Impatiens, or Impatiens walleriana, are annuals that grow and flower all summer long, and die back in the fall. Popular as bedding plants, they also do well in both hanging and standing pots and planters. Impatiens require specific soil, sunshine and water conditions.
Impatiens grow glossy green leaves and flowers in colors such as pink, white, purple and red. The plants grow to 2 1/2 feet in height with enough space -- and require large hanging baskets for balance and growing room.
Plant impatiens in quick-draining potting soil combined with peat moss or organic compost to maintain soil moisture and nourish the plants. Impatiens do best with partial or filtered sunlight.
Grown best in consistently moist soil, impatiens may suffer if the soil dries out. In outdoor garden areas, impatiens require 2 inches of water every week. According to North Carolina State University, though, potted flowering plants dry out more quickly than garden plants. Water hanging garden impatiens twice a week with 2 inches of water, and check them consistently for soil moisture levels.
Impatiens are more likely to dry out quickly if they sit in too much sunlight. To maintain the soil's moisture, ensure the pot hangs in a relatively shady location.
Organic mulch in the hanging basket helps maintain soil moisture and keeps impatiens from drying out. Gardeners should add 1 to 2 inches of organic mulch when they plant impatiens, and maintain this layer through the summer.
