Scientific Name (Genus/Species): Nepeta parnassica

Family: (Lamiaceae)

(P) to 5′.  Tall Greek Catmint.  Albania and Greece.  Truly the biggest and most impressive Catmint we have ever seen.  Although native to the dry, rocky meadows of the Balkan Peninsula it seems to luxuriate and thrive in our fertile garden soil.  The strong, upright stems bear fragrant, greyish green foliage and produce dense whorls of rich lavender-blue flowers in crowded, elongated spikes.  This is a “sturdy item,” that does not need to be cut back halfway through the season.  Blooms mid-summer onwards and will add stature, colour, and fragrance to the late summer garden.  Sun, well-drained soil.  4 & T2
