Silverbush, or Convolvulus cneorum is a mounding, densely foliaged evergreen plant native to north Africa, the Balkans and Italy. Its leaves are covered with silky, silver gray hairs that shine like chrome in good light. As if that were not enough it is pretty much covered with trumpet shaped 1.5 inch snow white blooms from late spring well into summer.
It works well as a container plant in cold climates and can be overwintered indoors in a bright sunny window. I will offer this caution, however. Experts I trust implicitly say this plant is no easier than Rosemary to grow indoors. So, gardeners in any hardiness zones north of 8 might want to consider this plant an annual.
