The name 'passion' is a reference to the crucifixion of Jesus of Nazareth. Parts of the flower are said to resemble instruments used during the crucifixion. Given the proper support this plant makes an excellent climbing vine hedge.

Night blooming, fragrant.

This is an endangered species. Please do not steal from the wild. Mostly grown as a curiosity as it is an early morning bloomer and nearly invisible when not in flower. Grow in a wildflower garden.

Noted for fragrance. Casual shade garden. It spreads, so eventually acts as a groundcover.

The genus name honors the English botanist William Vernon, who did fieldwork in North America. Back of a moist wildflower garden. Can also use on the edges of natural or created wetlands and streams.

Shade tree. Relatively conical or oval in form. Straight trunk.

Depending on the weather, this may be either an annual or perennial in Florida. Informal gardens in wet sites.

The short lived bloom opens before sunrise and is most beautiful from just before dawn till about mid-morning when it fully opens. By night fall it will have wilted.
