At last – Impatiens highly resistant to Impatiens Downy Mildew

Downy mildew is a devastating disease that can quickly kill an entire planting of impatiens or basil. This disease spreads easily and quickly, and no sweet basil or traditional impatiens were resistant to it until plant breeders changed that in 2018.

Traditional impatiens, the go to plant for shady sites, succumbed to a similar but different (from basil) form of downy mildew and many garden centers turned to New Guinea impatiens, a larger plant with darker foliage, and stopped selling the traditional Impatiens walleriana. 

Home gardeners that did find traditional impatiens often planted them to only find in a few weeks, leafless diseased plants that were soon dead from impatiens downy mildew.

An exciting variety featuring volumes of cherry red blooms on a mounded habit, from late spring until fall; well branched plants bounce back very well after a wilt; excellent shade color for the garden or containers

Ornamental Features

Bounce™ Cherry Impatiens is covered in stunning cherry red round flowers at the ends of the stems from mid spring to early fall. Its pointy leaves remain green in color throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Bounce™ Cherry Impatiens is a dense herbaceous annual with a mounded form. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

This plant will require occasional maintenance and upkeep, and should not require much pruning, except when necessary, such as to remove dieback. It has no significant negative characteristics.

Bounce™ Cherry Impatiens is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use
  • Container Planting
  • Hanging Baskets

Planting & Growing

Bounce™ Cherry Impatiens will grow to be about 20 inches tall at maturity, with a spread of 20 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 18 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. This fast-growing annual will normally live for one full growing season, needing replacement the following year.

This plant does best in partial shade to shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Bounce™ Cherry Impatiens is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. It can be used either as ‘filler’ or as a ‘thriller’ in the ‘spiller-thriller-filler’ container combination, depending on the height and form of the other plants used in the container planting. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
