3-7 years for Passiflora edulis under commercial cultivation.
Evergreen but frost-deciduous.
An elaborate structure, 3-4" wide, consisting of three stigmatas above (female),
five stamens below (pollen-bearing male), many dozen filaments, 10 petals and five green sepals underneath.
Each flower lasts only one or two days.
Passiflora edulis has yellow-green stigmatas and stamens, purple and white filaments and white petals.
'Incense' is fragrant, has white stigmata and stamens, purple filaments and purple petals.
Blue Crown is fragrant, has purple stigmatas, yellow-green stamens, white and blue filaments, and
Passiflora edulis: mid-spring into fall and year-round in some locations;
'Incense': mid-spring through summer; Blue Crown: mid-spring to early summer.
Blooming starts further into summer for northern locations.
Yes except for 'Incense' which needs cross pollination from a second plant.
It may be necessary to hand pollinate any of these species if bees do not find the flowers. The best time
to hand pollinate is about 10am in the morning. Clip off one of the five stamens and rub the yellow side
on the end of each of the three stigmatas.
Years before fruiting:
1-1/2 to 2.
Round or ovoid, 1-1/2" to 3" wide, a smooth, waxy, leathery rind. Passiflora edulis fruit
are purple when ripe. The rind contains aromatic, membranous sacs filled with orange-colored,
uniquely flavorful pulpy juice and many small hard, dark, edible seeds.
'Incense' has flavorful, yellow fruit, edible gelatinous pulp and dark seeds.
Blue Crown has orange fruit with soft, sweet red pulp and seeds that can be mixed with other fruit or juice
for an exotic flavor.
Months for fruit to ripen:
2-3. Passiflora edulis is ripe when ready to fall from the vine.
'Incense' is ripe when slightly dented or wrinkled. Blue Crown is ripe when fully orange.
Storage after harvest:
Fruit continue to ripen after harvest and can be refrigerated in sealed
plastic bags up to 2 weeks.
Green, palmate with three lobes on Passiflora edulis, three or five lobes on 'Incense'
and five fingers on Blue Crown.
The vine climbs using tendrils. Stems are herbaceous at first, then become woody with age,
except in regions with winter freezes where they die to the ground and come back from their roots.
Shallow, spread by root suckers, aggressive in moist soils in warm locations.
Passiflora edulis is sometimes grafted onto Passiflora edulis flavicarpa (Yellow Passionfruit) rootstock,
which better withstands soil diseases.
