Mountain Alyssum

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.
