FORGET-ME-NOT, called also scorpion-grass, the name popularly applied to the small annual or perennial herbs forming the genus Myosotis of the family Boraginaceae, from the Greek Ain, a mouse, and o vs, an ear, on account of the shape of the leaves. The genus is represented in Europe, north Asia, North America and Australia, and is characterized by oblong or linear stem-leaves, flowers in terminal scorpioid cymes, small blue, pink or white flowers, a five-cleft persistent calyx, a salver- or funnel shaped corolla, having its mouth closed by five short scales, and hard, smooth, shining nutlets. The common forget-me-not, M. scorpioides, native to Europe and Asia, found in Great Britain, and naturalized in North America is perennial; it grows to a height of 6 to 18 in., with rootstock creeping, stem clothed with lax spreading hairs, leaves light green, and somewhat shining, buds pink, becoming blue as they expand, and corolla rotate, and bright blue with a yellow centre. The forget-me-not, a favourite with poets, and the symbol of constancy, is a frequent ornament of brooks, rivers and ditches, and, according to an old German tradition, received its name from the last words of a knight who was drowned in the attempt to procure the flower for his lady. It attains its greatest perfection under cultivation, and, as it flowers throughout the summer, is used with good effect for gar den borders. Various European species are widely cultivated, especially M. scorpioides, M. azorica and M. sylvatica. In M. versicolor the flowers are yellow when first open and change gen erally to a dull blue. Of the species in cultivation, M. dissitiflora, with large handsome abundant sky-blue flowers, is one of the best and earliest, flowering from February onwards. M. rupicola, or M. alpestris, 2 to 3 in., intense blue, is a fine rock plant, pre ferring shady situations and gritty soil.
