Cosmos bipinnatus Ex. Semi-Double White

| Cosmos, semi-double white | ||||||||||||

||||||||||||
| Masses of pure white, semi-double blooms with yellow centres (with perhaps the odd single) throughout the summer, on tall stems with finely divided foliage. Drought tolerant. Some say it is unnecessary to thin direct sown plants. Soil that is too rich may result in tall, lanky plants. I cannot guarantee that all seeds will come true, but these seeds were gathered from plants that were grown in the white-planted area of the garden, so cross-pollination should be at a minimum. | ||||||||||||
| Sowing and/or growing instructions | ||||||||||||
| Can be sown direct, lightly raked into the soil, thinning to approx. 18in apart. Alternatively, sow under cover in spring in modules or seed trays, at 68-77F/20-25C. Do not exclude light, which aids germination. Move into individual pots as the plants develop. Wait until frost no longer poses a threat before planting into open ground. Pinch out growing tips once the plants are about 9-12in tall, to encourage branching. Prefers a fertile, moist soil in full sun. Discard any seedlings that have red stems as they will tend to produce pink flowers - or grow them on to plant elsewhere. |
