- History & LoreHistory:This group of shrubs is classified in the borage family, Boraginaceae. It was named by German botanist, August Grisebach, 1814-1879, who is most noted as author of Flora of the British West Indian Islands. This genus contains just seven species of low hairy shrubs from Europe, North Africa, and Asia Minor. This species is found in southern Europe and Morocco. It was formerly known as Lithospermum diffusum by Mariano Lagasca y Segura, 1776-1839 of Spain, and many contemporary references still consider this a synonym for L. diffusa. This and other plants were separated from that genus and reclassified in a whole new genus created for them by botanist Ivan Murray Johnston of the Arnold Arboretum at Harvard University, Massachusetts.
