Nepeta 'Joanna Reed'

Common name: 'Joanna Reed' catmint

Botanical name:Nepeta 'Joanna Reed'

Flowers: Tall spikes of small flowers, darker purple/blue than most catmints.

Foliage: Grayish green, small, held opposite on stems, scented. New growth quickly overtakes and hides spent flowers.

Habit: Upright herbaceous perennial to 3 feet tall and wide.

Season: Summer and autumn, for flowers.

Origin: A natural cross between Nepeta siberica and N. faassenii. The late Joanna Reed, a Pennsylavania gardener, discovered it in her garden and it was named for her by David Culp, who introduced it through Sunny Border Nurseries.

Cultivation: Grow in full sun and average, well-drained soil. Tolerates some drought once established. Do not fertilize catmints; it will create a surge of growth that results in floppy stems. 'Joanna Reed' is a sterile catmint, meaning it does not produce seeds so it will not "volunteer" throughout the garden. Propagate through stem cuttings or division in spring. Deer resistant. USDA Zones 3–8.
