◦ Common Yarrow
Lookalikes 🔎
◦ Wild Carrot or Queen Anne’s Lace (Daucus carota): Leaves: Fern-like foliage with small, toothed leaflets and an edible, orange taproot. Flowers are small, white flowers in flat-topped umbels that are 2″ to 4″ diameter.
◦ Sweet Fennel (Foeniculum vulgare): Branching herbaceous perennial which grows 6.6′ height. Fennel has feathery, yellow-green leaves with needle-like segments and small yellow flowers that bloom in Mid to Late Summer.
◦ Poison Hemlock (Conium maculatum): Highly toxic herbaceous biennial that may be fatal if eaten, all parts of the plant are poisonous. The seeds containing the highest concentration of poison. Stems are green with red or purple spots and streaks, hollow and ridged, reaching 12′ high. The leaves are bright green, fern-like, finely divided, toothed edges, emitting a strong musty odor when crushed. Flowers are tiny, white, and arranged in small, umbrella-shaped clusters on the ends of branched stems The toxic white taproot could be easily mistaken for wild parsnips, which is not edible and dangerous.

▷ REPRODUCTION🌱
Sexuality: Hermaphrodite
Pollination: Pollinated by bees, butterflies, and other beneficial pollinators
Growth Rate: Fast
Propagation:
◦ Roots: Carefully dig up plant. Select healthy stems that are connected to roots, divide them in to separate plants, and cut off dead leaves and stems. Make sure there are a few roots for at least 1 stem. Replant each root system in the garden or in separate pots and water every 3 to 7 days until established.
Seed Germination: Cold stratification for seeds either dry or in a moist environment in the fridge for 30 days may speed up germination. Soil pH 5.5 to 7.0 at preferably 60°F to 75°F, kept moist, however not wet or dry. Plant seeds ⅛” deep, emerges 7 to 21 days after being sown. Germination rate of 75% to 96% (depending on producer).
Indoor Planting: Grow plant for 1 year prior to transplanting outside 10 weeks after last frost date.
Outdoor Planting: Plant seed 10 weeks prior to last frost date.
▷ REQUIREMENTS❤️
Sunlight, Water, Fertilizer, and Pruning ☀️💧✂️
Sunlight: Prefers 6 hours full sun; Excessive sunlight may cause the plant to wilt, place the plant in a location that receives shade during the hottest time of the day. Excessive shade causes stems and leaves to be weak and floppy and may encourage disease. Gradually introduce the plant to sunlight to help it acclimate
Note: Avoid aerial watering, which encourages fungal growth and disease.
Outdoor Watering: Water regularly during Summer (every 3 to 7 days), allowing for soil to dry on the top layer prior to more water. In the Winter, water infrequently when the plant is dormant (once every 2 to 3 weeks). Tiny pots and K-cup seed starters need water every day during Summer and every 2 days during Winter. Small pots require watering more often, especially if exposed to full sun, while large pots and shaded pots need less water.
Indoor Watering: Deep and infrequent, allowing for soil to dry on the top layer prior to more water.
Drought Resistance: Drought tolerant once established
Fertilizer: At the start of the growing season, apply fertilizer every 4 weeks to 6 weeks. Scatter evenly at the base of plants, avoiding clumps of fertilizer and preventing contact with stalks and stems. Large clumps of fertilizer won’t evenly supplement nutrients into the entire soil surface after it mixes with water from rain or irrigation. Fertilizer clumps around the base of plants make cause the main stalk to rot or have contact burns, which could damage or kill the plant. Do not throw fertilizer over plant tops, as the clumps of fertilizer caught in between leaf nodes and on foliage may either burn or rot the foliage.
Pruning: Avoid pruning during Winter as it may kill the plant. This same rule applies for the Fall in northern climates. Remove withered flowers, dead leaves, and leggy stems to enhance plant’s appearance. This also promotes new stems to appear with more leaves and flowers.
Soil, Planting, and Environment 🌄🏞️🏜️
Soil: Well-drained soil. Avoid soils that are rich and excessively moist or wet. Adapts to dry, sandy soil or damp, clay soil
pH: 5.5 to 7.0
Planting: When planting a potted plant, dig a hole that’s as deep as the pot and as wide as the root base. For plants with wide roots, dig a hole that is twice the width of the pot and gently space out the root system and then cover with soil to promote healthy growth. Burying tangled roots could cause health issues or stunted growth. The soil should be gently pressed in or watered in to fill the air pockets, preventing soil from collapsing in when watering or raining. Unplanted roots add to the stress of plants and could cause health problems or diseases. Cover every root with soil and smooth the soil’s surface.
Habitat: Native to temperate regions of the Northern Hemisphere, including North America, Asia, and Europe. Found in meadows, fields, dry slopes, and forests.
Temperature Preference and Temperature Tolerance🌡️
Temperature: 65° to 75°
Heat Tolerance: 85°F; 86°F and hotter may stress the plant and cause damage. Drought tolerant once established
Cold Tolerance: -10°F to -15°F. Mulch roots to retain water and to protect the root system from the cold during Winter. Keep dead leaves on the plant during Winter as a shield to protect the plant, then cut back in the Spring to promote new foliage growth.
Salt, Wind, and Pollution Tolerance 🧂💨 ☣️
Salt Tolerance: Low tolerance
Wind Tolerance: Low to moderate tolerance.
Pollution Tolerance: Highly tolerant of urban and inner city pollution

Diseases and Pests🐜🦠
Note: Proper care keeps plants resilient and healthy, preventing diseases and pests. This list details the potential threats, specific diseases and pests vary depending on environmental climate.
Diseases:
◦ Leaf Spot: Fungal infection that appears as small brown specks that can grow into larger lesions. These lesions are sometimes surrounded by yellow rings.
◦ Powdery Mildew: Disease caused by a fungus due to overwatering or overcrowding, making the plant vulnerable to other pests and diseases
◦ Root Rot: Disease that causes root system to deteriorate. Occurs when plant roots have constantly excessive or too much standing water around them. Common with indoor plants due to overwatering.
◦ Rust: This fungal disease is caused by more than 7,000 species of fungi. It affects the aerial parts of plants, most commonly the leaves, plus the stems, flowers, and fruit. Each type or plant rust has its own distinctive symptoms, such as bright red, orange, yellow, or brown spots on the leaves. As spores form, the spots turn reddish-orange and eventually black.
Pests:
◦ Aphids: Small, soft-bodied sucking insects which pierce plant tissues and draw out the juices.
◦ Spider mites: hey feed by bruising plant cells with their small, whiplike mouthparts and ingesting the sap. Spider mites produce a fine silk webbing, often found at leaf nodes or the undersides of leaves, which may kill plants or cause serious stress to them.
Animal Toxicity and Medicine Interactions ☠️❤️🩹
Thujone is a chemical compound found in specific herbs and is toxic in high amounts. Pregnant, breastfeeding mothers, and young children should avoid consuming thujone. Consuming excessive thujone may cause nausea, vomiting, abdominal cramps, dizziness, seizures, damage to the liver and nervous system, coma, or death. Thujone toxicity is higher with concentrated forms like teas, extracts, and oils. Thujone consumed from common culinary use of these herbs now and then is considered safe for consumption.
High Thujone Content: Wormwood (do not eat) and Mugwort
Moderate Thujone Content: Holy Basil, Sage, Yarrow
Low Thujone Content: Thai Basil, Sweet Basil, Thyme, and Oregano
Animal Toxicity: Toxic to dogs, cats, and horses.
