Fluted velvet crimson red petals with the usual yellow cosmos centre. The fern like foliage makes this plant an amazing 'back of border' feature and ideal for cutting too. Cosmos grows to about 1 metre tall. Produces lovely flowers throughout the summer.
Sow the seeds about 0.5 cm deep in March-April inside in small pots or tray in fine compost. Can also be sown directly outside in May into well prepared, finely raked soil.
Transplant seedlings into bigger pots when large enough to handle and grow them on in cooler conditions. Acclimatise to outdoor conditions and plant out into final position after all risk of frost has passed. Prefers full sun and well drained soil. The growing tip can be pinched out to encourage sideshoot production, making the plants more bushy.
