Purple Dome New England aster is a refined plant for the garden border with its symmetrical, compact mounded form reaching only 2’ tall. In early autumn, it is covered with dense clusters of purple, daisy-like, semi-double flowers. While this aster can have late season foliar problems, it’s dense floral displays and short stature make up for this shortcoming. Purple Dome New England aster grows in sun to filtered shade and performs best in moist, well-drained soil, though it is tolerant of short dry periods.
