Colorado Mix Yarrow is a frost-hardy perennial that brings an irresistible riot of color to any sunny garden. This heirloom Achillea millefolium cultivar produces dense clusters of tiny daisy-like flowers in blood red, cerise, cream, yellow, and white, blooming reliably from summer through fall and persisting even as cold weather arrives. Reaching 24 to 30 inches tall and wide, it thrives in Zones 3 and above, tolerates drought with ease, and needs no fussing once established.

Each flower head is actually composed of scores of tiny florets packed tightly together, creating a visual texture that rewards close observation. The color range is genuinely striking: blood red, cerise, cream, yellow, and white all perform in a single planting, giving you a natural cottage garden palette without any extra work. These flowers last an impressively long time both on the plant and in a vase, and they keep blooming well into late fall when most other summer flowers have faded.
Colorado Mix Yarrow is grown primarily as a cut flower and ornamental for borders and cottage gardens, where its long bloom season and extended vase life make it particularly valuable. As an edible variety, the flowers and foliage can be harvested and dried for herbal tea, and the plant has traditional medicinal applications. Its strong appeal to pollinators also makes it a strategic choice for gardeners supporting bees and other beneficial insects.

Start seeds indoors 8 to 10 weeks before your last frost date. Sow seeds on the surface and press them in lightly, then cover with a light dusting of vermiculite. Keep the seed tray at about 70°F until germination occurs (expect sprouting in 10 to 14 days), then lower the temperature to 60 to 65°F. This temperature reduction after germination strengthens seedlings and encourages compact growth.
Transplant seedlings outdoors after your last spring frost, spacing them 24 inches apart. Harden off plants gradually over several days before planting out to acclimate them to outdoor conditions.
Direct sow seeds at your last frost date through early summer. Sow on the soil surface and press seeds in lightly; they need light to germinate.
Cut flower clusters once they have fully opened for fresh arrangements or drying. For herbal use, harvest foliage and flowers during the growing season by cutting stems cleanly above a lower leaf node. Harvest continues through late fall; the plant reliably produces flowers until very cold weather arrives. Cut flowers last a long time in a vase when harvested at peak bloom.
