Sometimes referred to as tidytips or layias, the genus is known for its daisy-like flowers that come in a variety of colors like white, pink, and yellow. In common parlance, the flowers are often referred to as California-daisies, woolly heads, and coast tarweeds. Layias are a popular choice for gardeners and horticulturists alike due to their hardiness and their ability to attract bees and butterflies.
