China Aster (Callistephus Chinensis Sea Star) - Start Aster seeds and grow many of these showy annuals for the flower beds or garden! China Asters are good as cut flowers in bouquets, beds, borders or pots because of their longevity. Visitors will do a double take when they pass these lovely and unusual Callistephus Chinensis, or China Asters, in the garden or the vase. Big 3 1/2 to 4-inch blooms are full of brightly-colored, needle-shaped petals that are arranged in swirls atop tall, sturdy stems. These blooms are dense, deeply colored, and long-lasting. Best of all, they appear profusely on very vigorous, uniform plants.
This Sea Star mix contains 5 complementary colors: white, pink, deep rose, and purple. These large-flowered China Asters make a spectacular bouquet all by themselves, and their unusual form combines well with other flowers in the bed, border, or vase.
Callistephus Chinensis is also known as Crego Aster and is quite wilt-tolerant and undemanding, asking only for a sunny spot in the garden. Crego Aster seeds can be direct-sown outside after the last frost or, for even earlier blooms, begin flower seed indoors. Sow China Aster flower seed indoors in early spring using starter mix. Press flower seed into soil and barely cover. Transplant into the garden 20 inches apart.

Aster plants are not picky about soil types, but they do require full sun to partial shade to do their best. It is recommended to grow Aster flowers in a different location each summer to avoid disease.
To get a jump start on the growing season, start the Aster seeds indoors 6 - 8 weeks before the last frost is expected. For areas with long growing season, Aster seeds can also be started directly outdoors in prepared seedbeds. Make sure that frost danger has passed before either directly sowing flower seed or transplanting Aster plants started indoors. Press the flower seeds gently into the soil and lightly cover.
