Description

Impatiens are popular flowering annuals for partial to full shade. There are two forms, standard types and New Guinea Impatiens. New Guineas like the Divine series have larger flowers and dark green to bronze leaves. Both forms are ideal for garden beds, patio pots, mixed containers, and hanging baskets.

How to Plant

  • Standard Types - Seed should be started in a sterile starting mix kept at 70-75° F, 10-12 weeks prior to last frost. Seeds benefit from light, so do not cover with soil and take care when watering. Expect germination in 15-20 days. Transplant to a larger pot when there are 2 sets of true leaves and harden off prior to planting outdoors.
  • New Guinea - Seed should be started in a sterile starting mix kept at 75-80° F at a depth of 1/8", 10 weeks prior to last frost. Expect germination in 15-20 days. Transplant to a larger pot when there are 2 sets of true leaves and harden off prior to planting outdoors.

Maintenance

Easy-to-grow and best in a moist, well-drained soil. Using an organic mulch helps keep soil moist. Plants can be cut back by up to ½ their height if they become too tall. 

Fertilizer Recommendations

Both types of impatiens are moderate feeders that benefit from occasional fertilization. Use low rates of Algoplus Flowering Plant 4-6-7 Liquid FertilizerNeptune Fish & Seaweed Fertilizer 2-3-1, or Osmocote 14-14-14.

Common Problems

Usually free of problems, although downy mildew disease is becoming more common on standard Impatiens. New Guinea Impatiens are not affected by this disease. If plants are infected, they cannot be cured and should be removed and disposed of. If Impatiens are attacked by downy mildew in the garden, grow non-susceptible plants instead.

Alternative Products

In areas where downy mildew disease is a problem, use other brightly-colored shade annuals instead of standard Impatiens. Plants like Santa Cruz Sunset BegoniaChocolate Covered Cherry Coleus, and New Guinea Divine Mystic Mix Hybrid are good replacements.

Complimentary Products

Actinovate Organic Fungicide or Liquid Copper Fungicide can be used preventatively, to reduce potential problems with downy mildew disease.

Product Recommendations

Use Al's Flower Pouch as an alternative to hanging baskets.

Impatiens Facts

Claude Hope was a plant breeder who worked with Impatiens walleriana, which as a wild plant grows about 3 feet tall and flowers only sparsely. It was Claude's breeding efforts that created varieties that were compact, flowered strongly, and had an expanded color range. His first introduction was the Elfin series in 1969. It was replaced with the Super Elfin series, which remains on the market today.
