It produces small, white flower clusters that have four petals, which are deeply lobed. The plant has a rosette stage with leaves that get progressively bigger and have light-colored mid ribs. The stems and leaves of the hoary alyssum are very narrow and are covered with short, white hairs. The seeds are fairly large, oval-shaped, and laterally flattened. It is considered toxic to horses causing a number of different symptoms.
