Buy Cosmos bipinnatus 'Purity' 40 plus 20 FREE large plug plants: 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, pure white annual cosmos makes a great filler plant for a sunny, moist but well-drained border. As long as it's dead-headed regularly it will produce a succession of graceful, pure white, saucer-shaped flowers up to 10cm (4in) in diameter from June to October and masses of feathery, mid-green leaves.

    Grown in individual plug cells, each plant measures about 5 - 7cm tall (from the base of the root to the top of the plant). They are ideal for keen gardeners who have a greenhouse where the plants can be grown on until they are ready for planting out in the garden once all chance of frost has passed.

    Please note that as we grow these for especially for you, we need to take full payment when you place your order so as to reserve stock for you. See above for despatch dates for this particular plant. To ensure that your plants arrive in the best possible condition each pack will be despatched individually.

Exeeded expectations


We have had a new small bed created at the front of the house which I planted with perennials , shrubs and roses. As all the plants were quite small I filled the space with Cosmos Purity, they have taken over (due to my inexperience, I didnt realise they woul be so big) but they are so easy to grow (deadhead reguarly) and really pretty. They have been flowering for weeks now and are absolutely covered in buds. I'm really pleased with the plants, they were tiny when they arrived but grew on quickly. I love them so do my neighbours and the bees do too. Definitely getting these again.






Lovely and healthy and bee friendly. It would be good to have the option of a half a pack (20+10) of the same size or larger plugs or even young plants that can go straight into the garden. I understand that the extras are to cover for the loss of some of the plugs but even then I ended up with far too many. Or a possibility of the bedding plants combination of two or four different types of plants.




Back to perfection


After a disastrous experience the previous year caused by poor packaging I was hesitant to re-order but I didn't need to worry. Improved packaging meant that the seedlings arrived in perfect condition and after a few weeks strengthening in pots they planted out well and lasted all season providing constant flowering as more seasonal plants died back. Regular deadheading and an occasional feed kept the plants going.




I would buy these plants as plugs again


Great plants and stunning flowers going into November, showy and very easy to nurture


Wiltshire/Dorset border




Managed to get only 4 plants from 18 plugs to plant out.




Great border filler


Very pretty annuals that flowered and flowered until the first frosts. Excellent for those spaces in the border. Tall but delicate.

Would this variety need staking, seeing as it grows up to 1.2 m?


Hello, Yes, these may need supporting with brushwood stems - particularly if grown in exposed positions.

If you do nothing else...water new plants. Make sure new additions do not suffer during dry spells. Plant up summer containers bedding once the threat of frosts has passed. Feed container plants about six weeks after planting. If it’s a nice day...trim he

Plant up summer containers

After the last frost date, plant up containers with tender flowering bedding and reliable foliage plants. Line terracotta pots with polythene, taking care not to cover the planting holes, to reduce water loss through the porous sides of the pot.

Posh bedding

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
