Swooping in to hog the garden spotlight just when other flowers are beginning to fade, aster flowers are the ‘star’ of zone 3-9 landscapes in late summer to early fall. With thousands of cultivars and hybrids derived from more than 200 species, these cheerful perennials are diverse in size and color. They even come in true blue varieties, the most elusive of all flower hues.
Ranging in height from 6 inches to 6 feet with a spread of 1 to 3 feet, asters grow on multi-stemmed bases and feature daisy-like rays extending from yellow-orange centers. The varieties we see most often in the landscape are sorted into New York or New England subspecies. It can be quite difficult to distinguish between the two, but both types are easy to grow.
With so many varieties to choose from, there’s certainly an aster variety for every sunny spot in the garden. Read on to explore some popular cultivars in the New York and New England categories as well as a few other, more obscure flowers. We’ll look at key characteristics from each to help you find an aster or two that you may want to try at home!

Final Thoughts
When planning a garden to include four season interest, asters are a go-to for late season charm and minimal maintenance. With a broad color spectrum and a prolific blooming habit, asters pack a punch in the garden just when it’s needed most.
When selecting a variety to try in beds or containers, pay attention to mature height and stem strength. If a more compact shape is desired, pinch the tops off in mid summer to encourage side branching. When a taller, specimen plant is desired for back or middle borders, let them go but provide support when they get leggy.
Take some time to get to know this reliable perennial and choose a variety that suits your particular garden needs. You’ll be glad you did.
