Gardeners' Notes:

Positive amygirl On Feb 26, 2008, amygirl from Miami, FL wrote:

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.

Positive artcons On Nov 27, 2007, artcons from Fort Lauderdale, FL (Zone 10b) wrote:

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.
