The maypop fruit is ripe when it turns from "Kermit the Frog" green to light green to yellow-orange in color. A better indication of a ripe maypop is a somewhat wrinkly skin whereas the unripe maypop fruit will have a firm, tight feel. Upon splitting the fruit you will see numerous seeds coated in a translucent goo while the inside of the skin will have a thick layer of white pulp. Suck the goo off the seeds like you were eating a pomegranate. The white pulp inside the skin is scrapped off with a spoon and eaten. Roasted seeds of these maypops are considered to be a wonderful snack in Puerto Rico.

Wild passion vines are uncommon in Texas so refrain from harvesting many the low-nutritional value fruit unless you find a vine really covered in fruit. These vines seem to produce a lot of fruit the year after a drought.

Tea made from the dried leaves and stem of the passionvine contain alkaloids with a sedative effect on humans. This tea can be purchased over the counter as a "sleepy time" the United States. Passionvines can quickly grow to cover a large area so harvesting young leaves and stems for use in tea will help keep the vine in check. As with any medicinal tea, I don't recommend drinking it more than 2-3 cups per week. They flowers can also be used for tea but they lack the sedative effect and you also lose the fruit from that flower.
