Nepeta Walkers Low
As is expected from a Nepeta, "Walker’s Low" has soft, grey-green foliage, a long, repeat-blooming season and few problems or maintenance requirements.
The name "Walker’s Low", supposedly refers to a place in England, not its growth habit. ‘Walker’s Low’ can easily reach 2 ½ to 3' tall and equally as wide, in warm areas. It has deep lavender-blue flowers that will bloom profusely in early summer and then sporadically throughout the growing season. If sheared back after the first flush of bloom, another significant bloom can be expected, but your plant will not get as large as it might. Shearing also refreshes the foliage.
An aromatic member of the mint family, Nepeta ‘Walker’s Low’ is not attractive to deer. In fact, even cats are indifferent to it. However, it is a magnet for butterflies, hummingbirds and especially bees.
