Year-round

Creeping spotflower is a low, spreading groundcover for spots that stay damp, like pond edges, ditch banks, and the low wet corners of a yard that never quite dry out.

  • It roots as it creeps along the ground, so a small planting fills in bare damp soil on its own within a season or two.
  • It wants full sun to light shade and soil that stays consistently moist. Letting it dry out between waterings slows it down.
  • It stays low, usually under a foot tall, so plan it as a groundcover along a wet edge rather than a focal plant.
  • Small yellow orange button flowers show up from mid summer into fall and draw in small pollinators.

Fall

Fall bloom continues until the season's first frost, which lands around November 3 in Memphis on average, and then top growth dies back for winter.

  • Enjoy the last flush of yellow orange blooms into October and early November before frost ends the bloom season.
  • After frost blackens the foliage, cut the dead top growth back to keep the bed looking tidy through winter.
  • This is also a good time to divide and share rooted sections before the ground cools further, since the plant is not reliably winter hardy through a Memphis winter.
  • Keep the soil from drying out right up until frost. A fall dry spell can stress the plant going into winter.

Cutting back the frost-killed foliage keeps a front-yard damp bed looking maintained instead of left to collapse over winter.

Winter

Winter in Memphis usually kills this plant's top growth back, and it may not reliably survive to resprout depending on how cold the season gets.

  • Leave a light layer of mulch over the crown after the ground freezes to help buffer any hard cold snaps.
  • Do not count on this groundcover coming back reliably after a Memphis winter. Keep a few rooted cuttings in pots indoors as backup if you want to be sure.
  • Hold off on any new planting or transplanting until spring. Winter ground is too cold for roots to establish.
  • Skip fertilizer entirely in winter. The plant is dormant or gone and will not use it.

A dead, frost-blackened patch near the front walk can look neglected all winter, so trimming it flush to the ground keeps the bed looking intentional.

Spring

Spring in Memphis wakes this groundcover back up once the soil warms, and it is the easiest window to divide or move sections before it fills back in for summer.

  • Memphis holds an average last spring frost around March 30, so wait until then before doing heavy digging or setting out new sections.
  • If the patch thinned out or went bare over winter, lift a few rooted stem pieces and press them into damp soil nearby to fill the gaps.
  • Keep the soil consistently moist as new growth picks up. A dry stretch in spring slows this plant down more than a cool night does.
  • Check the damp edges for slug and snail activity, which picks up on new spring leaves in wet beds.

Summer

Summer is peak growth and bloom for this plant in Memphis, but a hot dry stretch can pull moisture out of even a damp bed fast.

  • Watch the soil during any dry week. Memphis summers run hot and humid, but rain can skip a bed for a stretch and this plant does not tolerate drying out.
  • Flowers open from mid summer on, so this is when the small yellow orange blooms are most visible to people and to visiting pollinators.
  • It keeps spreading through summer heat as long as the soil stays moist, so trim back any runners that cross into a walkway or another bed.
  • A light layer of mulch around the patch helps hold moisture during hot stretches. Keep the mulch off the crown of the plant itself.

Trimming spreading runners back to the bed line keeps this groundcover looking intentional rather than unruly from the street.
