Passiflora caerulea

Passiflora caerulea
Setting buds in early March

Common name blue crown passion flower
Family passifloraceae
Life cycle perennial (Z7-10)
Flowers blue/white
Size vine to 30'
Light sun
Cultural notes well drained soil; drought tolerant

Blue passion flower is relatively hardy (although ours came with a tag that said hardy to 32F, most other sources rate it murch hardier, to 10F or so), with the large blue-and-white flowers typical of the genus. They need well drained soil and develop deep root systems that provide drought tolerance and root hardiness (hopefully, ours will survive our typical Houston clay amended with some organic matter). Flowers on new growth. Host plant for several butterfly species. Native to South America.

This plant used to grow in our garden, but it slipped away...
