Alyssum may refer to Lobularia maritima, sweet alison, or sweet alyssum in the genus Lobularia or any of the 100-170 flowering plants in genus Alyssum. Initially, Lobularia maritima was classified under the genus Alyssum, hence the name. Both are in the Brassicaceae family, otherwise known as the cabbage, mustard, or crucifer family.
Rabbits don’t eat alyssum flowers or foliage (leaves, petals, or stems). While you may eat the sweet alyssum petals, tender stems and leaves (raw or cooked), and some alyssum foliage may serve as food for Gem (Orthonama obstipata) and other caterpillars in the order Lepiodeptera, rabbits hate them and will not eat them, i.e., they are one of the bunny resistant plants.
Therefore, if you are growing them for your consumption or as a ground cover, being one of the heat and drought-resistant plants, be assured that wild or bunnies will not bother than at all.
However, when there is scarcity, it is possible for your bunnies to nibble some of your sweet alyssums but won’t cause much damage since they are plants they would usually avoid.
