Passiflora miniata or Red Passionflower has the deepest red flowers of the genus Passiflora.
It is a fast growing vine that flowers all year round but especially during the summer.
Not hardy so must be grown in pots and wintered indoors in frost zones or grown as a houseplant. It is particularly suited to cover a pergola or trellis.
It was long confused with Passiflora coccinea and even cultivated under that name at Kew’s. It was only in 2006 that John Vanderplank classified it as a separate species. The difference is that P. miniata has 3 series of corona filaments, the outer serie being purple and the inner white, while P. coccinea has 2 series of white or pale pink filaments.
Passiflora miniata is a fast growing vine that clings with tendrils and grows up to 3-6 meters high. The stems are red to purple.
Leaves are ovate-oblong, 6-14 cm long and 3-7 cm wide, sub-cordate, shallowly serrated at the edge, green, glaucous or sparsely hairy above, rust-colored tomentose underneath.
The flower stalk is up to 8 cm long; bracts are oval and tough. Flowers are scarlet or red, bisexual, 5 sepals, 5 petals, recurved, with a central, short straight corona with 3 rows of filaments, the outer row is purple in color while the inner rows are white. There are 5 reddish stamens, fused into a tube around the ovary, with 5 linear, yellow green, oblong anthers.
The fruit is subglobose or ovoid, approximately 5 cm in diameter, orange or yellow with green spots. The seeds are surrounded by an edible aril.

Amazon region of Peru, Brazil, Colombia and Bolivia
Tropical Amazonian lowlands
USDA zone 10-12
Rich in humus and well drained
Sun, light. Blooms better with more light.
Keep the substrate moist, daily watering during the growth period
Provide abundant fertilizer: every 2 weeks during the growing season
May be pruned in spring to shape and limit its size.
Pruning also promotes flowering because the flowers appear on new growth.
Do not repot too often and do not use too large pots: Passiflora blooms usually better when it is in a narrow pot.
- proceed in spring or summer
- take cuttings from the top of the stems and make sure there is a knot with older wood present
- dip in cutting hormone (optional)
- put in light potting soil and moisten
- wrap the pot in a plastic bag to limit evaporation
- soak seeds 24 h in warm water
- plant in moist potting soil at 0.5 cm depth
- place the pot in a plastic bag to keep humidity
- 20-24 °C
