Species of Note
for hot, dry climates:
Passiflora edulis 'Frederick' - grown commercially for its juice
P. incarnata x cincinnata 'Incense' - an ornamental that
needs hand pollination to fruit
P. caerulea: Blue Crown - a fruiting ornamental.
An elaborate structure, 3-4" wide, consisting of three stigmatas
(female), five stamens (pollen-bearing male), many dozen filaments,
10 petals and five green sepals underneath.
'Frederick' has yellow-green stigmatas, purple and white filaments and
'Incense' is fragrant, has white stigmata and stamens, wavy purple filaments
and purple petals.
Blue Crown is fragrant, has purple stigmatas, yellow-green stamens,
white and blue filaments, and white petals. Each flower lasts only one or two days.
'Frederick': mid-spring into fall and year-round in some locations,
'Incense': mid-spring through summer, Blue Crown: mid-spring to early summer.
Bloom start is further into summer for northern locations.
Yes except for 'Incense' which needs hand pollination
using cross pollination from a second plant.
Years before fruiting:
1-1/2 to 2.
Round or ovoid, 1-1/2 to 3" wide, a smooth, waxy, leathery rind.
'Frederick' has purple fruit. 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. 'Frederick' is ripe when ready to fall
from 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 'Frederick', three or five
lobes on 'Incense' and five fingers on Blue Crown.
Climbs using tendrils. Herbaceous at first, then becomes woody
with age, except in regions with winter freezes where it will die to the
ground and come back from its roots.
Shallow, spreads by root suckers. Aggressive in moist soils in
warm locations. 'Frederick' is sometimes grafted onto Passiflora
edulis flavicarpa: Yellow Passionfruit, which better withstands soil diseases.
Attracts bees, butterflies and hummingbirds. A caterpillar
host for several species of butterflies including the Gulf Fritillary.
Birds and mammals eat the fruit.
Toxic / Danger:
All parts poisonous except ripe fruit.
'Frederick' and Blue Crown - South America,
