The flowers are a deep blue-violet that positively sings against natural wood or stonework. Smaller clusters appear lightly but steadily after pruning.
A genus of deciduous vines whose lovely, fragrant flowers and almost overwhelming vigor make them useful in a wide variety of settings. Plants grow rapidly to 30ft and completely bury any structure they are allowed to annex. This rampant growth is easily controlled (and flowering is encouraged) by regular pruning. Plants thrive in full sun (or partial shade in the South) and average soil.
