Description

This semi-evergreen to evergreen, woody, twining vine is easy to grow and prefers well-drained, humusy soil in full sun. Mulch the plant to help keep the roots cool and moist. Its star-shaped flowers cascade down the vine and come in blue, pinks, and purple. It blooms on previous season's growth (Group 1), so prune after flowering. This plant's vanilla fragrance fills the air and makes it a great addition to a patio or walkway where the fragrance can be enjoyed.
