200 Sulphur Bright Lights Cosmos 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.
