Catmint is well known and loved, and this genus contains tall and short plants, but all with the familiar aromatic foliage, grey-green and softly hairy, and spikes of small, funnel-shaped flowers, in the blue to purple range. All kinds like open, sunny places, with well-drained, even poor, soil.

Nepeta x faassenii is an aromatic plant with spikes of mauve- blue flowers rising above grey-green foliage over a long period. Has a relaxed, spreading habit.
