Description

A beauty like no other, the Candy Stripe variety has a golden center flanked by white petals with rosy edges and striping, making one sweet cut flower! Once established, cosmos are drought tolerant; neglect is the kind of care they prefer. They reseed readily, making them ideal for wildflower or naturalized areas.

They attract pollinators like bees and hummingbirds!

Planting

Cosmos seeds are super easy to grow! The seed can be fall planted, started indoors in the early spring, or directly sown outdoors after the last chance of frost has past. The seeds need to be lightly covered, about one-sixteenth inch (or raked if outdoors in the ground). Make sure not to bury them too deeply in the soil, or they may not grow.

Keep the seeds moist and germination will occur quickly. The best soil temperature for germination is around 70–80°F. Space (or thin) the plants about 9–12 inches apart.

It is recommended to start cosmos directly in the garden.

Seed Saving

Cosmos seed saving is simple! Wait for flowers to dry completely on the plant, then snip off dried flower heads and place into a paper bag. Once you have brought them inside, you need to remove the seeds from the seed head. This can be done by hand. You will have to remove any chaff from the seeds, as this may cause the seeds to go moldy when they are stored.

Only keep the largest and fattest seeds. Any seeds that feel soft when you gently squeeze them between your fingers should be discarded. Allow the seeds to fully dry and store in a cool, dry place for up to two years.
