Salvia ‘Blue hills’ superba: is a low clumping herbaceous Salvia, growing to 20 cm H with spikes of sky blue flowers in late spring and summer.
Salvia ‘Blue hills’ is often known as Salvia ‘Blauhugel’
Flowers: are small and pale sky blue, appearing all along the flowering stem in small whorls of 2-4 flowers in spring and summer. This is a falcate type of flower where the bottom lobe is paler than the hood. These lobes are cupped to act as a landing point for bees and other pollinating insect. They find these flowers very attractive. In mid to late summer, these flowers can be seen buzzing with bees .
Calyces: Are green, ribbed with small clear hairs along the ribs. The bracts often stay after the flower has opened.
Leaves : are small, grass green, lineal with a short pointed apex, often having a slight wavy appearance. These form a rosette basal type of growth, forming a clump before sending up the flowering stems. Some sessile leaves appear further along the flowering stem.
Salvia ‘Blue hills’ is a dainty looking clumping Salvia that is ideal for a border. Grown a number plants together , they make a wonderful display.
Grow with other small perennials and groundcovers. They look good with other pale pink and white Salvias and perennials.
Best grown in a sunny position or a sunny protected position from hot winds during summer. Although very hardy for the hot dry summer conditions when established, they grow better if well mulched to keep the root area cool.
As S. ‘Blue Hills‘ is winter dormant, this mulch over the crown will protect against frost and slugs when the leaves appear in spring.
Propagation: Tip cuttings can be taken in spring before the flowering stems appear or divide the clump in early spring, again before flowering begins. Often grown from seed.
