Cosmos

(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.
