James H. Schutte

Family

Lamiaceae

Botanical Name

Rosmarinus officinalis 'Tuscan Blue'

Plant Common Name

Rosemary, Tuscan Blue Rosemary

General Description

Rosemary is one of the great culinary herbs for the garden, and the broad, bushy cultivar 'Tuscan Blue’ has the added appeal of distinctly sea green foliage and violet-blue flowers. So, its ornamental appeal nearly matches its herbal offerings.

Throughout the year, this Mediterranean native has needle-like leaves, which are potently fragrant from afar. In mid-spring to early summer, its small colorful flowers cover the plants. They are two-lipped, cool violet blue and attract bees and butterflies in droves.

Rosemary will prosper in locations with full sun and perfectly drained average to poor soil. This multipurpose herb also works well in containers or mixed borders. It is technically a subshrub, which means it is woody, and can also be planted and pruned as a shrub where fully hardy.
