PP26698 EU43672 So lovely with its numerous upright spikes of medium sized purple flowers. Very elegant and free flowering. Loved by hummingbirds. 'Cha Cha Purple' has a most enchanting shade of wine-purple flowers; neither garish nor subtle – just right. Strong enough to stand up to contrasting colors, yet a good blender and most certainly a great garden performer. 'Cha Cha Purple' will enliven any garden space.
