Borage or Forget-me-not family, includes a variety of shrubs, trees, and herbs, totaling about 2,000 species in 146 genera found worldwide.
Most though not all members of this family have hairy leaves. The coarse character of the hairs is due to Silicon dioxide and Calcium carbonate. In some species, Anthocyanins cause the flowers to change their color from red to blue when aging. This is likely used as a signal to pollinators that these old flowers are depleted of pollen and nectar.
