Walker's Low Catmint

Walker's Low Catmint is a versatile perennial, great for borders and containers. Its dense, spreading habit makes it an excellent groundcover, too. It reaches up to 2 feet in height and 3 feet in width at maturity. It reaches maturity approximately 1-2 years after planting. It boasts attractive grey-green foliage that emits a pleasant fragrance. The cool shade of the foliage creates a wonderful contrast against stunning purple flowers that bloom in summer and add a splash of color wherever they're planted.

• Herbaceous perennial
• Fast growth rate
• Suitable for borders, containers or as a groundcover
• Aromatic grey-green foliage
• Delightful purple flowers

Walker's Low Catmint is a tough, drought-tolerant plant. Hardy in zones 4-9, it will fare well in the North Texas climate. Prefers full sun, but doesn't mind partial shade. Plant it in well-drained soil.

Maintenance

Walker’s Low Catmint is loved for its incredibly easy-going nature, requiring very little to grow well. Here’s all it needs:

• Watering: Water regularly during the first growing season to establish deep roots. Once mature, Walker’s Low is highly drought-tolerant, thriving on minimal supplemental water. Deep, infrequent watering encourages stronger roots and better flower performance. Avoid overwatering.
• Pruning: Deadhead spent flower spikes regularly to extend the bloom season. After the first major flush of blooms in early summer, shear the plant back by about one-third to promote fresh foliage and a second wave of flowers that lasts until fall. In late fall or early spring, cut old stems down to just above the base to make way for new growth.
• Fertilizing: Walker’s Low thrives in lean or moderately fertile soil. Overfertilizing can lead to floppy growth, so be careful. Apply a light layer of compost or a small dose of balanced, slow-release fertilizer in spring for a gentle boost. 
• Mulching: Add a light 2-inch layer of mulch or fine gravel around the base to retain soil moisture and discourage weeds. Avoid piling mulch against the crown to prevent rot. In hotter climates, gravel mulch enhances drainage and reflects light, keeping foliage healthy.
• Winter care: Hardy and dependable, Walker’s Low survives cold winters with ease. After frost, cut back spent stems to tidy up the plant. New shoots reappear vigorously each spring, often larger and more floriferous than before.

Common Issues and How to Take Care of Them

Walker’s Low Catmint is resilient and pest-free, but a few manageable issues can occasionally appear:

• Root Rot: The most common problem, caused by overwatering or compacted soil. Ensure excellent drainage and avoid wet conditions.
• Powdery Mildew: Rare, but may occur in shaded or humid areas. Improve airflow, water early in the day, and prune after blooming to rejuvenate foliage.
• Floppy Growth: Can result from overfertilizing or insufficient sunlight. Full sun and lean soil keep growth dense and compact.
• Aphids: Occasionally gather on tender stems. Rinse with water or use insecticidal soap for quick control.
• Leaf Scorch: May appear during extreme drought. Provide deep, occasional watering to refresh the roots.
• Weakened Flowering: Typically due to aging clumps. Divide plants every 3-4 years in spring or fall to rejuvenate and restore heavy blooming.
