(Cosmos bipinnatus) Cosmos is an annual member of the asteraceae, or daisy, family. Plants will readily reseed in place the following spring. They grow easily from seed and tolerate a wide range of soil conditions, thriving in poor soil. Cosmos are quite drought and heat tolerant but do not handle frost. These carefree flowers are a staple for landscaping and cut flower production. Plants prefer full sun and poor or moderate soil. (Excessively rich soil leads to lots of foliage but few blooms.) Seeds germinate in 7-14 days. Direct sow outdoors after all chance of frost has passed and soil has reliably warmed to 60 F, or start indoors 3-4 weeks before the last frost date and transplant out after frost has passed. Ideal germination temperature is 86-75F. Space cosmos 9-12 inches apart, taking into account the variety as they will range in height and width.
We love these incredible rose-like flowers on this stunning cosmos variety from Holland. The ballerina pink, semi and fully double blooms are a cheerful addition to the cottage garden, floral designs and the landscape. It’s no wonder this variety is a favorite for cutting; the blooms are sturdy and stunning with long stems. Plants average 4 feet tall. A real standout in our trial gardens this last year, and a new favorite!
The most alluring and eye-catching cosmos, with pale pink petals and dazzling magenta picotee. The flowers have a smaller row of second petals, making them a semi-double. This 3.5-foot-tall variety is perfect for cutting, landscaping or container growing. Lovely choice for floral design and cut flower sales. We love these!
A subtle yet striking cosmos from Japan. The elegant petals are the lightest pastel shades of yellow, cream, rose and peach. The 4-foot tall plants make soft clouds of soothing color, perfect for the back of the border and lovely in arrangements. A totally unique and different color in cosmos that is beloved by gardeners and pollinators alike!
