One of the best upright Rosemarys, Tuscan Blue can grow up to 6 feet tall. The lavender blue flowers contrast well with the green aromatic foliage. It is hardy to zone 8, and grows best under full sun.
“In our Lake Erie greenhouses, this cultivar produces its most vibrant foliage when given consistent morning light and steady warmth. When your order arrives, allow it to settle for 24 hours in indirect light before potting up into fresh, airy potting mix.”
