Hairy alumroot is a compact native perennial that forms neat clumps of rounded, fuzzy leaves that stay green year-round. In summer, it sends up delicate spikes of tiny white or pink flowers that dance above the foliage. This well-behaved plant works excellently as a groundcover or edging plant in shaded areas.

Piedmont (includes Atlanta, GA)

Year-round

Hairy alumroot is a low evergreen mound that likes part shade and soil that holds some moisture but drains well. It handles Atlanta heat and humidity.

  • Plant in part shade or dappled light in moist, well-drained soil with plenty of organic matter.
  • Rated zones 3 to 8, and the source lists heat and humidity as things it tolerates.
  • Maintenance is low, and the source notes no significant pest or disease problems.
  • It handles some dry spells, but soil that goes fully dry makes it decline.

Mound the evergreen leaves along a front bed edge for steady year-round curb appeal.

Fall

Blooms and seed capsules carry into fall while the evergreen leaves stay put.

  • Flowers can continue into October and seed capsules form from July to November.
  • Leave the evergreen leaves in place, since they stay colorful through the cool season.
  • Fall is a fine time to plant, so roots settle before summer.

Winter

Hairy alumroot is evergreen, so expect leaves to stay through an Atlanta winter.

  • Rated hardy to zone 3, so Atlanta cold is no concern.
  • Leaves are described as bronze or purple and evergreen, so there is nothing to cut back.
  • Keep the bed from staying soggy, since it wants well-drained soil.

Spring

Spring is a good time to plant and to tuck in compost for the year ahead.

  • Plant in part shade in soil rich in organic matter.
  • Work in compost where soil is thin, since it prefers high organic matter.
  • Water during dry spells while new plants settle in.

Summer

Flower plumes show up in summer. Atlanta heat is tolerated, but fully dry soil is not.

  • Small white to pink flowers open from June on in North Carolina, so expect similar timing.
  • Give a drink in long dry stretches, because complete soil dryness causes decline.
  • Pick a spot with dappled light rather than hot afternoon sun.
