Purple Passionflower (Passiflora incarnata) or "Maypop" - so called for its popping sound when crushed or its production of flowers and fruit in May - is a vining perennial that produces abundant flowers and foliage that are typically used for tea. The green fruits are edible (albeit not as prodigious as more the fruit oriented Passiflora edulis). This is the cold hardiest of the Passiflora genus, good for climates that have colder winters, and also can survive drought and extreme weather conditions.
Plants can be difficult to start. Reference the Planting Details below for further information.
