Lobelia - Cambridge Blue
Cambridge bleu has a lovely compact habit produces a neat bush-like plant of bright green leaves topped with masses of tiny pale blue flowers.
Sow from January to March on the surface of slightly firmed, moist seed compost in pots or trays. Do not cover the seed. Place in a propagator or a warm place and keep at a temperature of between 20-25°C. After sowing do not exclude light as this helps germination which usually takes 10-21 days. When seedlings are large enough to handle transplant into pots or trays. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost has passed, 23-30cm apart or plant into baskets and containers filled with a good quality potting compost. Flowers from May onwards.
