USDA Symbol: pate9
USDA Native Status: L48 (N)
A vine with tendrils in leaf axils and bizarre, greenish flowers.
Unlike this species, which has evolutionarily lost its petals, most Passiflora have 10 petal-like parts; the common name passionflower relates to the resemblance of these flower parts to aspects of the Crucifixion story. The 10 petal-like parts represent the disciples, excluding Peter and Judas; the five stamens, the wounds Jesus received; the knob-like stigmas, the nails; and the fringed corona, the crown of thorns. There are several Passiflora species in the Southwest.
