One of my favourite plants. This variety is huge - it gets about 80 cm tall and wide. I just moved it this spring so it is smaller than it was last year, but I'm sure next year it'll be crowding out everything around it.
Catmint looks so nice along a sidewalk or patio because it spills over and softens the edge. It also looks great with roses or lady's mantle. If you don't have enough space for this variety, 'Walker's Low' is smaller and more well-behaved.
It likes full sun and is drought tolerant. It blooms from now until frost, which is one reason why I like it so much. It can be cut back for even more flowers later in the season.
