Maianthemum canadense (Canada Mayflower)

Maianthemum canadense (Canada Mayflower) is a vigorous rhizomatous perennial with pairs of large, oval, wavy-edged, shiny dark green leaves, 3 in. long (8 cm), arising directly from rhizomes. In late spring to early summer, sprays of tiny, white, star-shaped flowers are held on delicate stems just above the foliage. They give way to showy, ruby red berries in late summer. Spreading by underground roots, Canada Mayflower is a magnificent ground-covering plant.

Spreading by underground roots, Canada Mayflower is a magnificent ground-covering plant for woodland gardens. Do not plant it with other, less aggressive woodland wildflowers, as it would overwhelm them.

  • Grows up 4-8 in. tall (10-20 cm). Will spread quickly to form large colonies.
  • Performs best in part shade in average, medium moisture, well-drained soils. Tolerates heavy shade. Moist to slightly dry, humus-rich soils are preferred. Intolerant of heat and humidity.
  • Easy to grow, Canada Mayflower is a welcomed addition to shady gardens, cottage gardens, woodland gardens, naturalized areas or in moist areas near streams or ponds. Most effective as a groundcover.
  • No serious pest or disease issues. Keep an eye out for slugs and snails. Deer resistant.
  • Propagate by seed or by division.
  • Native to Eastern North America, Labrador to Georgia, west to Tennessee and Iowa.
