Rosemary (Salvia rosemarinus).

Rosemary seeds can be sown in early spring or indoors in late winter for a head start. To prepare the seeds, soak them in water for a few hours before planting. Choose a well-draining seed compost and fill small pots, seedling trays, or modules to about ¾ full. Sow the seeds thinly over the growing medium, ensuring light to germinate. Water gently, using a fine spray to avoid disturbing the seeds.

Grow the seeds in a warm location between 70°F to 80°F (21°C to 27°C). Covering the containers with clear plastic helps to maintain humidity and warmth. Monitor for germination and provide good light as soon as the seeds germinate. Thin the seedlings if necessary to prevent overcrowding and ensure each plant has enough space to grow.

Transplant the seedlings into individual pots or directly into your garden, ensuring well-draining soil and a sunny location with at least 6-8 hours of sunlight per day. Harden off seedlings grown indoors for two weeks before planting them out in the garden. Position in well-draining soil with a pH of 6.0-7.0 and space 2-3 feet apart. Water the plants to keep the soil moist but not soggy. Pinch off the tips of the plants to encourage bushy growth. 

Rosemary is a valuable kitchen herb for flavouring meats and its aromatic foliage make it a welcome addition to the garden and valuable flower for pollinators. It is a useful companion plant with pest-deterring properties conferred by its essential oils founded fragrance.
