Annual cosmos are extremely popular bedding plants and cutting flowers that bloom their socks off from May until Autumn, lasting for up to a week in a vase. They are easy to grow, ideal for containers, pretty much pest free, reaching 60-90cm tall.
We sell Cosmos seedlings in jumbo plugs. They arrive well-rooted, and ready for planting or potting.
Your seedlings must be unpacked, watered, and either plants or put in a sunny place as soon as they arrive. If planting will be delayed, water them every 48 hours, but do try to plant them ASAP.
Please note that annual plants are not covered by our guarantee, because they are not supposed to last that long!
