The Symphyotrichum dumosum is a genus from the aster or sunflower family (Asteraceae or Compositae) and is native to the eastern half of North America.
The Symphyotrichum dumosum 'Professor Anton Kippenberg' is also called Symphyotrichum novi belgii 'Professor Anton Kippenberg'. The bushy aster used to be called aster dumosus but after a phylogenetic analysis the name was changed. Dumosum means bushy.
The more sun the bushy aster receives the more flowers it produces. With too much shade the Symphyotrichum dumosum 'Professor Anton Kippenberg' will hardly produce any flowers at all. The bushy aster is salt tolerant and hardy.
The bushy aster does not grow very high and grows compact (bushy). The stems stay upright and do not need support. The Symphyotrichum dumosum 'Professor Anton Kippenberg' spreads with rhizomes. To keep it in place you might want to put a plastic rim around it.
The bushy aster newly emerges every year. In spring you can cut away the old and dead stems to make room for the new stems. The bushy aster is very suitable as cut flowers and they attract butterflies.
