Rosemary ‘Arp’ (Salvia rosmarinus ‘Arp’)

Rosemary ‘Arp’ (Salvia rosmarinus ‘Arp’) is one of the most cold-hardy rosemary varieties available, prized for its fragrant evergreen foliage, upright growth habit, and exceptional culinary value. This versatile herb produces dense stems covered in aromatic needle-like leaves that can be harvested fresh throughout the growing season for cooking, preserving, and herbal uses.

The rich green foliage releases a classic rosemary fragrance and flavour that complements roasted vegetables, meats, poultry, breads, soups, and Mediterranean-inspired dishes. In addition to its culinary uses, Arp Rosemary serves as an attractive ornamental plant, adding texture, structure, and year-round interest to containers, herb gardens, and landscape plantings. Mature plants may produce delicate pale blue flowers that attract bees and other beneficial pollinators.

Arp develops a more upright and bushy habit than trailing rosemary varieties, making it ideal for herb gardens, raised beds, and decorative patio containers. Its improved cold tolerance has made it a favourite among gardeners looking for a rosemary variety that can better withstand cooler climates.

In Alberta, Rosemary ‘Arp’ is commonly grown in containers and can be overwintered indoors in a bright location. Its cold hardiness gives it greater resilience than many other rosemary varieties.
