250 Cosmos Sulphur Klondike Bright Lights Flower Seeds
The Sulphur Cosmos does well in hot, arid climates. It is native to Central America and can grow in temperatures up to and above 100 degrees Fahrenheit. This flower will bloom later in the season than many others. When located in parched climate areas it can be planted in the fall. In colder, more moist climates wait to plant this seed until spring when the ground warms up. Otherwise the seed will sit dormant in the ground and rot, because heat is a necessary precursor to germination for this species.

Sowing: 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. When there is no chance of frost, transplant them outdoors.
Growing: Water these plants regularly until they begin to bloom; at this point they become quite drought tolerant. This flower must not be over-watered, and grows well in drought conditions and heat; if prolonged drought occurs, give the plants occasional deep watering. 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.If blooming begins to decrease, cut the plant back to 12" for new growth; more blossoms will come in about 4 weeks. Tall plants may need support or staking. If allowed to self-seed, this flower will produce a new crop of flowers next year. This flower attracts birds, butterflies, and bees.
All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.
