Are Impatiens Now Resistant To Impatiens Downy Mildew

Question From: Troy, Michigan, United States
Q: For 1st time in years in Michigan, I saw flats of impatiens (at a Meijer in Troy). Are they now resistant to that wilt or whatever got them years ago?

A: Chet, they are not resistant to impatiens downy mildew, garden centers are just bringing them in because customers want them. Who knows what will happen? Many garden centers will not guarantee them. It's a crap shoot. I choose not to grow them. Best And Happy Yardening, Nancy
