    Collected and introduced to Europe in 1794 by von Thunberg (1743-1828). Carl Peter von Thunberg, student of Linnaeus at Uppsala University in Sweden, made three trips to the Cape of Good Hope 1772-1775 where he collected about 1000 new species, Java and Ceylon (Sri Lanka) 1777 and 15 months in Japan where he befriended local doctors who gave him hundreds of plants new to Western horticulture.  He succeeded Linnaeus as professor of medicine and botany at Uppsala and King Gustav beknighted him.   Young Cape forget-me-not plants were eaten as a vegetable, Annals of the South African Museum, 1898.  Louise Beebe Wilder loved this plant, effusing, “One of the prettiest (blue annuals) is the Cape Forget-me-not.  Not one of its cerulean family boasts a purer blue and its summer-long period of bloom and indifference to drought make it a really valuable annual.  It has also a sturdy habit of growth and sowing its hardy seeds freely it does its best to become a permanent resident.”  Robinson called it “Remarkably fine…” The Garden 1873.  The name Anchusa from anchousa paint used on skin.

    The Japanese anemone introduced to cultivation in the West when Robert Fortune found them growing wild at a graveyard near Shanghai in 1844. Anemone ‘Honorine Jobert’ is a sport of a cross between Japanese anemone and A. vitifolia, introduced by Lady Amherst from Nepal in 1829.  This white sport appeared in the nursery of Messier Jobert at Verdun-sur-Meuse in 1851.  He propagated it and named it for his daughter, Honorine. The name Anemone is Greek for the wind, “so called, because the flower is supposed not to open, except the wind blows.” The Gardeners’ Dictionary, 1768.
