MYOSOTIS FORGET-ME-NOT

"Although the fifty species of Myosotis occur throughout both northern and southern temperate regions, only a few European species have had a major impact on gardens. The widely cultivated bedding forget-me-nots with small blue flowers are derived from M. sylvatica and M. scorpioides, both native to Europe, and many cultivars are now available. A few Australasian species, with white or yellowish flowers, are cultivated in specialist collections." [Prance TCHP]

"Annual to perennial herb, glabrous to rough-hairy; roots generally fibrous. Stem: decumbent to erect. Leaf: basal generally oblong or oblanceolate; cauline generally linear to elliptic. Inflorescence: generally raceme-like cymes, coiled, in age ± open; bracts 0 (leaf-like). Flower: calyx lobes 5, tube hairs appressed to spreading, hooked at tip or not; corolla salverform or wide-funnel-shaped, generally blue, white, or yellow, appendages prominent or not; stamens included; style generally included. Fruit: nutlets generally 4, ± lens-shaped, smooth, shiny, each with raised outer margin, attachment scar adaxially, at base, small."
"50 species: temperate, boreal. (Greek: mouse ear, from leaf) Myosotis arvensis (L.) Hill reported from Orange Co., 1938, not persisting."

2 Open corolla commonly 6–10 mm wide; calyx lobes not more than one-third as long as the tube (common in woodlands to which it has escaped from cultivation, and also found in wet places) . . . . . . . . . . . . M. scorpioides forget-me-not (Europe)
1 Calyx with at least some hooked hairs
3 Corolla at first yellow, changing to blue . . . . . . . . . . M. discolor, pl. 167 yellow-and-blue scorpion grass (Europe)
3 Corolla blue or white from the beginning
4 Calyx slightly asymmetrical, 2 of the lobes longer than the other 3; corolla white . . . . . . . . . . M. verna white scorpion grass

Myosotis scorpioides - European forget-me-not

Myosotis scorpioides is an evergreen Perennial growing to 0.3 m (1ft) by 0.6 m (2ft in) at a fast rate.
It is hardy to zone (UK) 5. It is in leaf 12-Jan It is in flower from May to September, and the seeds ripen from Jul to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, flies, lepidoptera.
"Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist or wet soil and can grow in water." [PFAF]1

Cultivation

Propagation

Myosotis scorpioides; "Seed - sow outdoors in situ in late spring or early summer. Germination usually takes place within 2 - 4 weeks at 20°c. Division in spring[111]. Large divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer. Cuttings of young shoots, summer in a shady border[111]." [PFAF]1
