Nursery contributed plant descriptions

Rosmarinus officinalis ‘Arp’ is the hardiest of rosmaries. It has a strong, upright habit with fragrant, grey-green to bluish green foliage perfect for use in the kitchen. It is best known for having especially excellent winter hardiness in comparison to other cultivars of rosemary. In harsh winters all rosemary will likely die but in moderately cold winters 'Arp' will usually survive when other cultivars perish. The best flavour and plant longevity will be in hot dry spots with poor soil.
This U.S.D.A. introduction is a full zone hardier than most varieties, with the same wonderfully pungent gray-green leaves, sky-blue flowers, and upright growth habit. S/M-D/GDr
That's Arp, Texas, where one ol' specimen is still growing strong at 80. An upright shrub with gray-green foliage and light blue flowers, 'Arp' is most at home inland, where it opens outward in the heat; on the coast its habit is more compact, but still handsome.
Mounding perennial herb with soft blue flowers in late winter..having a fine fragrant leaf and probably the hardiest of the Rosemarys..culinary herb for cooking.
Selected as a hardier clone with a more open habit.
