Nepeta × faassenii

Nepeta × faassenii, a flowering plant also known as catmint and Faassen's catnip, is a primary hybrid of garden origin. The parent species are Nepeta racemosa and Nepeta nepetella. It is an herbaceous perennial, with oval, opposite, intricately veined, gray—green leaves, on square stems. The foliage is fragrant. It grows from 1–2 feet (30–61 cm) tall by 1–3 feet (30–91 cm) wide. The plant produces small but showy, abundant, two-lipped, trumpet-shaped, soft lavender flowers, from spring through autumn. Continued blooming is encouraged by deadheading. The seeds are predominantly sterile, and so the plant will not reseed as an invasive species, unlike some other nepeta species....read more on Wikipedia.
