Skyblue clustervine is an evergreen, twining vine that produces many small but showy flowers. Bloom colors range from sky blue to pinkish-lavendar, all with white "throats." Leaves are deeply veined and oval- to cordate-shaped.

Also known as Key West morning-glory, skyblue clustervine occurs naturally in coastal hammocks and along wetlands in South Florida. It typically flowers in winter, but is known to bloom from early fall through late spring.

Skyblue clustervine is a member of the morning glory family, so flowers open in the morning. It attracts a variety of pollinators, including the nessus sphinx (Amphion floridensis), tantalus sphinx (Aellopus tantalus) and tersa sphinx (Xylophanes tersa) moths, which pollinate the flowers at dusk. 

It is an endangered species in Florida.

Hardiness: South Florida (Zones 10-11)
Soil: Moist but well-drained sand or lime rock
Exposure: Full sun to minimal shade
