Aster plants get their name from the Latin word for "star;" take one look at these cheerful flowers and it's no surprise why. For one, their shape is akin to that of a star or sunburst. They also come in eye-catching bright colors, such as white, pink, and a unique shade of purple. The majority of aster plants are known for blooming in fall and bringing their signature brightness to autumnal gardens. However, some asters bloom in spring or summer.
