For an old-time favorite in modern dress, try one or two of the new dwarf varieties. They prefer a temperature a little on the warm side, plenty of fresh air, and good light, though some of the newer varieties do well in shady areas.
Seeds of impatiens are temperamental about germinating since they are sensitive to low temperature and a minimum of 70 F is necessary for germination. Sow seeds on moist sphagnum moss August first for winter bloom. Transplant to a mix of peatmoss, manure, and garden loam. Keep evenly moist but do not allow soil to become water-logged. Fertilize biweekly.
Impatiens may also be propagated by cuttings.
