Buy Cosmos bipinnatus 'Purity' cosmos: Graceful, pure white flowers


  • Position: full sun
  • Soil: moderately fertile, moist, well-drained soil
  • Rate of growth: average
  • Flowering period: June to October
  • Hardiness: half hardy annual

    This popular annual cosmos makes a great filler for a sunny border, and as long as it's dead-headed regularly, it will produce a succession pure white, saucer-shaped flowers from early summer to mid-autumn. It's very easy to grow and it makes an invaluable addition to the cutting garden.

  • Garden care: In early spring, sow shallowly in seed trays and keep under glass, transplanting them into individual pots when large enough to handle. Harden off before planting outside after the frosts. Alternatively, sow in-situ im mid- to late spring in a well-prepared bed and thin the seedlings out as they grow to allow approximately 30cm between each. As the seedlings grow, pinch out the tips to encourage bushier plants. Taller plants may need supporting with brushwood stems in exposed positions.

  • Sow: March-May

  • Flowering: June-October

  • Approximate quantity: 100 seeds.

Reliable with very attractive flowers. I have bought Cosmos Purity seeds year after year to climb up our willow arches and they have never failed to give us a stunning display. We also planted some under a redundant sweet pea frame in very different soil conditions and they did incredibly well there too. I always start our seeds in trays in the polytunnel, thin them out into individual polypots, harden them off in the cold frame and plant them in their final growing position when all chance of frost has passed.

Providing much needed late summer and autumn interest

Masses of pretty large white flowers over a long period, interesting folliage, quite tall plants, may need staking of some sort especially in high winds, make an impact late in the season, got compliments from visiting friends

Easy to grow from seed but as slugs like the young,plants I tend to grow them on in pots until strong. Once established they flower continuously. Pure white flowers and feathery foliage. They do need staking as the plants grow very large. I wouldn't be without them. They will flower almost to first frosts

Planted seeds in trays covered as directed. Placed inside the house and kept moist. Only 4 out of 15 are now seedlings and have been potted on successfully.

There is still plenty of time to raise hardier annuals from seeds sown now and these include cosmos, zinnias and marigolds. However it's often easier to opt for ready-grown plugs of these, as well as the more-tender begonias petunias, antirrhinums and ni
