Potentilla 'Happy Face Yellow' is a low-growing deciduous shrub with a mounding habit. It typically reaches a height of about 1 to 2 feet (30 to 60 centimeters) and spreads about 2 to 3 feet (60 to 90 centimeters) wide. The foliage consists of small, dark green leaves that are divided into several leaflets, giving it a fine texture. During the spring and summer months, it produces an abundance of cheerful, buttercup-yellow flowers with a diameter of about 1 inch (2.5 centimeters). These flowers have five petals and a bright center, adding a vibrant splash of color to the garden.
