Purple passion fruit (Passiflora
edulis Sim.) and
yellow passion fruit (P. edulis
f. flavicarpa Deg.) should more
correctly be referred to as “passionflower
fruit,” but the trade
more commonly uses “passion
fruit.” Passion fruit is often referred
to as “lilikoi” in Hawai‘i.
Hybrids of the two subspecies
freely form, showing characteristics
that combine those of the
two parents. A tough outer skin
surrounds a fleshy, acidic yellow
pericarp and aril surrounding
small, edible black seeds (Pruthi
1963, Anon. 2004, Paull and Duarte 2012).
