This very dwarf, trailing variety is prized for its tidy, obedient habit, only spreading 12 inches. The deep, pewter-green, needlelike foliage will spill over low garden walls or containers in manageable, mounding billows. Medium blue, bell-shaped blooms cover the aromatic foliage in May. As flavorful as other rosemary varieties, use its leaves to season your favorite recipes. Hardy in zone 8 and above. Attractive in hanging baskets. Needs good drainage. Perennial.
