This cultivar was discovered in the garden of James Van Remsen of Louisiana and was named and introduced by Salvia guru Richard Dufresne of North Carolina.

A crown of deep sapphire blue filaments create a striking contrast with the white petals and sepals that are held against the rich green foliage throughout the growing season. The Blue Crown Passionflower is a vigorous growing tropical vine and can easily reach 20' once well-established. This is also one of the most reliably cold hardy Passionvines with foliage remaining evergreen in the mildest 8B winters but dying back to the ground in severe winters and returning readily in spring. The Blue Crown Passionflower may spread somewhat by rhizomes but it is generally much more tame than the Maypop. Cross pollination may produce tropical tasting tangy fruit that surrounds the dark seeds inside.
