Also called Bush Clock Vine, this thunbergia is valued for its beautiful display of purple flowers all summer. The shape of this plant depends on how much it is pruned. It will form a creeping mound, if left untrimmed, or a low bushy shrub with regular light pruning. Perfect for planting around patios, foundations or among border plantings. The dense foliage makes a great low hedge row. Beautiful when planted in large patio containers. Photo courtesy of Master Tag.
