Myosotis sylvatica

Myosotis sylvatica, the wood forget-me-not or woodland forget-me-not,^[1] is a species of flowering plant in the family Boraginaceae, native to Europe. This spring-flowering plant and its cultivars, typically with blue flowers, are the familiar forget-me-nots of gardens.

Upright, to 50 cm; softly hairy, with hairs at more-or-less right-angles to the main stem.

Flowers sky-blue, to 6–10 mm across, flat in profile; tube with hooked hairs; April–July.^[3]

sepal

Mature fruit dark brown, shiny.

Mature on spreading stalks longer than sepal tube; calyx teeth spreading to expose the ripe fruit.

calyx

Basal leaves stalked, in a rosette; upper leaves not stalked.

Generally found in woods, scree and rock ledges; common throughout the British Isles.

It is a short-lived herbaceous perennial plant, growing to 12–30 cm (5–12 in) tall by 15 cm (6 in) wide, with hairy leaves and a profusion of flowers with petals longer than their tube, pink in bud then opening disc-shaped, intensely sky-blue with yellow centres in spring.

Stace (2011)^[2] describes this plant as having the following characteristics:

'Blue Basket', a taller variety with deeper blue flowers

'Music', erect and large flowered

'Pompadour', compact, ball-shaped with large rose-pink flowers

'Snowball', white flowers

'Ultramarine', dwarf with very deep blue flowers

'Victoria Rose', bright pink flowers

Widely cultivated throughout the temperate world, it is particularly associated with spring bedding schemes involving other spring-flowering subjects, notably daffodils, tulips, wallflowers, and primulas. Typically seeds are sown one year to flower the next. Though short-lived, plants readily self-seed in favourable situations. Plants maintain leaf growth throughout winter.

M. sylvatica is also a parent of numerous cultivars in shades of pink, blue and white.^[4] The cultivars 'Bluesylva'^[5] and the compact 'Blue Ball'^[6] have gained the Royal Horticultural Society's Award of Garden Merit.^[7]

Other cultivars include:

British Isles[edit]

As plants readily self-seed, it is often difficult to establish whether plants seen in the wild are in fact garden escapes.

It is widespread in England, Wales, and the Isle of Man, although less frequent further north. It can be found along much of the east coast of Scotland and areas in the South West, although missing from most of the Highlands, Orkney, Shetland, and the Outer Hebrides. In Ireland it is mostly found in Northern Ireland, although there are a few spots in the Republic of Ireland.^[8]
