For an easy-to-grow perennial that is drought and heat tolerant, pest and disease resistant, and blanketed with showy lavender blooms from spring to fall, ‘Walker’s Low’ catmint is a must-have choice. If you love the classic combination of lavender and roses but find lavender too difficult to grow in your area, it is a wonderful option. This herbaceous member of the Lamiaceae (mint) family originated in West Asia (Turkey and Iran), a cross between Nepeta racemose and Nepeta nepetella.

‘Walker’s Low’ catmint is cold hardy within the USDA Zones 4a-8b and should be planted in full sun or partial shade. It is adaptable to a wide variety of moist soil conditions, including clay, loam, sand and even shallow rocky textures providing good drainage with a neutral pH of (6.0-8.0). If planted in the south, it will benefit from some afternoon shade, and it may be bothered by high humidity.

In ideal conditions, ‘Walker’s Low’ catmint forms neat mounds as high as 2 feet with a spread of 18 to 36 inches. Its fragrant green leaves measure 1-3 inches in length and width. The leaves are simple, cordate – ovate in shape, arranged opposite with crenate margins. The leaves are fragrant when crushed. The stems are initially green, later becoming gray with a square cross-section. Showy blue or purple/lavender flowers are ½ inch long, trumpet-shaped, and arranged in loose clusters. Each flower has four stamens surrounded by lavender-blue petals. The flowers will rebloom in midsummer if cut back.

‘Walker’s Low’ catmint was first cultivated by Faassen Nurseries in the Netherlands and named for a garden called Walker’s Low. It is suitable for naturalized areas, on sloped surfaces within gardens for the blind, and drought-tolerant gardens. It can be placed in borders or collected into small groups of plants. ‘Walker’s Low’ catmint is attractive to bees, butterflies, and hummingbirds. It offers resistance to deer, drought, dry soil, and urban pollution. Walker’s Low catmint was the 2007 Perennial Plant of the Year.

Propagation & Planting:
‘Walker’s Low’ catmint should be planted in full sun or partial shade into soil that provides good drainage containing clay, loam, sand, or even shallow rocky texture with a neutral pH. The soil should not be excessively enriched, as flower production is reported to be better in more basic soil mixtures. Each plant should be allowed 3 feet or more of space. Some protection against late afternoon southwestern exposures should be considered when planting in Zone 8.

Because ‘Walker’s Low’ catmint is a hybrid, the flowers are sterile with no seed production. Division of an established bed is the primary method of propagation. This plant can be divided in the spring and will not take over a garden bed, unlike most plants in the mint family.

Basic Care Instructions:
Although ‘Walker’s Low’ catmint is drought tolerant, newly planted specimens should be provided consistent moisture of at least one inch per week until they are well established. The bed surrounding each plant should be mulched using shredded pine bark or pine needles. ‘Walker’s Low’ catmint does not require external bracing or support.

Fertilizing Instructions:
Newly planted beds of ‘Walker’s Low’ catmint may be promoted by the application of an organic mulch supplemented by an organic fertilizer during the first spring. Alternatively, slowly-released granular balanced fertilizer (10-10-10) may be applied several weeks after planting. Fully established plants need no supplemental fertilization.

Pruning Instructions:
Diseased or damaged leaves or stems may be removed at any time. Removal of spent flowers will promote reblooming throughout the summer. Shearing the bed may promote late summer blooming.

Pests & Disease:
‘Walker’s Low’ catmint is pest and disease resistant. Leaf spot occasionally occurs. This fungal disease is not considered serious enough to warrant chemical control practices. Leaf diseases are best avoided by watering the bed using drip line irrigation or watering early in the morning to allow the plants to dry quickly in the sunlight.
