Catmint, Dark Blue Panther
(Nepeta subsessilis) Perennial zones 4-9. Compact and tidy, this Japanese catmint and its mesmerizing blue blooms attract a range of pollinators. The plants reach just 12-20 inches tall and fit perfectly into beds, borders and containers. Nepeta subsessilis is also known as Japanese catmint. The blooms are larger than other types of catmints, and we especially appreciate the fragrance of the flowers. This bushy and colorful mounding plant is technically a perennial, but it will bloom in the first year and can be treated as an annual.
