I am waiting for the young plants to gain a bit of strength in their pots before planting them out in their final positions.

Graden Merit Value-for-money
A shade-loving perennial remarkable for its large, heart-shaped leaves that are almost entirely silver and remain decorative until autumn. In spring, clouds of small light-blue flowers resembling forget-me-nots rise above the carpet of leaves. Very hardy and undemanding, this brunnera prefers partial shade and a humus-bearing soil that remains moist. Excellent groundcover under deciduous shrubs.

Planting and care

Brunnera macrophylla ‘Jack Frost’ is preferably planted from March to May or from September to November, in partial shade or light shade. Plant it in humus-rich, moist, well-drained soil. In poor soil, incorporate well-rotted compost or leaf mould; in heavy clay, work the soil thoroughly so that water does not stagnate. Lime is not a problem. Water regularly during the first season, especially under trees where root competition can quickly dry out the soil. A well-established plant tolerates short drier spells in shade, but watering during hot spells is beneficial. An organic mulch helps retain moisture. Leaves that are scorched or badly damaged in summer can be cut back: new leaves will form again if the soil remains moist. Division is carried out in early spring.
