As the name infers, the flowers of this plant open at night. Once the sun starts coming up, the flowers will begin to wilt. By night fall the flowers are spent. Can be grown as a groundcover but probably best welcomed into a multi-species planting where its flowers bring color to an planting of low greenery.

Its deeply divided leaves look somewhat like marijuana leaves(Cannabis spp.). Specimen plant in moist areas. There is also a white-flowered variant.
