2007 Perennial Plant of the Year: Nepeta ‘Walker’s Low’

Nepeta ‘Walker’s Low’ is the Perennial Plant Association’s 2007 Perennial Plant of the Year. The name of this blue-flowering perennial can be a bit deceiving: it’s named for an Irish garden, rather than a low-growing habit. It actually grows about 3 feet tall.

Introduced in 1988, Walker’s Low catmint is a long bloomer with blue-violet flowers and attractive grey-green foliage.

A note about the botanical name

Some experts believe ‘Walker’s Low’ Nepeta to be a hybrid between two species, nepetella and racemosa, and it is often labeled as this hybrid species (x faassenii).

Other authorities place it under one parent (racemosa).

Whatever true origin of this cultivar, its parent species are native to the Caucasus and northern Iran, which accounts for this cultivar’s ability to weather heat and drought.
