Introduction to Rosemary
Rosemary is a classic Mediterranean herb that’s just as popular for its culinary uses as it is for its ornamental and pollinator-friendly qualities. With its fragrant, needle-like evergreen foliage and pale blue spring flowers, rosemary adds both structure and scent to UK gardens.
Perfect for herb gardens, gravel borders, or patio containers, rosemary thrives in sunny, well-drained positions and is a low-maintenance, drought-tolerant plant once established.
