Description and Cultural Plant Tips

This is a twining or shrubby growing vine with delicate foliage and spikes of small, pea-shaped, violet-blue flowers that grow in long clusters. These vines can be trained as screens on trellises, walls or fences. They can also be used as ground covers if pegged down.

Plant slightly above soil grade in well-drained, light soil. Mulch well after planting to keep soil moist. This vine is considered to be drought tolerant once established. Do not overwater. Can be grown in full sun in coastal Marin but does best with some afternoon shade in the hotter parts of Marin. Needs support if grown as a vine. Cut back after blooming to control size and stem tangling. If you are in an area of Marin that drops below 24 degrees, this plant will need to be protected.

Attracts bees and other nectar loving insects.

This plant is susceptible to spider mites and nematodes. See the UC IPM for treatment choices.
