My outdoor plant is about 17 years old but you would never guess as it is
killed to the ground each year and returns in spring, if you have a cold

also keep a number in pots to guarantee flowers.

That's it, I've decided this is to be my next baby. I'll keep her in a
pot - there's always room for pots. I sadly have no ground room anymore.
