Growing Impatiens in Zone 2A

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

Zone 2A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

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)

Harvest Timeline

Ornamental; no deadheading required — self-cleaning
