Forget-me-nots provide a delightful succession of tiny pure blue – or pink –, each with a white or yellow eye, from mid spring to early summer. They are used mainly for bedding with spring- , though they also make attractive long-lasting cut flowers – only when the sprigs are taken indoors is the neatness and delicate colouring of the tiny flowers fully appreciated. They are also useful plants for the front of mixed borders, wild gardens and shrubberies.
The varieties available all stem from Myosotis alpestris and M. syl-vatica and include the following: ‘Blue Ball’ forms compact ball-shaped plants just 15-20cm (6-8in) high, bearing indigo-blue flowers. It is an excellent edging variety. ‘Blue Bouquet’ is a tall variety, 38cm (15in) high, with sprays of large deep blue flowers. Useful for cutting and in bedding schemes. ‘Carmine King’ has rich pink flowers on compact plants and reaches 20cm (8in) high. ‘Compindi’, of compact habit and 15-20cm (6-8in) high, has deep blue flowers. ‘Rose Pink’ is a mid-pink variety.
The compact plants are just 15cm (6in) tall. ‘Royal Blue’ reaches 30cm (1ft) high and has loose sprays of indigo-blue flowers. It is one of the first varieties to bloom. ‘Spring Symphony Mixed’ is an early-flowering strain, with plants up to 20cm (8in) high and with white, rose-pink and ultramarine-blue flowers. Compact and good for edging.
For the best results, forget-me-nots should be raised as biennials. Sow the seeds in trays in early summer, then transplant to the flowering site in autumn, setting them 15cm (6in) apart. For the best results grow them in fertile well-drained but moisture retentive soil in partial shade, though ordinary garden soil in sun or shade is quite adequate.
Forget-me-nots self-seed and hybridize easily.
