This hardy perennial is drought-tolerant, attracts pollinators, and provides long-lasting color throughout the summer months. It's a reliable garden staple that requires minimal maintenance once established.

Growing Conditions

☀️

Sun: Full sun, 6-8 hours daily; tolerates partial shade but blooms best in full sun

💧

📏

Spacing: 12 inches

📅

Days to maturity: 60-90 days from transplant to first bloom; reaches full maturity by second year

🌱

Planting depth: Surface sow seeds (light required for germination); plant transplants at soil line

Soil

Growth Stages

Seedling

2-3 weeks

Tiny seedlings with fine, thread-like cotyledons emerge. Early foliage is delicate and feathery.

Keep soil consistently moist but not waterlogged. Provide bright light and good air circulation to prevent damping-off. Thin seedlings to proper spacing.

Vegetative

4-6 weeks

Plant develops dense mounds of finely dissected, feathery green foliage. No flowers yet, but structure fills in.

Water moderately; allow soil to dry between waterings. No fertilizer needed—yarrow prefers lean conditions. Pinch back early stems to encourage bushier growth.

Flowering

6-10 weeks or longer

Golden-yellow flower clusters (corymbs) appear at stem tips, starting to open in mid-summer. Blooms are abundant and attract butterflies and bees.

Deadhead spent flowers to encourage continuous blooming. Water at soil level to keep flowers dry. No staking usually needed.

Peak Bloom

4-8 weeks

Plant is full of bright golden flowers in dense, flat-topped clusters. Color is vivid and attracts numerous pollinators.

Continue deadheading for extended bloom. Cut flowers for arrangements; they dry beautifully. Monitor for pests, though yarrow is generally pest-resistant.

Senescence & Winter Dormancy

4-6 months (fall through spring)

Flowers fade, foliage may brown; plant dies back as temperatures cool. Dried seed heads remain ornamental through fall.

Leave foliage intact over winter for insulation and wildlife habitat. Cut back to ground level in early spring before new growth. No watering needed.

Harvest Tips

Cut flowers for fresh arrangements when fully open but before petal edges brown. Harvest in morning after dew dries. Cut at soil level or just below the lowest florets. For drying, cut stems when flowers are fully open, hang upside-down in bundles in a warm, dry, dark location for 2-3 weeks. Dried flowers retain color well.
