About
Passiflora lutea, commonly known as yellow passionflower, is a flowering perennial vine in the family Passifloraceae, native to the central and eastern United States. The vine has three-lobed leaves and small, yellowish-green, fringed flowers that appear in the summer, followed by green fruit that turn almost black at maturity. It grows in moist to wet habitats.
It is also a host plant for the passionflower flea beetle (Disonycha discoidea).
Where it grows
P. lutea is native in the United States from Pennsylvania west to Kansas, and south to Florida and Texas. It is the northernmost species of Passiflora, occurring slightly further north than P. incarnata, and tolerant of winter temperatures down to −15 °C, and even −30 °C for short periods.
