Salvia Superba “Merleau Blue” has very deep violet blue flowers which are borne profusely in mid summer into autumn. It is a good cut flower. It flowers in its first year from seed on a compact well branched plant. It is tolerant of drought when well established and is attractive to both butterflies and bees.
It can be divided in spring, and this should be done every 3 to 5 years to maintain vigour. It was a winner of the European Fleuroselect Gold Medal in 2007.
Sow indoors spring and early summer or approx. 8-10 weeks before last frosts are due. Sow onto moist well-drained seed compost. Cover with only a sprinkling of soil as light is needed for germination. Watch out for damping off. Ideal temp. 18-24°C. If temperature is not maintained germination can be erratic. Transplant seedlings when large enough to handle to 8cm pots. Increase pot size as the plant grows. Acclimatise and plant out after danger of frost has passed with 15-30cm spacing.
