No Longer Impatient for Impatiens

By A Glodman

Welcome back old friend!  The ubiquitous annual that all shade gardeners loved is back and ready to create season-long color.  Impatiens are what we are discussing.

Impatiens walleriana were attacked by Impatiens Downy Mildew (IDM). This disease caused defoliation and eventual death of impatiens well before the growing season ended. The disease was difficult to control; and airborne and overwintering soil spores re-infected new plants. This disease essentially ended sales of the once common annual.

Other annuals came to the shade gardener’s rescue; Begonia, Torenia, Coleus, New Guinea impatiens, and Caladiums but some things can never be duplicated. 

Through a collaboration of plant breeders and extensive plant trials in Washington State, Michigan, Colorado, Texas, Minnesota, England, Australia, South Africa and here in Pennsylvania at Penn State, two varieties were deemed to be worthy and will be introduced for sale in 2020. 

Beacon and Imara are the two brand names these new impatiens will be sold under.  The Penn State trials that were overseen by Sinclair Adam revealed Beacon to be slightly better in Pennsylvania gardens.  Both Beacon and Imara are hardy and vigorous for your garden but with any plant, conditions may favor one variety over the other.  Color variety is not as extensive as previously but I am sure with time we will have many more to choose from.

Keep an eye out this spring for the reintroduction of this hardworking, floriferous, easy care annual.
