Long blooming, large deep blue flowers. Foliage of Nepeta Blue Wonder is green-gray and aromatic. Its shorter stature (12") makes it suitable for the front of a border, or as a groundcover. Irresistible to butterflies.
Nepeta are smothered with blossoms in summer. Likes sun and dry conditions. One of the best plants to edge or underplant a rose bed. Cut back to the ground at the end of winter. Cats enjoy it as much as catnip.
Prefers dryish, not especially fertile soil. May benefit from gravel mulch. Spent flowers should be sheared off to promote rebloom. Cut back by 2/3 in July to promote reblooming in August to end of summer. Leave foliage on in winter and clean up in spring to help protect roots. Can be divided every 3 - 4 years in spring. Seeds are sterile.
