Catnip 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 and butterflies 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:
Catnip is recommended for the following landscape applications:
- Mass Planting
- Border Edging
- General Garden Use
- Herb Gardens
Catnip has masses of beautiful spikes of lightly-scented shell pink flowers rising above the foliage from early to late summer, which are most effective when planted in groupings. Its attractive small fragrant pointy leaves remain grayish green in color throughout the season. The fruit is not ornamentally significant.
Planting & Growing
Catnip will grow to be about 3 feet tall at maturity extending to 4 feet tall with the flowers, 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 is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. 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 species is not originally from North America. It can be propagated by division.
