Comments: This is a twining vine that produces clusters of blue flowers or white flowers depending on the cultivar. Flowers have similar characteristics to morning glory blooms. The foliage is somewhat leathery. In warm climates this vine is evergreen and may need some pruning to keep it in bounds. This makes an excellent vine for landscape structures like arbors and trellises.
