More Details

There are few nicer ways of filling vases throughout summer and autumn than with a cloud of cosmos. As long as you don’t cut the plants right to the ground, but above a pair of leaves, more buds will form to fill next week’s vases and more for the week after that — and on and on it goes — your ever-filling vase.

This collection contains a mixed packet, or 5 or 10 seedlings of:
Genus Cosmos
Group/Species bipinnatus
Variety Candy Stripe, Purity, Seashells Mixed, Xsenia
Type Half-Hardy Annual
Common Name Mexican Aster
Border Position Cutting Garden
Soil Type Broad Tolerance
Site Full Sun
Moisture Moist but Well-drained
Height 90cm (36in)
Spacing 45cm (18in)
Sowing, Seeds, Planting Sow direct early May or under cover, approximately six weeks before the last frosts in your area. Grow seedlings on until large enough to plant out. Gradually acclimatise to outdoor conditions, or 'harden off' young plants for 7-10 days before transplanting into the garden after all risk of frost has passed.
Care Tips Pinch out tips at 15-20cm to encourage bushier plants. Stake and tie plants if necessary as they grow. Water regularly and dead-head to encourage more blooms.
Flowering July - October, 12-14 weeks from sowing.
Vase Life Last 7-10 days, no conditioning needed. Pick fresh straight into water, just as the buds are about to bloom, and do not pick in the heat of the day. Deadhead the main blooms that are drooping and going over after about a week. Place out of direct sunlight.
