Position: full sun or partial shade Soil: well-drained, moderately fertile soil Rate of growth: average Flowering period: May and June Hardiness: fully hardy Luscious, lemon-scented, cornflower blue flowers with ruffled petals in May and June and sword-shaped, grey-green leaves, retained all year. This stately bearded iris looks lovely towards the front of a sunny, well- drained border among lavender or Russian sage. A popular, tall variety, it will need staking. Garden Care: Plant shallowly with the upper part of the rhizome sitting on the surface of the soil, incorporating a low nitrogen fertiliser in the planting hole.

Heuchera ‘Fire Chief (PBR)’ (coral bells) £3.99
Position: partial shade Soil: fertile, moist or well-drained soil Rate of growth: average Flowering period: June to August Hardiness: fully hardy Vibrant red foliage, which takes on a darker hue as it matures, is crowned with pink-flushed flowers from late spring to midsummer. The flowers attract bees and will last up to two weeks after being cut and added to fresh arrangements. Garden care: Remove tatty foliage in autumn. Lift and divide clumps every couple of years in early autumn and replant with the crown just above the surface of the soil. Apply a generous 5-7 cm (2-3 in) mulch of well-rotted organic matter around the crown of the plant in spring.

Agapanthus ‘Glen Avon’ (African lily) £3.99
Position: full sun Soil: fertile, moist, well-drained soil (or John Innes no.3 compost for containers) Rate of growth: average Flowering period: July to September Hardiness: half hardy (will need protection from frost in winter) Masses of bright blue, trumpet-shaped florets, each with darker stripes on the petals, form huge, rounded globes on top of the sturdy, upright stems. These create quite an impact above the evergreen foliage, and are excellent for adding structural interest to the border. Garden care: Apply a balanced liquid fertiliser monthly from spring until flowering. In cold areas, protect the crown of the plant with a deep, dry mulch to protect them from hard frosts, or grow in a pot so they can be overwintered in an unheated greenhouse. Divide plants in spring. Divide plants that have become too big in spring, but remember you will often get more flowers when the roots are constricted.
