The cosmos never looked quite so sunny as with Cosmos sulphureus ‘Bright Lights.’ This annual is an easy flower to grow and can be direct seeded in the spring, preferring full sun and moderately fertile soil. In Maine, this Central American native grows between 1 and 3 feet in height, although it has been known to reach 6 feet (perhaps where the growing season is a bit longer). In shades of yellow, orange and red, ‘Bright Lights’ sports daisylike flowers atop airy foliage that is not as finely cut as that of its relative Cosmos bipinnatus. As true with other cosmos varieties, deadheading can help prolong the flowering period. It readily self-seeds and in some areas of the country has been declared invasive because of this tendency.
