Silver leaf is a flowering evergreen shrub with arching branches and woolly, silvery gray leaves. In summer, it bears solitary, bell-shaped rose-purple flowers an inch across.Silver leaf is a medium-sized shrub with a compact form, delicate silvery to gray-green leaves, and stunning displays of prolific purple blooms from summer into fall. It is sometimes called "barometer bush" because flowering is triggered by humidity or high soil moisture after rains.It is extremely drought and heat tolerant and maintenance-free once established. to thrive in a landscape, it must have full sun and very well-drained soil. Although watering in dry summer months will make it grow faster, over-watering or poor drainage will quickly kill it, and shade will promote leggy growth and less flowering.
