Cosmos Sulphur Orange Seeds - Cosmos Sulphureus
Cosmos Sulphur Orange Cosmos Sulphureus is a half-hardy annual wildflower native to American Southwest and Mexico. It is very easy to germinate Cosmos Sulphur Orange seeds, and also called Klondike Cosmos, this tall, bushy and well branched annual flower produces double and semi-double, bright orange flowers on a top of deep-green, finely-cut, airy foliage. Orange Sulphur Cosmos starts to bloom prolifically in late spring or early summer and blooms nonstop until first frost. The fragrant, showy Cosmos flowers attract bees, butterflies and hummingbirds.
Cosmos Sulphur Orange is an outstanding wildflower for mass planting in meadows, along roadsides, walkways and just everywhere else in a garden. Cosmos is a popular, long-lasting cut flower, so the cutting gardens benefit tremendously from the presence of Cosmos flower. It is recommended to keep Cosmos Sulphureus seeds moist until germination, and once the seeds are germinated, Sulphur Cosmos establishes itself rapidly, and the mature Cosmos is disease free, heat and pest-resistant, drought and heat tolerant annual plant that can thrive even in poor, dry soils. Klondike Cosmos re-seeds itself easily.
