The Aster Daisy

The word aster means star in Greek.  With their star-like shapes, it’s clear why certain plants in the Asteraceae family are called aster daisies.  The aster genus includes about 170 flowering plant species, but only one of them grows wild in the mountains of North America.

History of the Aster Daisy

Asters appear all over the world, so their exact origin isn’t clear.  While many asters are native species that have been around for a long time, there are also cultivated asters that have been developed.

Goddess Tears

The aster daisy has a prominent place in Greek mythology. The story is that one day the Greek goddess Astraea became very upset over how few stars there were in the dark sky. She began weeping so much that her tears fell to the ground and turned into aster flowers.

In other Greek myths, asters were placed on the altars of gods and came to symbolize love.

A Revolutionary Flower

On October 31, 1918, a vast number of protesters in Budapest wore the flower during the ongoing Hungarian revolution and because of this it became known as the “Aster Revolution.”

Characteristics of The Aster Daisy

The aster daisy can grow to be one to six feet tall. The flowers can be white, yellow, red, pink, purple, lavender, and blue, typically with yellow centers.

Aster daisies are perennials and likely to return the following year so, unlike annuals, they don’t need to be replaced.

Daisies can grow in just about any condition, and they spread rapidly, they’re often thought of as weeds.  But with the right maintenance to control them, there’s no reason they can’t make a lovely addition to your garden.

Bloom time 

Asters bloom in late summer or early fall. However, some species of asters actually bloom beautifully during other times of the year, with one blooming in the wintertime. With asters, your garden could be blooming well into fall.

Medicinal / Culinary Uses

Like young English Daisy leaves, the aster daisy is edible – in this case, the flowers as well as the  leaves can be eaten. You can add them to salads and use them for tea.

Tea made from aster root can be used as an herbal remedy to provide relief for ailments such as allergies, asthma, headaches, and stomach upset.


Floriography (using flowers to send coded meanings) was at its height during the Victorian era and the different colors of asters were used for specific meanings.  Royalty and wisdom were represented by the popular purple aster.  Purity, innocence, and perfection were the messages of white asters.  Devotion was signified by a red aster and a pink aster represented love.

Today the white aster represents new beginnings, while red and pink asters still carry messages of love from the giver to the receiver.

If you have a birthday in September, then asters are your birth month flowers.  For couples celebrating 20th wedding anniversaries, a floral arrangement of asters is the appropriate gift to mark the occasion.

Are Asters Really Daisies?

Asters are daisy-like wildflowers that are in the Asteraceae family of plants that includes daisies, as well as sunflowers, chrysanthemums, and even lettuce.  

The main difference between daisies and asters seem to be the central disk – it’s larger in daisies.  So while asters aren’t botanically the same as daisies, they are closely related.

Growing an Aster Daisy in Your Garden

Aster daisies are very easy to grow if you know the basics.   Seeds sprout in just 10 to 20 days, which means you won’t have to wait long to add them to the garden.

Asters attract beneficial insects, so they’re useful for creating pollinator gardens.  With their bright, colorful flowers growing on long stems, they’re good candidates for cut flower gardens, too.

Where to Plant Them

These colorful plants grow better out in the full, bright sun. 


Like most garden plants, aster daisies grow well in fertile, well-drained loamy soil. Asters can die if they’re in soil that always stays wet.

If they’re in good soil, these plants are hardy enough to potentially survive the winter. They can usually even survive a frost. 

When to Plant

You can plant asters at any time during the growing season. The best planting time, though, is in the spring.

Companion Plants

Asters are beautiful on their own, but you can combine them with other plants for even more effect in the garden.  Some good companion plants for asters include:

  • Mums
  • Coneflowers
  • Goldenrod
  • Black-eyed Susan
  • Cornflower
  • Hydrangea
  • Joe-pye weed
  • Montauk daisy
  • Red valerian
  • Ornamental grasses
  • Zinnia
  • Sunflowers
Yellow sunflowers.

Different Varieties of the Aster Daisy

As mentioned earlier, there are approximately 170 species of asters and they come in a wide range of colors.

The purple aster daisy is probably the most recognizable to a layman and the variety most people think of when they hear “aster.”  Blue and yellow varieties such as are also popular choices for the pop of cheerful color they bring to a garden.
