Product Description

Sulphur Cosmos Seeds "Orange"

This is the classic "sulphur" or simply, "orange" cosmos that is often cited as one of the most stunning of all the meadow wildflowers. An extremely vigorous, resilient, and colorful flower, it is a favorite of both home gardeners and US state Department of Transportation, which plant it in abundance along the highways and bi-ways of the country because of its ability to dazzle. A mid to late season bloomer, it is best appreciated when planted in abundance.

    How to Plant & Grow Cosmos Flowers from Seeds

    This Mexico native is one of the simplest flowers to grow, and they are suitable for all zones. Since they reseed themselves easily, they make perfect additions to wildflower meadows or naturalized areas. Children will love planting their cosmos seeds and watching them grow taller than they are!

    Sow your Cosmos seeds in the full sun to partial shade. As cosmos flowers are very adaptable, they can thrive in average to poor soil quality, and they are tolerant to dry conditions. Scatter cosmos seeds outdoors after there is no longer a danger for frost. Seeds can be covered ¼ inch since they do not need light to germinate. Germination will usually occur in just 3 to 5 days, but it can take up to 2 weeks.

    Once started, cosmoses require virtually no attention. You can add a general purpose fertilizer once or twice a season. If a plant grows very tall and is not planted in a wind protected area, it may require staking. If you want blooms all summer long, dead head the old blooms.
