Baeuty of Aster flower ....

Due to the recent narrowing of the Aster genus, identifying asters can be difficult. Every aster species features composite flowers, meaning that the aster has a circular disc flower in the center, as well as several longer ray flowers that radiate out from the disc flower.

The ray flowers are often mistaken for flower petals, but they are actually individual flowers. In general, the disc flower of an aster will be yellow or brown in color, while color of the ray flowers varies greatly from one species to the next.

Asters generally have coarser stems which are often woody near the bottom. The leaves tend to be dark green, and are often long and narrow, much like the ray flowers.

Meaning
A historic tradition of the Dutch is to collect large bouquets of asters and display them in colorful windowsill decorations. French soldiers used them to decorate another environment: the graves of fallen soldiers. The aster was also commonly featured at the feast of St. Michaelmas, as they were one of the only flowers still in bloom when the festival arrived.

For this reason, certain species of the aster are still referred to as Michaelmas flowers. Currently, the aster is the birth flower for the month of September, which makes sense, since asters bloom near the beginning of September. The red aster and blue aster both signify new beginnings, such as the start of the academic year.

Cultivation and Care
Aster flowers should be planted in areas with plenty of exposure to sunshine. They also require well-drained soil and aren't suited to areas that collect large amounts of water. Aster seeds are best planted in mid Spring, while seedlings can be planted in midsummer.

Most asters need regular care, but are hardy enough to do alright if you have to go on vacation for a week or two. The dwarf aster is especially hardy and may be a good choice for those with little gardening experience.

Water asters regularly with a soaker hose. To enhance the growth of the aster plant, feed it water soluble plant food twice each month. If the asters are growing in well-mulched soil, you may not need to use fertilizer at all. Mulching the environment of the aster is also a great way to keep pests away.
Diseases and Pests
The main pest attracted by aster flowers is the aphid. This pesky little insect consumes the aster leaves and can damage the overall health of the flower. Pesticides can be used to keep aphids away, as can releasing ladybugs in your flower garden.
Uses
Asters are commonly seen in bouquets and gardens. Their roots can be used to make a delicious red wine. And the ray flowers are used as a treatment for snakebite in many cultures
