Nepeta × faassenii
This hybrid catmint is widely grown for long bloom and aromatic foliage. It is a sterile cross between Nepeta racemosa and Nepeta nepetella. It stands out for reliable flowering from late spring to early fall when plants are sheared after the first wave. It performs best in full sun with average, well drained soil. It tolerates dry conditions once established but is not as drought tolerant as some other Nepeta. Plants resist browsing by deer and rabbits. In the Deep South it benefits from light afternoon shade.
