Late season asters are transitional flowers that bloom between summer and autumn and give the gardens a lot of small flowers and rich texture at the end of the season.

In this article, we focus on 13 companion plants that share cultural requirements and stature with late season varieties.

Let's start with some aster basics and then meet our new friends.

Late season asters are perennials that are generally suitable for gardens in USDA hardiness zones 3 to 8.

They thrive in full sun with organically rich soil that is slightly acidic and drains well. The water requirement is moderate and plants usually have an above-average drought tolerance as soon as they are found.

Stokes & # 39; Aster.

There are native and non-native species. The heights vary from one to four feet or more and it's not uncommon for locals like the New England Aster, Symphyotrichum novae-angliae to top six feet.

Plants have a shrubby, often unruly growth habit and produce a lot of small, daisy-like flowers. They consist of blue, pink, purple or white rays that surround a central disc and can age yellow or yellow and age to reddish purple.

Flowering begins in mid to late summer and often lasts until the first frost.

Some notable types are those Calico AsterS. lateriflorum, New York, S. novi-belgii, Sky blueS. oolentangiense, Tatar, Aster tataricus and Stokes ”(Stokesia laevis).

Companion plants for asters have similar growing conditions and water needs and colors and dimensions that complement each other.
