Unlike other Passiflora flower varieties, maypop fruit stays green and doesn’t turn red or purple, as it ripens it will lighten and might turn yellow. When it’s ripe it will get wrinkly and soft and will probably fall off the vine. The more ripe it is, the better the flavor. To eat the fruit, slice it open (or pull off the top at the stem) and scoop out the pulp covered seeds. Like pomegranates we eat the seeds and pulp, but I know some people prefer just the seeds.
