Mountain alyssum is a short perennial flower grown for its bright yellow flowers.
It has grey-green leaves which form a low-growing mat. In spring, the plant is topped by clusters of tiny fragrant yellow flowers.
It works well in rock gardens and areas where a small, mat-like plant are desirable. Can also cascade over the edge of a wall or boulder.
Mountain alyssum is sometimes confused with basket of gold. Basket of gold is a larger plant and more commonly planted.
Mountain alyssum has been winter hardy and a reliable bloomer at the Xeriscape Garden. It is rather small, so it needs to be sited in an area where it will be noticed.
Prune off spent flowers, if desired.
