A fast-spreading, low-growing perennial groundcover that blankets the ground in tiny two-lipped lavender-blue flowers from late spring into summer -- equally at home underfoot between pavers or filling in a shady, moist corner of the garden.

Mazus reptans, commonly called creeping mazus, is a mat-forming herbaceous perennial native to East Asia that has become a popular, well-behaved groundcover across much of the eastern and midwestern United States. Its wiry stems creep along the ground and root as they spread, quickly knitting together a dense, ground-hugging carpet of small, glossy, toothed leaves that stay green through most of the growing season and often persist into winter in milder climates. From late spring into summer, the foliage is covered in small, two-lipped, orchid-like flowers in shades of lavender-blue, each marked inside with white and yellow. Reaching only a few inches tall but spreading a foot or more, it tolerates light foot traffic and occasional mowing, making it a favorite for filling gaps between stepping stones, softening the edges of a path, or replacing turf in a small, moist, partly shaded area.

Pros

  • Thick, fast-spreading mat smothers weeds and fills bare spots quickly
  • Long bloom season of tiny lavender-blue flowers from late spring into summer
  • Tolerates light foot traffic and an occasional mowing
  • Low-maintenance with no serious pest or disease problems

Cons

  • Spreads aggressively by rooting stems and can escape its intended area if not edged
  • Prefers consistently moist soil; may thin out in hot, dry spells
  • Classified as naturalized/weedy in parts of the eastern U.S.
Highlights A tough, fast groundcover for small or awkward spaces -- between pavers, edging a path, or filling a damp low spot -- that rewards minimal care with months of tiny lavender-blue blooms.

Pairs nicely with other shade-tolerant groundcovers and early bulbs -- try it with hostas, astilbe, ferns, or creeping thyme, or let it fill in around spring-blooming bulbs like crocus and daffodils once their foliage fades.

Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
