Rosemary 'Tuscan Blue in the garden.

Rosmarinus officenalis, or Rosemary as it is commonly known is an evergreen shrub of the mint family, Lamiaceae, noted for the fragrance of its leaves. Rosemary grows wild in the Mediterranean region where it can grow from from 2 to 6+ feet high. It bears shiny, dark-green leaves that are grayish-white beneath and small, white, blue or violet flowers. In masses, blossoming rosemary looks like blue-gray mist blown inland from the sea. Its name translates from Latin as sea dew from the words "ros" for dew and "marinus" for the sea, probably in reference to its inhabiting sea-cliffs. Uses for Rosemary its use fresh or dried as an herb for seasoning, as an ingredient in perfumes. as a moth repellant, and to brew an herbal tea. Europeans carried rosemary at weddings and funerals because they believed it would aid their memories.

There are many cultivars of Rosemary that are grown for their culinary uses, form and flower color. There are cultivars that are prostrate, others upright and a number that are sprawling; all generally have a moderate growth rate and require little water (outside of desert areas) and fertilizer once established. Flowering is primarily in the late winter and early spring with intermittent bloom through the year. A second peak bloom often repeats in the fall. The flowers attract bees. Rosemary tolerates moderate frosts down to about 15°F but are a not a good plant for cool wet locations prefering mild and warmer climates in a sunny location in well drained soils. They tolerate reflected heat, seaside conditions and drought. They are resitant to predation by deer and rabbits and are a good choice for erosion control on a slope. Plant approximately 2-5 ft apart depending on the variety for good coverage.

A prostrate evergreen shrub to 2 feet tall by 6-8 feet wide with bright green foliage and blue violet flwoers in late winter through early spring with sporadic bloom year-round.

The bright green foliage is covered during the spring bloom of pale blue flowers with sporatic bloom through fall. Plant in full sun. Drought tolerant. Deer resistant. This variety is known as Santa Barbara Rosemary as it was discovered here in the Santa Barbara garden of Lockwood and Elizabeth De Forest. The de Forest's speculated that the plant was a spontaneous hybrid between an upright plant that was planted in their garden in 1927 a prostrate rosemary that was planted in the 1930's. Elizabeth deForest, in an article for Pacific Horticulture in 1976 described the pale blue color as "the color of the old French air force uniform". She mentions in this article that it became the most common of prostrate Rosemary cultivars in Santa Barbara.
