It's not always about new and snazzy. Sometimes you want a tried and true performer. Nepeta 'Walker's Low' was the Perennial Plant Association's Perennial Plant of the Year for 2007 for good reason. This excellent mounding border perennial has grey-green, aromatic foliage topped from June to September with a plethora of soft lavender-blue flowers. Great for the english garden look, the herb, butterfly or dry gardens. Named for the English garden Walker's Low and not a reference to its height.
