Blue Catmint

Nepeta (ne-PEE-tah fah-SEN-ee-eye)

Family: Lamiaceae Non-native Herbaceous (1-3 ft)

Blue catmint is an herbaceous perennial, ground cover native to Europe and in the Lamiaceae (mint) family. It rapidly forms a clump 18 to 24 inches tall and spreading as much as 36 inches wide that blooms from spring into summer. It is a sterile hybrid plant, the result of a cross between Nepeta racemosa and Nepeta nepetella . It was first cultivated by Faassen Nurseries in the Netherlands. Site this plant in full sun to partial shade, especially in the South. It tolerates a variety of soil textures so long as they are well draining. Once established, blue catmint is drought tolerant. Shear after flowering to encourage repeat bloom. Propagate by division. Gray-green leaves and lavender-blue flowers are highly aromatic. It came to be called catmint owing to having a strong scent that cats find attractive. However, the scent deters deer. As a sterile plant it is unlikely to reseed. Grow blue catmint along a path, patio, or near an entrance to enjoy the aroma. Use it in a border or mass planted in a cottage or edible garden, or in a garden for the blind. It is also suitable for growing in a container or crevices in a rock wall. Insects, Disease, and Other Plant Problems: No significant problems. Some cultivars have shown excellent resistance to phytophthora. Other cultivars have shown poor resistance to pythium root rot.
