Cosmos sulphureus orange
Klondike Cosmos

Add summer fire to the garden with Cosmos sulphureus ‘Klondike’, a classic orange cosmos and Mexican aster with bright, sunny blooms that practically glow above lacy green foliage. This easy annual grows into a bushy, vigorous plant about 2' wide and 1' tall, with flowers held high on multi-branching stems up to 3' tall.

Also known as Klondike Cosmos or orange Mexican aster, this heat-loving flower is a wonderful choice for cottage gardens, pollinator plantings, cutting gardens, meadow-style borders, and sunny dry garden beds. The cheerful orange blooms attract butterflies, bees, and birds, while the airy foliage keeps the planting light and graceful. Plant it with zinnias, bachelor buttons, salvias, sunflowers, or ornamental grasses for a bold, easy summer display.

Plant Cosmos sulphureus ‘Klondike’ in full sun with well-drained soil. Once established, it is drought tolerant, forgiving of less-than-perfect soil, and blooms through autumn with deadheading. It may reseed where happy. Explore more bright, easy bloomers in our Cosmos - Mexican Aster collection.
