This newer, improved variety isn't all over the place, like traditional catmint can be. Instead, it matures into a tidy, compact mount you'll love to see covered in bright blue blooms all through summer. It grows wider than it does tall--almost doubling in width by year two--and its dense branches make a colorful border filler. The blooms will attract plenty of bees and hummingbirds you can watch at work. Of course, it also entices cats, who adore the scent that's released when the stems break. Creatures you're much less likely to see visiting Purrsian Blue are deer and rabbits, who generally steer clear of its scented foliage. Nepeta faassenii 'Purrsian Blue' PP24788
