Nepeta - Catmint

Hardy zones 3 to 8 in full sun to partial shade unless otherwise noted. Protect young plant until established from cats. Yes I really did say cats. However the good news is - deer do not eat Catmint. Dead-heading prolongs the blooming. Plants are generally semi-evergreen ( deciduous in coldest climates ); they can be cut back to 1 inch above ground in early spring to enjoy the emergence of fresh new foliage.
