Ornamental Features

Cool Cat Catmint has masses of beautiful spikes of lightly-scented lavender trumpet-shaped flowers with blue overtones rising above the foliage from early to mid summer, which are most effective when planted in groupings. Its attractive fragrant pointy leaves remain dark green in colour throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Cool Cat Catmint is a dense herbaceous perennial with a mounded form. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This plant will require occasional maintenance and upkeep, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting bees, butterflies and hummingbirds to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Self-Seeding

Cool Cat Catmint is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use
  • Herb Gardens
  • Container Planting

Planting & Growing

Cool Cat Catmint will grow to be about 24 inches tall at maturity, with a spread of 3 feet. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Cool Cat Catmint is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It can be used either as 'filler' or as a 'thriller' in the 'spiller-thriller-filler' container combination, depending on the height and form of the other plants used in the container planting. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
