The foliage has oval, medium green leaves with toothed edges.

The blossoms may be individual daisy-like flowers, double flower heads or even festive, shaggy pom-poms.

Blossoms 3″ to 5″ inches in size and appear throughout the growing season from early summer until the autumn. Butterflies find China Asters very attractive.

Light & Temperature

Grow China Aster in full sun, but can also do quite well in part shade. These plants flourish in USDA hardiness zones 2 to 11. They are somewhat sensitive to heat and may suffer in USDA zones higher than 9.

Watering & Feeding

Water deeply, occasionally. Don’t allow the soil to dry out completely.

Soil & Transplanting

A cool weather annual, plant China Aster in any well-drained, evenly moist, rich soil. The plant does best in chalky, loamy soil and can tolerate a wide variety of pH levels ranging from acidic to alkaline.

Keep the soil moist, but make sure to plant in well-drained soil.

Grooming & Maintenance

Deadhead flowers throughout the growing season to encourage more blooms. Keep weaker plants thinned to ensure good air circulation.

How To Propagate Aster Callistephus Chinensis

It is best to sow seed indoors approximately two months before the predicted date of the last frost. Set young seedlings out immediately following the last frost.

You may also sow the seed directly into the soil immediately following the last frost.

It’s a good idea to sow seed every couple of weeks throughout the growing season to ensure constant blossoms.

China Aster Flower Pest or Disease Problems

These non-toxic plants may be subject to infestation by spider mites, aphids and leafhoppers. Examine them frequently and spray as needed for these pests.

Disease problems include Aster Wilt, stem rot and Aster yellows.

Aster yellows is a systemic, chronic plant disease caused by phytoplasma in the soil. The phytoplasma causes disease in most members of the Aster family.

To prevent disease, avoid crowding your plants. Plants should be spaced 12″ to 18″ inches apart.

Provide good air circulation and rotate crops from one location to another year-to-year to prevent uptake of disease from the soil.

If you notice diseased plants, dig them up and destroy them.

Is the plant considered invasive?

China Aster has been introduced and has naturalized in several far northeastern states in the US, but is not considered invasive at this time.
