It was thought that there were more than six hundred members of this species; however, research in the late 20th Century found that many of these species belonged to different genera. Now there are thought to be 180 species in this genus.

Where Does The Aster Plant Originate?

True Asters originated in Asia and Europe. Those native to the Americas are among those that have been reclassified. These plants are still referred to by the common names Aster and Daisy. Asters are also commonly called Michaelmas Daisy in Europe because they bloom very late in the season. 

Where And How Are Aster Plants Used? 

Late in the summer and early autumn, Asters and those with the common name Aster bloom widely. For this reason, these plants make an excellent, colorful late-season addition to any flowerbed or landscape.

The plants produce masses of flowers in shades of: 

  • Purple
  • White
  • Blue
  • Pink

The blooms are beautiful to butterflies, bees, and other winged pollinators. They make an excellent, late-season food source for these beneficial insects, so they are a perfect choice to round out your butterfly and pollinator garden.

Other good uses for Asters in the garden include: 

  • Wildflower Gardens
  • Prairie Planting
  • Rock Gardens
  • Naturalizing
  • Borders

Your use of these plants depends significantly upon the type you choose. Asters can range in height from eight inches to eight feet. 

Some varieties spread as ground covers. Others stand tall on sturdy stems. Some bloom briefly, while others may bloom throughout the late summer and autumn. 

Tall, sturdy, long-blooming varieties make good additions to your cut flower garden. 

Varieties Of Asters With Descriptions

The 180 species of Asters that remain classified within the plant family, Asteraceae, are divided into New York Asters (Aster novi-belgii – no’ vee bel’ gee) and New England Asters (Aster novae-angliae -no’ va an’ glee’).

Aster Terminology

  • Alpine Asters (alpinus – al-pie’ nuss) do best in the northern and western plains of North America. 
  • Italian Asters are the amellus (a-mell’ us) Asters discussed above. These plants have furry leaves and stems and are usually created by crossing frikartii with another type of Aster. 
  • Climbing Aster is also called carolinianus (cair-o-lin-ee-aa’ nuss). This terminology is applied to those Asters with long, flexible stems that droop and arch. The plants do not climb. 

Which Aster Is Right For You? 

There are many different types of Asters, and we have just scratched the surface with those we have presented here. 

It’s important to understand that most Asters are hardy perennials. They fall under a wide variety of classifications, and they come in a wide range of heights, spreads, colors, and bloom times. 

Most Asters bloom in the late summertime and autumn; however, quite a few New England Asters bloom mid-summer. 

New England Asters typically have longer-lasting blooms, so they are better for a cut flower garden. Their colors are usually held more aloft than the New York variety, so they make a more conspicuous showing in your garden, and they are more attractive to pollinators. 

New England Asters tend to come in bright red shades, while it can more often find it in the New York Asters in various shades of blue, purple, and violet. The New York cultivars usually have darker green foliage than other types of Asters. 

It is also important to note that New England Asters are wildflowers. They are great for naturalizing, but they may be more subject to rust in a garden bed environment. 

Both New York and New England Asters are very easy to grow, so a combination of the two could give you a lot of variety in your garden with effortless care.
