Growing and Maintenance Tips:


Aster puniceus, commonly known as Swamp Aster, grows best in full to partial sun, in wet to moist conditions. Soil should consist of plenty of organic material to hold moisture. Drought conditions will cause this aster to go into early dormancy. Plant height and width vary depending on location and soil moisture. Naturally found in highly fertile, low-lying areas, along streams and ponds.
