Rosmarinus Officinalis 'Tuscan Blue' (Upright Rosemary) is an erect shrub that grows 4-6 feet tall and spreads 4-5 feet. Bright lavender-blue flowers bloom among the fine, olive green foliage in the winter through spring. Flowers are larger than other varieties. As with other Rosemary, it is resistant to deer and rabbit predation, tolerant to salt spray, alkaline soils and drought. It features dainty spikes of lightly-scented blue flowers at the ends of the branches from early spring to early summer. It has attractive grayish-green foliage. The fragrant needles are highly ornamental and remain grayish green throughout the winter. This is a dense multi-stemmed evergreen woody herb with an upright spreading habit of growth. Leaves can be used as a flavorful spice in cooking. Takes to pruning well, but is equally wonderful when left in natural rustic form without pruning.
Rosemary Tuscan Blue prefers full sunlight and thrives in loose, well-drained, and neutral to slightly acidic soils. Water it deeply, regularly during the first growing season to establish an extensive root system; reduce frequency once established. Avoid excess winter moisture. It needs little care; maybe fertilized lightly in spring. It is pruned to maintain the desired shape.
