Impatiens are the go-to annual for shady spots — they thrive where sun-lovers fail, producing mounds of color with minimal effort.

Top Growing Tips

  • The premier shade annual — tolerates deep shade better than almost any other
  • Keep consistently moist — wilts quickly but recovers when watered
  • New Guinea impatiens tolerates more sun; standard types prefer shade
  • Pinch to promote bushier growth early in the season
  • Watch for downy mildew — improve air circulation if foliage yellows

Companion Planting

Good companions: hostas, ferns, begonias, caladiums

Avoid planting near: Full sun (causes wilting and sunscald)
