Description How to Grow More Info Delivery
A modern alternative to marigolds, these dwarf and bushy plants will quickly fill beds, borders and containers with carpets of fiery colour. Semi-double blooms in clear shades of red, yellow and orange are borne on short sturdy stems, above mounds of feathery green foliage. Spectacular when planted towards the front of beds and borders, Cosmos sulphureus 'Brightness Mixed' flowers continuously from summer through to autumn and the blooms are highly attractive to bees and butterflies. Height and spread: 30cm (12").

Culinary note: The blooms will add zest to your meal by adding bright splashes of colour, while the young leaves can be added to salads or eaten straight. For more details about edible flowers click here.

Pot up cosmos plants and grow them on in warm, frost free conditions until large enough to plant outdoors. When all risk of frost has passed, gradually acclimatise cosmos plants to outdoor conditions over 7 to 10 days before planting out in beds, borders and containers. Choose a position in full sun on any moist, well drained soil.
