Rosemary Arp

Rosemary ‘Arp’ (Rosmarinus officinalis 'Arp') is a cold-hardy, highly aromatic evergreen herb prized for its culinary versatility, ornamental value, and resilience in the landscape. Known for its upright growth habit and needle-like gray-green foliage, Rosemary Arp produces pale blue flowers from late winter through spring, attracting pollinators like bees and butterflies to the garden. This robust variety is one of the most cold-tolerant rosemarys available, thriving in USDA Zones 6–10 and making it a favorite for gardeners in cooler climates seeking year-round beauty and fresh herbs. Ideal for herb gardens, raised beds, borders, and containers, Rosemary Arp adds structure, fragrance, and culinary usefulness to any setting. Its aromatic leaves can be harvested year-round and used fresh or dried in meats, breads, oils, and marinades, while its bushy form adds texture and color to the landscape. Drought-tolerant once established, this rosemary variety thrives in full sun and well-drained soil, making it an excellent choice for rock gardens, xeriscapes, or Mediterranean-style plantings. Its deer resistance and low-maintenance nature further enhance its garden appeal. Rosemary Arp reaches 3 to 4 feet tall and wide, responding well to regular pruning, which promotes a denser shape and more flavorful foliage. Whether you’re planting it for its culinary benefits, fragrant foliage, or pollinator-friendly blooms, this hardy rosemary delivers dependable performance in both ornamental and edible gardens. With its superior cold tolerance and classic herbal aroma, Rosemary Arp is a must-have for gardeners who want beauty, function, and durability all in one plant.
