A compact variety renowned for its excellent garden performance. Clear sky-blue lobelia flowers are set above narrow, airy foliage on compact plants. Lobelia 'Cambridge Blue' makes a sparkling addition to beds, containers, flower Pouches® and window-boxes, and even looks well placed in the rockery. An easy to grow annual that is deservedly popular for its versatility and long flowering period. Height: 10cm (4"). Spread: 15cm (6").
Sow lobelia from late winter to mid spring on the surface of a good seed compost and gently firm down. Place the seed tray in a propagator at a temperature of 18-24C (65-75F) or seal it inside a polythene bag. Keep the soil damp but not wet. Do not exclude light as this aids germination which usually takes 14-21 days.
When seedlings are large enough to handle, transplant and grow them on in cooler conditions until large enough to plant outdoors. When lobelia plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over 7 to 10 days. Transplant outdoors in full sun or semi-shade on moist, fertile, well drained soil at a distance of 10cm (4") apart.
