow to over 8 m long. The stems are brownish green and solid. They climb any support with tendrils.

The leaves have serrated edges and are darker green than those of fo. edulis, lobed to (often not lobed in young plants), shiny and 5-25 cm wide.

The flowers are 6-9 cm in diameter, a little bigger than those of fo. edulis. Sepals are white, oblong, up to 3,3 cm long and 1 cm wide. Petals are white, oblong, up to 3 cm long and 0.8 cm wide. The corona consists of four or five rows of filaments which are dark purple to black in the lower half and white and tortuous in the upper half. Fo. flavicarpa is not self-pollinating, unlike the fo. edulis, and therefore needs cross pollination to form fruit.

Fruit is dark red to purple with prominent lenticels, spherical to oblong, are 5-12 cm long and 4-8 cm wide, with a thick, leathery skin. They contain many shiny brown seeds which measure 3-4 mm. The taste is similar to of Passiflora edulis fo. edulis.

Usage:

The fruits are eaten fresh or used in drinks, candies, sorbets and desserts.

Overwintering:

Overwintering frost free, in a room with minimum 13 °C. When the temperature is about 15 °C and the danger of frost has passed, it can be brought outdoors again.
