This shrub-like perennial offers elegant grey-green mounds of foliage and fragrant, orange-red flowers that age to a deep orchid purple creating a great bicolour effect. Long-blooming from spring through summer. Sheer lightly when flowering slows or when flower stems become too long. Rebloom will start shortly thereafter. Wallflowers have a reputation for being short-lived in Vancouver. For long-lived, compact specimens plant them in a hot, dry, sunny spot in the garden.
