Salvia ‘Blue Marvel’: is a lovely plant as a border along a path with multiple stems creating a clump of bright blue flowers with bees buzzing all summer . This is a winning sight when mass planted. Plant in a sunny position in good friable soil that is well drained.
The shorter stems at the side, give the appearance of many spires of blue flowers.
Grow S. ‘Blue Marvel’ with other small pink, crimson, white and even yellow groundcovers and perennials. Grow in the front of other taller perennials or in front of small hedges.
At the end of autumn as the plant is preparing to become winter dormant, cut flower stems down by half (use these as an marker), clean out old leaves, mulch well to keep the crown warm over the cold winter months. Feed in spring when the new shoots begin to show.
Propagation: Cuttings can be taken in the spring from new growth, but this Salvia is mainly grown from seed or by dividing clumps in Autumn.
