A silvery white cast, sometimes called stippling, is general the result of spidermites feeding on the undersides of the leaves. Examine the leaves, especially the undersides, for tiny spidermites (look like specks of pepper) and for their webbing where the leaf meets the stem. Spidermites like dry, dusty places so you can often discourage them by spraying off your plants, especially the undersides of the leaves, with water from the hose. Or, you can use an insecticidal soap to control the pests. Be sure to apply according to label directions. Good luck with your verbena.
