Overwintering
Amber Jubilee Ninebark does not require much winter care.
As a perennial deciduous shrub, many cultivars of ninebark lose their leaves and enter dormancy during the winter.
It does suffer from a few common diseases, but these are not too troubling and are easily controlled.

This cultivar along with all ninebarks is extremely long-lived.
They can easily live up to 100 years.
All ninebarks grow relatively fast.
They grow around 15 inches per year, but this depends on the conditions they are grown.
The ninebark gets its name from what many consider its most attractive feature, its peeling bark.
