hi happyhana,
haven't tried Passiflora laurifolia that i know of. : >)
i believe that bell apple is indigenous to the virgin islands but i don't know if i've ever heard anyone mention ''water lemon'' or ''jamaican honeysuckle''.
i'll have to ask around. thanks.
from the same top tropical page linked above:
''Another similar species - Passiflora laurifolia, commonly known as the Water Lemon, Jamaican Honeysuckle and Orange Lilikoi. The fruit is very sweet and the plant is rare in cultivation. It is native to tropical Americas. It is not yet widely known outside those regions. The fruits are eaten fresh, or used in drinks and beverages.
The fruit is medium-sized, ovoid in shape, about 2 in long, with a green or deep orange skin and white-yellow, extremely juicy pulp. The water lemon has an excellent mild, perfumed taste, without the tartness of the common Passionfruit. It grows on a vigorous vine up to 30 feet long. Growing better in slightly humid climates, the vine is not particular about soil or water requirements, other than liking ground moisture year-round. As a tropical species, it will not tolerate frost.
It is almost always grown from seeds, but can be propagated by cuttings.''
best,
mike
