Cosmos (Cosmos Bipinnatus Mix) - One of the most popular annuals to grow from flower seeds, Cosmos Bipinnatus, provide such an amazing display of color for the little amount of work they require. This seed mix has colors of pink, white, and maroon. What a fabulous sight to see this mix of colors in a field or meadow! They naturalize very easily and are attractive to bees and butterflies. Sometimes the name Mexican Aster is used for these flowers.
Cosmos Bipinnatus seeds look like miniature pine needles, so they are easy to work with and sow. They don't mind over crowding, so scattering the flower seeds over freshly tilled bare soil is a fast and easy seeding method. After scattering the seeds, compress the them into the dirt and cover lightly with no more than 1/16 inch of soil. Keep the soil moist, and very shortly fast-growing, fern-leaved plants will shoot up. When the seedlings are 4 - 12 inches tall, they transplant very well. Dig them up and move them wherever you would like them to grow.
When Cosmos Mexican Aster flower seed is planted in the early spring, it is not uncommon to have a second planting in summer. By mid-summer there may be an abundance of dried seed pods. You can encourage re-bloom simply by cutting the plants back to 12 - 18 inches high. Allow those seed pods to open and drop their flower seeds onto the soil. Cosmos plants are liberal self-sowers, so helping them along just means there will be more blooms!
