Growth
Passiflora quadrangularis is a tropical perennial evergreen that can grow to a maximum height of 15 metres (49 feet) by 5 metres (16 feet) wide. Giant Granadilla thrives in warm temperatures and moist nutrient-dense soils. However, if protected while they are seedlings, established plants can flower and fruit in temperate climates and will tolerate light frosts.
Giant Granadilla leaves are alternate, broad-ovate and can be as large as 20cm (8 inches) long by 15cm (6 inches) wide. Plants grow quickly in warm, moist conditions in full sun with soil that is well-drained. The ideal temperatures range from 20-30°C / 68-86°F during the day and young plants should be protected if temperatures drop below 8°C / 45°F.
It is recommended in colder climates to grow young Giant Granadilla plants in pots for the first full season and then transplant after the last frost in the second season. During the first season, they will require a trellis or similar to climb on and to prune off any flowers to encourage plant growth and to avoid any late Autumn damage.
In tropical conditions, Giant Granadilla can start producing fruit within the first growing season but in temperate climates usually takes between 18-24 months.
