#ProPlantTips for Care:

Catmint is a full-sun herbal plant and does best in very well-drained soil, but isn’t fussy about soil type. Provide regular moisture for young plants while first establishing, but after these are xeric and low-moisture need plants. For best results, provide supplemental moisture during extended periods of drought and in extreme heat and a 3-4 inch layer of arborist mulch chips for moisture retention. Deadhead for more blooms and prune mound back to a few inches in late fall once it has died back from frost.

  • Full Sun

  • Moderate to Low Moisture Once Established
  • Deadhead for Rebloom & Prune Late Fall After Frost
