Q: I have Japanese beetles on my roses and grapes every year. Are there any plant’s they don’t eat?
A: Japanese beetles can make lacework out of grape, rose, hollyhock and plum leaves in just a few days.
You can still have an attractive landscape with entertaining these insect invaders by using plants that are not very attractive.
The USDA has an excellent Plants not Susceptible to Japanese Beetles
One of the things I found curious in it is that among crape myrtles, some are more resistant than others. ‘Acoma’ is not likely to be damaged, while ‘Pecos’ ‘Yuma’ and ‘Natchez’ are common menu items for the beetles.
