Cosmos bipinnatus. Yes, it’s a Cosmos! Rose Bon Bon cosmos seeds are a new Fleuroselect Award winning variety from France, and part of the Double Click Cosmos series. Fully double flowers appear in soft rose pink on easy-to-grow, medium sized plants. Height to 1.2m (4′). This exquisite annual makes a wonderful cut flower, with petals almost as curled as Dianthus. Rose Bonbon really stood out for us at the All American Selections flower trials this past summer in Ontario. Major “Wow” factor!

Cosmos will flower more in poor soil, rather than rich, so avoid manures and fertilizers. Pinch out the growing point when plants are around 45cm (18″) tall to encourage bushier growth and more flowering points. Water during very dry spells, but otherwise, Cosmos is well suited to xeriscaping. Seeds are easy to harvest and save.
These annual plants that are sometimes referred to as Cosmea.

Cosmos bipinnatus & C. sulfureus
Family: Asteraceae

Direct sow from early March right up until mid-June. Several sowings will result in a very long bloom period. You can also start Cosmos indoors in February to early March for transplanting late March to mid-April. Seeds will sprout in 3-10 days. Optimal temperature for germination: 21-25°C (70-75°F).

Sow seeds very shallowly only a few millimeters (1/8″) deep. Thin or transplant to 20-25cm (8-10″) apart.

    (verified owner):

    Not only easy to grow but forgiving as well. I transplanted way later than I should have (August) in a 10″ container and still managed to flower in late October. I think they were smaller blooms, so not full potential but still! They survived this newbie haphazard gardener! I’m excited to grow for them for next year!
