Good Companion Plants for Catmint

 At this time, I’ve planted over 100 different types of plants in my Zone 6 garden!  As different plants start to thrive, I’ll highlight them here ~ & one of the best performers I’ve got right now, in spite of a wet spring here in Bend, Oregon: is the fast-growing catmint, also called Walker’s Low.  You see this plant all over town, & landscapers love it: because it’s reliable & easy-to-grow, with pretty purple flowers.  It’s also a long-bloomer, showing off from mid-spring thru the end of fall.  And it’s drought-tolerant!  Here, we’ll discover some “Good Companion Plants for Catmint,” that provide a great backdrop for this purple stunner.

Quick Overview of Catmint

  •  Common/Other Names for Catmint: Nepeta, Walker’s Low, or “Baby Blue”
  • Hardiness Zones: 4-8

  • Growth Rate: FAST
  • Mature Size: 1-2 feet tall, 1-3 feet wide
  • Preferred Sun Exposure: Full sun is where they’ll perform best; I have some planted in partial shade & they don’t get as big
  • Bloom Time: Spring, summer, & in some climates (like my Zone 6) thru fall
  • Easy to Grow? SO EASY. Catmints thrive on neglect ~ so even beginning gardeners should be fine with them. I’ve planted over 8 catmints all over my garden, in various sun exposures…I never fertilize them, & they’re ALL doing well.

  • How Much Water Do Catmints Need? After the first year, water minimally; they prefer drier conditions. Full sun & very little after the first year will actually make them stronger.

Examples of Companion Plants for Catmint

 When you’re thinking of great companion plants for Walker’s Low, think of all the colors that look best next to purple: hot pink, light pink, white, other purple plants, blue (like soaring delphiniums), orange, & yellow (such as the easy-to-grow forsythia).  Colors that don’t look good next to purple, in my opinion, are anything RED: it’s just not a great pairing.  You can also place leafy shrubs or climbing vines around your catmint, to great a sea of green around the purple. 

Great Plant Pairings with Catmint:

  • Pink roses, white, blush, orange, or yellow roses;
  • Beautiful climbing roses;
  • Hot pink dianthus (though note that because it’s a low plant, it might eventually get overshadowed by the catmint);
  • Tall flowering plants like foxgloves & delphiniums, gorgeous peonies, or even show-stopping dahlias;
  • Tall native grasses, such as popular Karl Foerster, or other ornamental grasses offer an ethereal backdrop to the grounded Nepeta/catmint;
  • Tall yellow shrubs like the easy-to-grow Lynwood Gold” Forsythia;
  • Colorful annuals like snapdragons (whose pastel color palette goes perfectly with purple), vibrant daisies, violas, pansies, or zinnia ~ just plant the annuals far enough away from the catmint so they don’t get crowded out (catmint’s tend to S-P-R-E-A-D O-U-T);
  • Catmints attract bees & all kinds of wildlife: consider placing them next to fruit trees or your veggie garden in order for pollinators to spread love to your “Edible Garden;”

If you’re on the fence about adding catmint to your yard, especially if you’re a novice gardener: I say, go for it!  Start with one or two, & once you see how easy they are to grow, you may decide to buy a few more.  They give you the look of French lavender ~ but are far easier to grow, & have a much longer bloom season.

Happy Gardening!
