Overview

Rosmarinus traditionally refers to the group of evergreen, woody, aromatic shrubs commonly called rosemary. These plants are notable for their needle-like leaves and scented foliage. They belong to the mint family, and are widely cultivated around the world for flavoring, fragrance and garden ornament. The name appears in many horticultural and culinary contexts even as botanical classifications have evolved.

Characteristics

Members of Rosmarinus have narrow, leathery leaves coated with tiny oil glands that release a strong fragrance when crushed. Flowers are typically small and tubular, often blue to purple in wild forms, and attractive to pollinators. Growth habit ranges from upright shrubs to prostrate groundcovers; many cultivated varieties differ in size, foliage color and flower shade. For more on the plant type, see woody perennial herb.

Taxonomy and history

Historically placed in the genus Rosmarinus within the family Lamiaceae, rosemary has long been recognized in Mediterranean cultures. Modern molecular studies have shown close relationships with sages, and many taxonomists now include these species in the genus Salvia. Despite this change, the traditional name Rosmarinus persists in gardening, cooking and trade.

Uses and cultivation

Rosemary is widely used for culinary seasoning, aromatherapy, and as an ornamental. It tolerates dry, well-drained soils and sunny sites, making it a common choice for Mediterranean-style gardens and xeriscaping. Typical uses include:

  • Fresh or dried herb in cooking and food preservation.
  • Essential oils and perfumes derived from leaf extracts.
  • Landscape uses as hedging, espalier, or groundcover varieties.

Notable facts and distinctions

Rosemary has cultural associations with memory and remembrance in several European traditions and appears in ancient herbals. It is drought-tolerant, deer-resistant, and useful for attracting bees. Native to the Mediterranean region, the plant thrives in climates with mild, wet winters and hot, dry summers; for more on its native range see Mediterranean.
