This herbaceous perennial grows up to 100 cm tall. The flower heads are born in paniculiform arrays. The ray florets are blue, pink, purple or white, while the disc florets are pale yellow, turning pink with age.
Asters like moist soil. They can tolerate lower levels of soil moisture as long as it’s not completely dry to the touch. Water your plants well during stretches with no rainfall.
Asters need a spot with full sun to grow and bloom their best. That means their growing site should get at least six hours of sunlight on most days.
Plan to fertilize your asters in the spring when new growth appears. Use a water-soluble or granular fertilizer made for flowering plants.
These plants prefer rich soil with a slightly acidic soil pH and good drainage, but they can grow in other soil types as well. They’re even tolerant of clay soil.
If you are planting seeds, they should germinate with a soil temperature of 65 to 75 degrees Fahrenheit. Extremely hot weather can make the plants wilt, but they should come back fine once the temperature cools.
