What is Hoary Alyssum?
Hoary alyssum is botanically known as Berteroa incana. It is an annual, biennial, or perennial herbaceous plant of the mustard family that grows one to three feet tall.
It has upright, branching, gray-green downy stems with several branches at the top. Hoary alyssum has tiny, lance-shaped leaves that are coated in a grayish-green hairy down and have smooth leaf margins.
This plant produces small white blooms that grow in long clusters along a central stalk. Each flower has four deeply split petals that combine to form a long raceme. These flowers are normally in bloom from June through August.
Hoary alyssum favors dry, disturbed areas like roadside ditches, rail embankments, and rangelands. Hoary alyssum spreads rapidly throughout its extended seeding season. Vehicles, equipment, footwear, animals, and birds all spread seeds.
Keeping Cats Away From Hoary Alyssum
You can prevent cats from touching your hoary alyssum and other houseplants by using natural deterrents. You can get this online or from any pet supply store near you.
Placing houseplants in a room inaccessible to your cats is also a good way to prevent them from touching (or messing with) your plants. Cats are less likely to reach a plant that is not in its usual placement.
You can also try other hacks such as placing aluminum foil on the ground near your plants. You can also try wrapping your plant pots with double-sided adhesive tape. Cats who love to scratch your pots will avoid this now because they detest the sticky texture of adhesives.
