Daisies belong to the Asteraceae family, an enormous family of flowering plants that also includes sunflowers and asters. Daisies are common sights throughout the world, popping up with little effort in lawns, roadsides and cultivated gardens. The cheerful, disc-shaped flowers of dozens of species of daisies are cherished as easy-to-grow ornamental flowers.
Shasta daisies (Leucanthemum) are perennial flowering plants that grow in a range of well-drained soils. Popular for their blooms and their ability to attract butterflies, the Shasta daisy is a hardy flower that loves full sun. Varieties include the "Summer Snowball" (Leucanthemum superbum 'Summer Snowball'), a plant that produces fluffy white flowers in mid-summer until mid-autumn, and the classic-looking Alaska Shasta daisy (Leucanthemum superbum 'Alaska'), a re-blooming daisy that produces flowers throughout the summer and early fall.
The common daisy (Bellis perennis), also referred to as "Lawn Daisy" or "English Daisy," is a widespread plant that grows freely throughout North and South America, as well as Northern, Central and Western Europe. Though many gardeners value the appearance of the common daisy on lawns, the hardy plant (which can't be removed by lawn-mowing alone) is considered a weed. The small herbaceous perennial is perhaps best known as the flower commonly used by children to make daisy chains.
The Gerber genus (Gerbera) contains approximately 30 species of plants. Native to Africa, South America and parts of tropical Asia, the Gerber daisy is a widespread and commonly recognized flower. Species produce flowers in a variety of colors, from brilliant orange, to yellow and pink. They are popular commercial flowers, frequently making their way into supermarkets and nurseries in time for Easter. Gerber daisies grow well both indoors and outdoors in well-drained soil and indirect sunlight.
