Rosemary

Rosemary is a woody, evergreen Mediterranean shrub with fragrant, needle-like silvery-green leaves and small purple, pink, or white flowers beloved by pollinators. It is slow-growing but long-lived and doubles as a striking ornamental. In Nordic climates it is commonly grown as an annual or overwintered indoors in a cool, bright location. It thrives in well-drained, lean soil and full sun.

Growing

Sow seeds very shallowly — no deeper than 0.5 cm — after cold-stratifying them in the refrigerator for 2–3 weeks to improve the naturally low germination rate. After stratification, move trays to a bright spot at room temperature; germination takes 10–20 days. Start indoors 8–12 weeks before transplanting outdoors. Transplant seedlings once night temperatures stay reliably above 5 °C into light, well-drained, and moderately fertile soil in the sunniest spot available. Space plants 25–35 cm apart with rows 50 cm apart.

Care

Water sparingly — rosemary is drought-tolerant and roots rot quickly in waterlogged soil. Feed lightly once established; avoid excessive nitrogen which reduces fragrance. No staking needed. Pinch shoot tips to encourage bushy growth. In Nordic climates, bring potted plants indoors before hard frosts to a cool, bright room or an unheated but frost-free greenhouse.

Harvest

Begin harvesting soft shoot tips once the plant is well established and actively growing. Snip stems up to 10–15 cm long; never remove more than one-third of the plant at a time to maintain vigour. Harvest is most productive when the plant is in active growth and flowering. Flowers are also edible and can be harvested as they open.

In the kitchen

Use fresh or dried rosemary needles to flavour roasted meats, root vegetables, breads, and marinades. The intensely aromatic leaves pair well with lamb, chicken, and potatoes. Infuse into oils or vinegars, or steep in hot water for an herbal tea. Edible flowers make a fragrant garnish for salads and desserts.

Storing

Store freshly cut sprigs wrapped in a damp cloth in the refrigerator for up to two weeks. For longer storage, dry bunches upside-down in a warm, airy spot until fully desiccated, then strip needles into an airtight jar away from light — keeps well for 12 months. Alternatively, freeze whole sprigs in a sealed bag for up to 6 months.
