Product Description

About Bright Lights Mixed Cosmos: Because of their Mexican heritage, these bright annuals meet high heat and drought conditions with native beauty and vigor. Spanish conquistadors searching for gold discovered these flowers on their journeys through Mexico. Mission gardens often included these flowers, which priests gave the name “cosmos,” the Greek word for a harmonious whole, because of their neatly spaced petals. Cosmos flowers made their way to England with Spanish ambassadors in the late 18th century, and to the United States in the following century.

Bright Lights Mixed Cosmos Germination: In early spring or after the last frost, scatter the seeds on the surface of loose soil. Keep the soil lightly moist until germination, which should take place within 10-20 days at soil temperatures from 65-75 degrees F. Cooler soil temperatures may delay germination. Seedlings do not need to be thinned, but can be transplanted if they appear too crowded. Since these seeds germinate quickly in warm soil, they can be sown at any time before midsummer for another crop of flowers. To start the seed indoors, sow on the surface of a flat 6-8 weeks before the last frost of spring; keep the soil evenly moist and at a temperature of 70-75 degrees F until germination. Keep the soil fairly dry after the seedlings appear; when there is no chance of frost, transplant them outdoors. The soil does not need to be rich, but it must be well-drained; light shade is tolerated, but will dramatically lessen the amount of blooms.

Growing Bright Lights Mixed Cosmos Seeds: As soon as seedlings appear, only water them in very dry weather. This flower must not be over-watered, and thrives in drought conditions and heat; if prolonged drought occurs, give the plants one deep watering. If blooming begins to decrease, cut the plant back to 12” for new growth; more blossoms will come in about 4 weeks. If allowed to self-seed, this flower will produce a new crop of flowers next year. This flower attracts birds, butterflies, and bees.

Harvesting Bright Lights Mixed Cosmos: Cosmos blossoms make lovely, long lasting cut flowers. Cut long stems of blossoms that have just opened, and remove any foliage that will fall below the water level. These flowers usually have a vase life of 7-10 days. Cosmos blossoms also make attractive dried flowers.

Saving Bright Lights Mixed Cosmos Seeds: Allow the flowers to drop their petals and develop into spiky seed heads. When ripe, the heads will be brown or dark brown and easily broken apart to reveal the narrow, sharp seeds. Remove the ripe seed heads and spread them out to dry away from direct sunlight. When they have completely dried, break apart the heads to separate the seeds from the husk. Store the cleaned seed in a cool, dry place.

Cosmos sulphureus (Cosmos 'Bright Lights Mix') Wildflower Seeds
Pretty, and TOUGH!
By 
I have nothing but good to say about 'Bright Lights'. I've grown them for several years, and they are *tough*! Mine have their own bed in a sunny spot in my yard, and in spring, I remove any debris, then run over the soil with a garden weasel to loosen it a little, throw some seeds down, and walk away. The soil is only so-so; it's been my experience that if the soil is too rich, they'll be 8' tall and have lots of leaves, but fewer flowers, and they'll need staking. Mine have survived up to six weeks without any rain, in full sun and temperatures up to 100 degrees, and the worst they do is drop some lower leaves. Bees love them, butterflies love them, even hummingbirds will visit them, and the seeds are very easy to collect. They'll happily self-seed, too. I once had a few seeds drop into a houseplant I had outside for the summer, and they not only germinated, but produced small blooms...indoors...in winter. Bright Lights will *always* have a place in my butterfly garden!
