I would not say the verdict is unanimous. It is certainly not a thug in m=ay garden, but it is at least marginally hardy here.

I got one at Funkie Gardens a few years back. I like it, but my gardens a=re not known for "neatness."

It could be something that after years of selection for our climate might=become a problem.
