|Silver Queen is an evergreen shrub, with an upright habit and an umbrella shaped top. It can accept pruning to keep it smaller, or trained as a tree with it's attractive curving trunk. The leaves are oval-round, 1 to 2 inches long and have a glossy leathery texture, with dark green color and creamy white margins. This attractive plant seems like a great, inexpensive, substitute for the formal garden because of its heat, drought, and soil tolerance, but pest and disease problems seem to damper the possibilities. Watch for scale, thrips, or spider mites, as well as powdery mildew, where air is stagnant and humid. Locate in full sun to prevent mildew.
