Cineraria blue daisy (Pericallis X hybrida) is a bold colored perennial in the aster family. Hardy in USDA zones 9 through 11, the plant is grown as an annual or houseplant north of those zones. The mounding green foliage covers itself with solid or bicolor blooms in winter and spring. Blue daisy plants also are called cineraria, common ragwort, or florist's cineraria. 

Blue Daisy Flowers

Many of the daisy like hybrids feature vivid colors with a contrasting eye. Once only bright colors such as blue and purple were available, but now multiple colors are offered. They are easy to propagate from seed or cuttings. 

A favorite in the floral trade, blue daisy plants are forced to bloom in winter and early spring. Blue daisy flowers are often given as gifts that bloom through the winter. They can be hard to rebloom, so blue daisy plants are often discarded after the flowers fade. However, with the right care, they can move outdoors in spring and continue to bloom in cool but frost-free weather.
