Aster - Starlight Mixed
This is one of the best dwarf Asters! Intriguing spider-like flowers smother compact basal branched plants in attractive shades of blue, purple, scarlet and rose. It is early to flower, adding a colourful display to borders or patio containers over a long flowering period. Height: 20cm.
Sow February to April. Sow seed on the surface of a good, free-draining, damp, seed compost Cover the seed with a very fine sprinkling of compost or vermiculite. Place in a propagator or seal container inside a polythene bag and place at a temperature of 20-25C until after germination which usually takes 7-21 days. Do not exclude light, as this helps germination. Transplant seedlings when large enough to handle into trays or 7.5cm pots. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost, 15-2cm apart.
