Catmint 'Walker's Low'

Nepeta × faassenii 'Walker's Low'

Preview: plant data is awaiting horticulturist review. A professional horticulturist hasn't reviewed our plant table yet. Lists still follow fixed rules for zone, sun, pets, deer and invasive status.

Nepeta × faassenii 'Walker's Low' is a fast-growing perennial for gardens in zones 3–8. Expect 2–2.5 ft of height and 2.5–3 ft of spread; our lists space it 2.5 ft apart. It does best in full sun to part sun with little water once established. Expect blue flowers in May to September. In a FloraVista list it usually plays the filler role: a flowering plant that fills the middle or front of the bed. Deer usually leave it alone, and it is toxic to dogs and cats. Our rules leave it out of lists in Florida and the Gulf, where summer heat, humidity or mild winters hold it back even inside its zone range.
