This popular, pure white annual cosmos makes a great filler plant for a sunny, moist but well-drained border. Dead-head 'Purity' regularly and you'll have 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.
Our seedlings are grown individually in cell trays, and each plant measures about 4 - 6cm tall (from the base of the root to the top of the plant).
Our jumbo seedlings are grown individually in cell trays, and each plant measures about 7 - 10cm tall (from the base of the root to the top of the plant). They are delivered in plastic-free packaging.
These seedlings 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: As we grow the seedlings especially for you, we do request that full payment is made when you place your order. See above for despatch dates. To ensure that your plants arrive in the best possible condition each pack will be despatched individually.

Garden care:
Seedlings should be potted up and grow on under glass until all risk of frost has passed and they can be planted outside in a well-prepared bed. Pinch out the growing tips to encourage bushier growth, and feed at regular intervals throughout summer with a high-potash fertiliser. Taller plants may need supporting with brushwood stems in exposed positions.
In early spring, sow seed 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 in mid- to late spring in a well-prepared bed and thin the seedlings out as they grow to allow approximately 30cm between each.
