Growing Achillea plants is easy. Also called Yarrow, they are among the hardiest of perennials. Originating in Asia and Europe, perennial Achillea is a common wildflower, that has become very popular in home gardens. The small flowers are grown on strong stems, so they make fine cut flowers for vases and bouquets.
With a prominent bloom from summer to frost, they make a great addition to your home flowerbed.

Achillea is grown from seed. Sow seeds directly seeded into your flower garden, or start indoors for transplanting later. For outdoor starts, plant Achillea seeds after the soil has begun to warm in the spring.
Sow seeds early in the season and cover lightly with soil.
Once your plants have been established, they can be propagated by separation in the fall.
Note: For indoor starts, we recommend using a heated germination mat, to increase the speed of germination. And, it, results in a higher germination rate.
Final Plant Spacing: Space plants 1 to 2 feet apart.
Days to Germination: Seeds sprout in 14 – 28 days.
Growing Achillea flowers is easy. They prefer full sun and well-drained soil. They will do well in average soils and tolerate dry soil conditions. Water Achillea plants during dry periods, once or twice per week. Add a general-purpose fertilizer once or twice a season.
In rich soil, Achillea will grow tall, 1-3 feet, and may require staking.
Once your Achillea is established, they will grow well and bloom until frost. Being very hardy, they will likely survive the first light frosts before going dormant for the winter. They do not require mulching or protection in the winter.
Ideal Soil pH: 6.0 – 8.0.
Plant Problems – Identify the causes and find the cures.
Perennial Achillea is resistant to insects and disease. If insect or disease problems occur, treat early with organic or chemical insect repellents and fungicide.
