Asters are a very beautiful part of garden flowers. They are daisy-like, yellow-centered and dainty flowers. Aster flowers love to bloom during fall when other flowers bid goodbye and shed their petals. They bloom in a rainbow of colors like pink, hot pink, white, red, lavender, purple, dark purple with shades, dark red, blue, etc. Aster flowers are easy to grow in average soil but they require the full sun. Mostly Aster plants are perennial while few of them are biennials or annuals. These flowers are the most loved flowers of all people around the world during winters and fall. Being a part of the sunflower family, they resemble daisies a lot as they have yellow centers and ray-like petals.
