I recently bought one from a native nursery. I saw a picture of it on the internet and had to have it. Was so happy when I found it, but it hasn't had any flowers as of yet. I can't wait!!!!!!

Absolutely delightful, delicate climber with stunning violet blue to blue flowers. Even though it has small, short lived flowers there is a constant succession of flowers from the small clusters of buds. The flowers are easily seen from some distance. So intense is the colour and the numbers of flowers during the main flowering season the vine is more or less completely covered in blue. Flowers open facing the sun in the early morning and are gone by midday. Like magic the next morning they make another mass appearance. On overcast rainy days the flowers don't open but generally appear in the dry, sunny season in the tropics. Worth remembering that the vine only flowers facing the sun and in the morning.

Jacquemontia pentanthos, sky blue clustervine, is native to the Florida Keys. It prefers a sunny location. It is easily grown from cuttings. I believe that the plant is protected in Florida, so do not collect any wild-growing material. It never produces heavy, woody stems and is an excellent vine for a chainlink type of fence.

Skyblue cluster vine is a fast growing, twining vine, with stems to 6 feet or more in length. A beautiful shade of blue, blooming most of the year in S Florida, but much stronger in fall and early winter months.

Provides food for birds. Nectar plant for nessus sphinx (Amphion floridensis), tantalus sphinx (Aellopus tantalus) and tersa sphinx (Xylophanes tersa) moths.

Skyblue clustervine is widely planted outside of its historic range and is escaping from cultivation. Also, it can be fairly aggressive in cultivation.

It is listed as endangered by the State of Florida.
