Tuscan Blue Rosemary 
Rosmarinus officinalis 'Tuscan Blue'

USDA Plant Hardiness Zones: 7b-10a  Find Your Zone

Note:  For our customers who live and garden north of USDA Plant Hardiness Zone 7b, 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.

Special Attributes

Tuscan Blue is a perfect Rosemary for the southern states as it's more tolerable to heat and humidity. Throughout the year, this Mediterranean native has needle-like leaves that are very fragrant from afar. In spring, its small violet blue flowers cover the plants and attract butterflies and other beneficial pollinators. As with all varieties of rosemary, Tuscan Blue performs very well in both garden beds and pots that can be brought indoors for winter use for gardeners above USDA Zone 7b. Tuscan Blue rosemary has a lemony tang that goes along with its pine flavor and scent. It is not as harsh a taste as most other varieties and partners well with chicken, lamb, and fish. 

Growing 4 to 6 feet tall and wide, Tuscan Blue Rosemary is a great culinary herb for the garden, and the broad, bushy 'Tuscan Blue’ has the added appeal of distinctly sea green foliage and violet-blue flowers that make it suitable for use in the ornamental landscape. In the South, it is ideal for use as an accent, grouping or hedge in foundation plantings and landscape borders. Be sure to plant it near decks, patios, porches and other outdoor living areas where the fragrance and the pretty blue flowers can be enjoyed from up close. It is a natural choice for the herb garden and a fine addition to to coastal gardens, rock gardens, cottage gardens and fragrance gardens.


Cultural Preferences

Tuscan Blue 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 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.
