plant named ‘Cat's Meow’

Abstract

The new and distinct hardy perennial Catmint plant, Nepeta ‘Cat's Meow’ has a low growing, short and compact habit with upright and slightly decumbent stems. The foliage is intermediate is size and serrate. The flowers are sky-blue with persistent smoky-purple calyces.

Description

Botanical classification: Nepeta faassenii.

Varietal denomination: ‘Cat's Meow’.

BACKGROUND OF THE INVENTION

The new variety of Catmint, Nepeta ‘Cat's Meow’, was selected by Kevin A. Hurd from seed collected on Jul. 28, 2009 from Nepeta faassenii ‘Walker's Low’ (not patented). The pollen parent is unknown. The plant was originally given the breeder code of K9-07-02 and first evaluated in the summer of 2010, approved in final evaluation in the summer of 2011 and slated for later introduction. The new plant was selected based on the larger flowers, long blooming and compact traits. The new plant has been asexually propagated at a wholesale nursery in Zeeland, Mich. by tip cuttings with the resultant plants remaining identical to the original plant, stable and true to type in successive generations.

SUMMARY OF THE INVENTION

Nepeta ‘Cat's Meow’ is different from its parents and all other Cat Mint known to the inventor. In comparison to the female parent ‘Walker's Low’ the new plant is considerably shorter and more compact. The nearest comparison variety is Nepeta ‘Novanepjun’ U.S. Plant Pat. No. 23,074. ‘Cat's Meow’ is taller and more sprawling in habit than ‘Novanepjun’. The new plant is taller, less decumbent and more upright than Nepeta ‘Psfike’ U.S. Plant Pat. No. 18,904 and is shorter than ‘Junior Walker’ (not patented) , ‘Blue Dragon’ U.S. Plant Pat. No. 22,334 and ‘Six Hills Giant’ (not patented) and ‘Purple Haze’ U.S. Plant Pat. No. 23,180. In comparison to ‘Purrsian Blue’ (co-pending application), the new plant ‘Cat's Meow’ is slightly taller, slightly more spreading in habit with serrate leaf margins on larger leaves and sky-blue flowers compared to the serrate leaves with rounded teeth margins and periwinkle blue flowers. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with changes in the environment such as light, temperature, water and nutrient availability, etc. without a change in the genotype of the plant. Nepeta ‘Cat's Meow’ is unique from all other Catmint known to the inventor in the following combined traits:

• • 1. The habit is low growing, short and compact upright and slightly decumbent stems.
  • 2. Foliage is moderate-sized and serrate.
  • 3. Flowers are sky-blue with persistent smoky-purple calyces.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant Nepeta ‘Cat's Meow’ are of a two-year old plant in a full sun display garden in Zeeland, Mich. and demonstrate the special unique aspects of the new plant. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, temperature, source and direction may cause the appearance of minor variation in color.

DETAILED PLANT DESCRIPTION

The following descriptions are based on a two-year old plant of Nepeta ‘Cat's Meow’ grown in a full-sun display garden in sandy loam with supplemental water and fertilizer as needed. The color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype.
