With a little extra care, Impatiens listed by Burpee can be grown successfully as house plants throughout the year.
If you plan to start your Impatiens from seed, sow the seed in a shallow tray of rooting mixture in the early Spring. They will require light to germinate so it is important that the seed just be gently pressed into your rooting mixture. Enough light will filter through this material to satisfy the light requirements. Carefully moisten the mixture with a fine spray of water and enclose the tray in a plastic bag and keep it at a temperature of at least 70 degrees. Avoid putting this in direct sunlight. Seedlings should emerge in 8 to 14 days and when they have reached about 1-1/2 inches in height, carefully transplant them to small individual pots filled with soil-based mixture. Impatiens will begin to flower in about 6 weeks. TEMPERATURE
Impatiens can be grown successfully in normal room temperatures with a humidity of at least 50%. If the temperature is above 75 degrees, they will require high humidity.
Plants should be placed on saucers of moist pebbles and should have their foliage misted daily.
