Compact yarrow is a dense, low-growing cultivar of common yarrow, typically reaching 12-18 inches tall with feathery, finely divided foliage and flat-topped flower clusters in vibrant colors. It's a hardy perennial that blooms prolifically from early summer through fall and attracts pollinators while requiring minimal maintenance.

Growing Conditions

☀️
Sun: Full sun, 6-8 hours daily minimum; tolerates part sun but flowers best in full sun

📏
Spacing: 12 inches
📅
Days to maturity: Blooms first year if started from transplants; 60-90 days from seed to first flowers
🌱
Planting depth: Surface sow seeds or barely press into soil; do not cover as seeds need light to germinate. Plant transplants at same depth they were growing.

Soil

Type: Well-draining, sandy or gravelly soil; tolerates poor soil
pH: 5.5-7.5
Amendments:
Perlite or coarse sand for drainage Avoid rich compost or excessive organic matter

Growth Stages

1

Seed & Germination

1-2 weeks

Tiny seeds require light and warm temperatures (60-75°F) to germinate.

Surface sow on moist seed-starting mix. Keep soil lightly moist, not waterlogged. Germination occurs in 7-14 days. Provide grow lights or bright windowsill.

2

Seedling

3-4 weeks

Small plants with fine, thread-like emerging foliage develop true leaves with the characteristic feathery texture.

Thin seedlings to 6-8 inches apart. Keep soil moist but not soggy. Once true leaves develop, gradually reduce watering. No fertilizer needed.

3

Vegetative Growth

4-6 weeks (or until transplanting outdoors)

Plant develops a compact mound of dense, finely divided silvery-green foliage; no flowers yet.

Transplant to 3-4 inch pots when 2-3 inches tall. Harden off gradually before planting outdoors. Space 12 inches apart. Minimal watering; allow drying between waterings.

4

Flowering & Blooming

June-October (4-5 months)

Flat-topped flower clusters (corymbs) in red, pink, yellow, white, or coral colors emerge on stiff stems; blooms prolifically.

Deadhead spent flowers to encourage continuous blooming through fall. Do not fertilize; excess nitrogen reduces flowering. Water only during drought.

5

Senescence & Winter Dormancy

November-March

Flowers fade, foliage may brown or die back depending on climate; plant prepares for dormancy.

Cut back dead foliage in fall or spring (spring in very cold climates). Leave seed heads in winter for wildlife and visual interest if desired. No watering needed.

Common Pests

  • Spray with water to dislodge; use insecticidal soap if severe. Increase humidity slightly and improve air circulation.

  • Improve air circulation and avoid overhead watering. Remove affected leaves. Apply sulfur dust or neem oil if needed. Avoid in overly humid conditions.

  • Ensure excellent drainage; reduce watering. Replant in dry, sandy soil. Do not mulch heavily around crown.

  • Spray with strong water stream or insecticidal soap. Rarely problematic on established plants.

Harvest Tips

For fresh flowers, cut stems in early morning when flowers are fully open but colors are most vibrant. Deadhead regularly to extend blooming season through fall. For dried flowers, cut when fully open and hang upside down in a warm, dry, well-ventilated location for 2-3 weeks. Dried flowers last for years in arrangements.
