‘Arp’ is regarded as the most cold hardy Rosemary variety, surviving temperatures to -10 degrees F. Originally found in Arp, Texas, this rosemary has thick, resinous, gray-green leaves, a faint lemony scent and an open growth habit. The shrub is dense, bushy, upright and aromatic. Arp leaves are dark green and leathery, up to 2 inches in length and they sport small, edible blue flowers in whorls up to 1/2 in long. Rosemary is widely used in cooking, especially Italian cuisine. Arp is not as harsh a taste as most other varieties and partners well with chicken, lamb, and fish.

Growing 3-5' feet tall and 4-5 feet wide, Arp Rosemary is ideal for use as an accent, grouping or hedge in in landscape borders and home foundation plantings. Plant it near patios, decks, porches and other outdoor living areas where the fragrance and the pretty blue flowers can be enjoyed from closer up. A natural choice for herb gardens and a fine addition to coastal areas, fragrance gardens and rock gardens. 

Note:  For our customers who live and garden north of USDA Plant Hardiness Zone 8a, where this Rosemary plant variety is not reliably winter hardy, you'll be happy to know it can be grown in containers that can be brought indoors during winter and placed back outside when temperatures warm up in spring.

Growing Preferences

Arp Rosemary is easy to grow in most any somewhat loose and moist to somewhat dry soil of average fertility and full to mostly sun. Plants will tolerate some shade but foliage won't be as dense. Grows well in full sun to part shade. It will tolerate dry periods, but flowers best with a moist soil. Can be pruned regularly for shaping or use in cooking.
