HOW TO GROW

Sowing: In early spring or after the last frost, scatter the Bright Lights Sulphur Cosmos 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 Bright Lights Sulphur Cosmos 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. When there is no chance of frost, transplant them outdoors.

Growing: 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: 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.

Seed Saving: Allow the Bright Lights Cosmos 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 Bright Lights Sulphur Cosmos seed in a cool, dry place.

Great for the lazy gardener

True "throw-n-grow" seeds! The best kind of gardening. You do have to give them a chance against other weeds, so it's best to prepare the area, but even if you don't, you'll still get one or two to survive. If you want a bunch of flowers, then smothering weeds with newspapers, sprinkling the seeds, adding a handful of soil to barely cover the seeds and hold down the newspapers, and wetting it all down should be enough to impress the butterflies and neighbors. Watering is the key. Too dry = scraggly, miserable flowers, too wet = more greenery than flowers, just right = multiple blooms, almost more than leaves.

Great plants

Packaging is superior. In south Florida, these plants self-sow without being rambunctious, like the heat, and require little watering.

Ridiculously easy, glowing colors.

Such a vibrant flower! I am seeing two distinct types of growth, under exactly the same conditions. I have finely cut foliage and relatively early bloom on most, with mid height plants. Then I have a few lush, thick leaved, tall, juicy specimens of plants that are much later to bloom (like, it's late August and no buds yet). Maybe the soil in those few areas is too rich? I dunno. They still look nice, but not a flower in sight.

Zinnia and Cosmos flower Seeds

I bought 1 pound each of 2 Zinnia types and a Cosmos mix. Came in 3 days. I have purchashed j-1/2 pound packs in the past. Nice sealed bags that reseal easily will keep this seed for 3 or 4 years. I always get high germination and many years of pleasure from these larger bags. Seeds are germination tested. Store bought seeds in small paper packs never germinate as well. And, forget about them still being good into the future.

Pretty, and TOUGH!

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!

DESCRIPTION

IN-STOCK ORDERS SHIP WITHIN THE NEXT BUSINESS DAY. Light up the landscape with these cheerful red, orange, and yellow blossoms that are shorter than most Cosmos varieties. This easy-to-grow annual will reward the gardener who does not have much time to fuss with plants.
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.
