Sweet Annie

Sweet Annie (Artemisia annua) is a vigorous, re-seeding annual herb in the daisy family, prized for its feathery, fern-like foliage and masses of tiny pale-yellow flowers. Its intensely sweet, camphor-like fragrance persists long after the plant is cut and dried, making it a staple of dried and fresh floral arrangements. Given full sun and warm conditions it rapidly grows into a towering plant up to 180 cm tall. It thrives in open ground or large raised beds with well-drained soil.

Growing

Start seeds indoors 6–8 weeks before transplanting, once nights reliably stay above 8 °C. Press seeds onto the surface of moist seed-compost and do not cover — seeds require light to germinate. Keep the tray at 15–20 °C; germination occurs within 7–14 days. Thin or prick out seedlings and grow on in bright light. Transplant to final positions when soil has reached at least 15 °C, spacing plants 25–35 cm apart. Sweet Annie also self-seeds freely from established plants — mark germinating volunteers early and thin to 30 cm spacing.

Care

Water regularly during establishment, then reduce to moderate irrigation; Sweet Annie tolerates short dry spells once established. Feed monthly with a balanced fertiliser to sustain vigorous growth. No staking is typically needed in sheltered sites, but in exposed locations or where plants exceed 150 cm, support with canes or a ring stake. Remove any dead or damaged stems promptly to maintain airflow. Allow a few plants to set seed at season's end to encourage natural self-seeding.

Harvest

Harvest stems for fresh use once flower buds are fully formed but before the majority open. For drying, cut long stems early in the day when aromatic oils are at their peak, bundle loosely, and hang upside down in a warm, well-ventilated spot. Harvest window extends over approximately 4 weeks; repeated cutting encourages new lateral growth. The fragrance intensifies and persists through drying.

In the kitchen

Sweet Annie is primarily an aromatic herb and ornamental rather than a culinary green. Use dried stems and foliage in wreaths, swags, potpourri, and dried floral arrangements. A small amount of fresh foliage can be infused into teas or used as a tisane; the flavour is intensely bitter and sweet, so use sparingly.

Storing

Dried bundles retain fragrance for 12–18 months when stored away from direct light and moisture. Keep in a dry, ventilated room or paper bags — never sealed plastic, which traps humidity and causes mould. Fresh-cut stems last 7–10 days in water at room temperature.
