Passiflora incarnata bears flavorful fruits consumed by past and present pe
oples, and this plant deserves greater use as a fruit crop. Native to south
eastern North America, it is an herbaceous perennial vine which flowers and
fruits over much of the growing season. P. incarnata is self-incompatible
and usually pollinated by carpenter bees (Xylocopa spp.). Plants are functi
onally andromonoecious, and low resource status favors male flower producti
on and thus reduces fruit set. The fruits contain many seeds, each surround
ed by art aril holding edible juice, and this juice can be consumed fresh o
r used in processed products. Because it is a minor agricultural weed, P in
carnata should not be introduced into regions where it may naturalize. Poly
ploid hybrids of P. incarnata and the subtropical and tropical passionfruit
, P. edulis, are also potential temperate fruit crops. Future research on P
. incarnata should evaluate intraspecific genetic variation and performance
in cultivation.
