Double impatiens are shade-loving annuals with brightly colored, bunchy flowers that resemble miniature roses. Set off by dark green foliage, these popular bedding plants are enjoyed for a range of warm bloom hues in the red and orange family, as well as white and even lavender. An easy annual plant to care for, double impatiens will beautify and fill out your summer display.
Choose a location with good drainage. Double impatiens love shade but will tolerate filtered light for a stretch of up to four hours in the morning, if it is not direct. Harsh, direct sunlight and heat are the enemy of these tender plants.
Add a slow-release fertilizer to the soil and work until well incorporated. Fertilizer applied before planting will gradually feed plants over a longer period of time, promoting annual blooms throughout the season.
Allow double impatiens starts to harden, or acclimate, to the outdoor location you choose before planting. Set starts in the shade and then into filtered sunlight for short visits over a period of several days.
Plant double impatiens 8 to 10 inches apart to allow for mature growth. Taller species might require up to 18 inches between plants to reduce a leggy or spindly tendency because of crowding.
Water well after planting. Double impatiens often require weekly watering in dry or hot weather.
Pinch off double impatiens plants that are growing tall and spindly looking. This will create a bunchier plant with more blooms.
