Yarrow is a popular perennial plant known for its feathery foliage and clusters of colorful flowers. It is widely used in gardens for its hardiness and ability to attract pollinators. When expanding your garden or renewing your yarrow plants, division is an effective propagation method. However, selecting the right yarrow variety for division ensures healthy growth and vibrant blooms.
Common Yarrow Varieties
Yarrow (Achillea millefolium) comes in a variety of cultivars, each with unique characteristics. Understanding these differences helps in choosing the best type for your garden.
Achillea millefolium ‘Paprika’
This variety features vibrant, orange-red flower heads and aromatic foliage. It is drought-tolerant and thrives in full sun. ‘Paprika’ is ideal for division if you want to add a splash of color to your garden beds.
Achillea ‘Moonshine’
‘Moonshine’ is known for its silvery foliage and bright yellow flowers. It is a hardy and low-maintenance variety, making it perfect for division and creating a cohesive garden look.
Achillea millefolium ‘Red Velvet’
This cultivar produces deep red flower clusters and dark green foliage. It prefers well-drained soil and full sun. Dividing ‘Red Velvet’ helps maintain its vigorous growth and vibrant color.
Choosing the Right Yarrow for Division
When selecting a yarrow variety for division, consider your garden’s climate, soil type, and aesthetic preferences. Some varieties are more tolerant of moisture, while others excel in dry, sunny locations.
Factors to Consider
- Climate suitability: Ensure the variety is hardy in your USDA zone.
- Sun exposure: Most yarrows prefer full sun for optimal flowering.
- Soil type: Well-drained soil is essential to prevent root rot.
- Color and appearance: Choose a variety that complements your garden design.
Timing for Division
The best time to divide yarrow is in early spring or late fall when the plant is dormant. This minimizes stress and promotes healthy root development. Use a sharp spade or garden fork to carefully separate the clumps.
Steps for Dividing Yarrow
Follow these steps to successfully divide yarrow:
- Water the plant thoroughly a day before dividing.
- Dig around the base of the plant to loosen the root ball.
- Use a clean, sharp spade or knife to divide the clump into sections, each with roots and foliage.
- Replant the divisions at the same depth they were growing before.
- Water well and mulch to retain moisture.
Proper division encourages vigorous growth and maintains the health of your yarrow plants, ensuring they flourish for years to come.
