Growth Stages

1

Seedling/Transplant

3-4 weeks

Small rosette of gray-green leaves, compact low growth habit emerging

Keep soil lightly moist, provide bright light. Harden off transplants before planting outdoors.

2

Vegetative Growth

4-6 weeks

Mounding plant 12-18 inches tall, dense foliage fills in, no flowers yet

Water moderately, allow soil to dry slightly between waterings. Light fertilization with balanced fertilizer if desired. Pinch back tips early to encourage bushier growth.

3

Early Flowering

2-3 weeks

First small clusters of lavender-blue flowers appear at branch tips; buds forming along entire plant

Begin deadheading spent flowers to encourage continuous blooming. Increase watering slightly during heat. Stake if needed in windy locations.

4

Peak Bloom

8-12 weeks (June through September)

Plant covered in lavender-blue flower spikes from top to bottom, reaching 18-24 inches tall at maturity

Deadhead regularly for non-stop blooms through summer and fall. Minimal fertilizer needed. Mulch lightly around base to retain moisture in very hot climates.

5

Fall/Winter Decline

3-4 months

Flowering slows as temperatures drop; foliage may take on purple or bronze tones; dies back to basal foliage in cold climates

Stop deadheading in late fall to allow plant to harden off. Cut back dead stems in early spring before new growth emerges. In mild climates, may remain semi-evergreen.

Harvest Tips

For fresh use, pinch or cut flower spikes anytime during bloom for arrangements or drying. Best flavor and aroma in flower buds just before opening.

Fun Facts

  • 🌱 Walker's Low is named after and was first grown at the garden of Graham Stuart Thomas, a renowned English gardener and author, though the name references the lower-growing habit compared to other catmint varieties.
  • 🌱 Catmint has a fascinating history—it's been used in Europe for centuries, with some herbals dating back to medieval times, and was introduced to North America by colonists who valued it for both culinary and medicinal purposes.
  • 🌱 The plant's name 'catmint' comes from its strong attractiveness to cats, who are often enticed to roll in and rub against it; the response is similar to catnip but typically less intense.
