What is Frost aster
Frost aster (scientific name: Symphyotrichum pilosum, synonym:Aster pilosusAster pilosus) is a perennial naturalized plant of the genus Zionaceae, native to North America. It is also called peacock (peacock grass) or aster (Aster). The lower stalk becomes woody and grows to 120 cm. The petals are initially white but turn red-purple over time. Since the branches often diverge, it hangs down and you can see that they are tied together with a string. The aster is a single flower, but there is also an improved double flowering variety.
