Thompson & Morgan - Flower - Cosmos - Sensation Mixed - 200 Seed
Cosmos - Sensation Mixed
Imposing tall ferny foliage graced by large colourful blooms all summer through to the autumn frosts. A superb annual for adding some height to your bedding displays, or dotted into a mixed border. Height: 120cm (47”). Spread: 60cm (24”).
Start off in a seed tray indoors and plant out in borders. Fill a seed tray with good, free-draining, damp, seed compost. Sow seed on the surface of the compost and cover with a very fine sprinkling of dry vermiculite or finely sieved compost. Place the seed and tray in a propagator or seal inside a polythene bag and keep at around 20-25C (68-77F) until the seeds germinate. This will take about 7-14 days. Don’t exclude light as this helps germination.
When the seedlings are large enough to handle, transplant them individually into 7.5cm (3") pots or multi-cell trays. Before planting out, acclimatise the plants to cooler conditions by putting them outside for a few hours a day for a few weeks. Plant out when all risk of frost has gone about 45cm (18") apart.
