It grows at a fast rate, and under ideal conditions can be expected to live for approximately 5 years.
This plant should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under typical garden conditions. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider covering it with a thick layer of mulch in winter to protect it in exposed locations or colder microclimates. This species is native to parts of North America. It can be propagated by division.
