Sp. Pl.2: 958. 1753
Phenology: Flowering (Mar–)Jun–Sep(–Oct).
Habitat: Mesic, open woodlands and forest margins, 0–600(–1100) m
Perhaps the most widespread species of the genus endemic in the flora area, Passiflora lutea is probably becoming rarer at its geographic limits because of habitat loss. It is absent from southernmost Texas, and is therefore not sympatric with the similar P. filipes.
Passiflora lutea is our only native species, and one of very few in the genus, that has hypogeal seed germination. It is also extensively rhizomatous, forming rhizomes even as small seedlings. Very cold-hardy, it is able to thrive in cultivation far north of its natural range. The plants are shade-tolerant, but those growing in the open can occasionally form dense masses. The leaves often turn bright yellow in autumn.
