I love this little plant. It is non invasive, but seeds itself moderately, one or two plants a year. It is very hardy here in Massachusetts. It is a pretty plant with nice green leaves, around 8" high.Behaves itself. Green all summer. I also have, probably, an acid soil or thereabouts, and I never water it.Love it
