Bunchberry is a darling groundcover in the dogwood family. Its green, glossy leaves emerge each spring, followed by an exceptionally showy, four “petaled” creamy white flower that attracts pollinators to the shade garden. Interestingly, these “petals” are actually “floral bracts” and upon closer inspection, you’ll be delighted to see a cluster of tiny flowers at the center. In fall, the leaves turn a rusty hue and the flowers evolve into a tight little bunch of bright red berry-like drupes that are food for backyard birds.

Gardening with Bunchberry: Bunchberry will make an absolutely charming semi-evergreen groundcover in special, moist and humus-rich areas of your shade garden. Be sure to work lots of rotting bark, wood, etc. into the soil when planting - and to leave fallen fall tree and shrub leaves on the ground for the nutrients and acidity. In its natural habitat, it is common to see bunchberry growing on nurse logs in luxurious old-growth areas of the forest. Given these types of conditions, it spreads wonderfully by runners and seeds. If you’re lucky, it may even bloom twice a year (late spring and again in late summer).
