Reported to be grown in England in the 16th century. This plant was first discovered in Syria, but it is native to China.

Author's Notes
Although this plant will have winter kill, I still use this in my garden because of its late flowering. A friend on mine has seedling appearing all over her yard from this plant. (Notes update 2014) I have been in the landscape business for over 35 years. Back in the 1970's and 80's when I used this plant it seemed to be a bit touchy. Currently I have changed my view on these plants and they are much hardier, because of the climate change where I live. We have warmed up at least 1/2 hardiness zone.
