A rabbit (I think) ate the blooms of my impatiens. They did not dig up the roots. Will the blooms (flowers) come back or not? Thanks so much for the info.
I would venture to guess that either slugs or cutworms are the culprit in question. Neem oil may help with cutworms, as well as most other insect pests. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/facts-about-slugs-and-how-to-kill-garden-slugs.htm
