Is the Japanese ‘Crimson Queen’ laceleaf maple deer resistant?
I found Japanese maple (Acer palmatum) on a few lists of deer resistant plants. (One source is Pacific Horticulture, v. 47 (3) 1986, “Co-Existing with Deer,” by Mary Lynn Cox)
None of the lists mention specific cultivars, such as your ‘Crimson Queen.’ But the risk of damage should be lower than other plants that deer prefer. Every article I read warned that a starving deer will eat anything, so no plant is 100% safe.
