#ProPlantTips For Care

This giant Catmint is a hardy Perennial that does best in full sun, but can tolerate part shade/afternoon shade in hotter climates. It thrives in well-drained soil of low to average fertility, handling rocky and sandy soils very well! Provide regular moisture during their first year but once established, Catmints are drought-tolerant. However, protect your investment with supplemental moisture during extended periods of drought and heat.

It is best to trim spent blossoms after flowering to induce a second bloom. Cut this plant back to the ground in late winter or very early spring. Great for fire-wise landscaping and xeriscaping dry sites in airy texture!

  • Full Sun & Some Part Shade
  • Tolerates Almost Any Well-Drained Soil Type
  • Moderate to Low Moisture Needs
  • Deadhead For Rebloom & Prune Back Mounds Late Autumn/Early Spring
  • Pest, Disease, Deer & Rabbit-Resistant
