Brightly hued flower clusters and attractive foliage.
Its large, bright golden flowers bloom during summer in flat, plate-like compound corymbs about 4" across. These flower clusters grow atop tall stems that rise above foliage consisting of finely cut, aromatic leaves that are grey-green in color and produce visual interest for much of the year. Butterflies can't resist the blooms, which make excellently dried or fresh-cut flowers.

How to Plant Colorado Yarrow:
WHEN TO PLANT YARROW SEEDS
Start Yarrow indoors 6-8 weeks before the last frost of the season, or sow directly into the garden after the last frost of the season has passed.
WHERE TO PLANT YARROW SEEDS
Yarrow thrives in well-draining, dry, sandy loams with access to full sun (6-8 hours of sun per day) and protection from high winds. Avoid rich, moist soils, or the plant tends to suffer and flop over or become leggy. Yarrow plants will readily spread via seeds or rhizomes, so it may be beneficial to plant in an area with plenty of room for Yarrow to populate.
HOW TO PLANT YARROW SEEDS
When started outdoors, spread Yarrow seeds via broadcasting into moistened soil and do not bury or cover them, as light is required for the germination process. Keep the soil moist as the seeds germinate. Weed out weaker plants until plants are 18-24 inches apart as they grow larger or as they are transplanted into the garden from indoors.
HOW TO CARE FOR YARROW
Deadheading of spent flowers encourages a new flush of bloom throughout the season. Water Yarrow sparingly but deeply. On particularly hot days, a bit of water may revivify the plant. Yarrow will aggressively spread through reseeding or via rhizomes, dividing the plants every few years can facilitate the health of the plant. After the blooming season ends, the plant can be cut back to the ground to tidy up the planting area.
