Faits intéressants
Purple-stemmed Aster has masses of pale violet to blue flowers and distinctive purple-tinged stems. The purple stems are its signature feature. The stems can become increasingly purple as the growing season progresses, making this a useful identification characteristic.
What looks like a single daisy-like flower is actually a flower head made up of many tiny individual flowers—a characteristic of the sunflower family.
Purple-stemmed Aster can become quite tall creating an airy cloud of flowers above other plants. It is a valuable late-season nectar source when relatively few native plants are still flowering. After flowering, the plant produces seeds with fluffy hairs that allow them to travel in the wind. It can be quite graceful when planted among other tall native plants rather than treated as a solitary specimen. More sun generally produces sturdier stems and more flowers.
