Arp Rosemary (Rosmarinus officinalis Arp) is a very cold hardy shrub Rosemary. It has a stiff upright growth habit and a mid-spring display of light blue flowers. Released by the National Arboretum. Drought resistant/drought tolerant plant (xeric). 36" tall x 36" wide.
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
Arp Rosemary (Rosmarinus officinalis Arp) is a bushy growing cultivar with stiff upright stems and soft blue flowers. Arp Rosemary has proven itself to be a cold hardy selection, extending the use of Rosemary beyond the mild winter areas of coastal CA and the Southwest. A great choice for hot walls and corners and other areas that get intense reflected heat. Plant in combination with other heat-loving plants like Zauschneria arizonica, Lavandula, and Calylophus and Yarrow. Released by the National Arboretum. Cutting propagated. 36" tall x 36" wide.

Planting Guides
To get established in USDA zones 5 & 6, Rosemary must be planted in spring or early summer, not in the fall. Protect your new plants over their first winter or two in your garden. Cover each plant with a generous pile of clean straw or pine needles. This allows the plant's crown (junction of root and branches) to mature and obtain maximum cold hardiness. View more Planting Guides, or download our complete Planting Guide for tips on caring for your plants when you receive your order, as well as planting instructions for Perennials, Spring-Planted Bulbs, Fall-Planted Bulbs, Cacti & Succulents, Xeric Plants and more.
