Passifloraceae (Passion-Flower Family)



Purple passion-flower is an herbaceous vine, up to 25 ft. long, that climbs with axillary tendrils or sprawls along the ground. Intricate, 3 in., lavender flower are short-stalked from leaf axils. The petals and sepals subtend a fringe of wavy or crimped, hair-like segments. The pistil and stamens are also showy. Three-lobed, deciduous leaves are dark-green above and whitish below. The fruit is a large, orange-yellow berry with edible pulp. Like some other passion vines, Maypop spreads by root suckers.

This unusual flower is widely distributed in the Southeast, especially from Florida to Texas. The plants were given the name Passionflower or Passion vine because the floral parts were once said to represent aspects of the Christian crucifixion story, sometimes referred to as the Passion. The 10 petal-like parts represent Jesuss disciples, excluding Peter and Judas; the 5 stamens the wounds Jesus received; the knob-like stigmas the nails; the fringe the crown of thorns. The name Maypop comes from the hollow, yellow fruits that pop loudly when crushed. Yellow Passion Flower (P. lutea), a small yellow-flowered species, occurs from southeast Pennsylvania to Florida, west to Texas and Oklahoma, and north to Missouri, Illinois, and West Virginia.
