Easy to grow background plant, with large long blooming sprays of little purple flowers atop short basal growth; good for fresh cut flower arrangements. Truly a great butterfly plant. Self sows easily, so remove flowers when they are spent. Grows well in very dry conditions, and in afternoon shade in hottest climates. Grow it in the background, since the lower growth is not very attractive. Plant Phygelius 'Moonraker' and Coprosma 'Black Cloud' in front to hide the lower growth.
