Cosmos - Brightness Mixed
This is possibly the most free-flowering Cosmos mix. The dwarf and bushy plants are covered with flowers in a delightful mixture of gold, lemon, orange and red from early summer through to the autumn frosts. It looks spectacular when planted towards the front of annual borders or in containers.
Sow March to May on the surface of a good, free-draining, damp, seed compost. Cover 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 7-14 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, 3cm apart.
