    Hello,

    I was given some seeds for the physostegia, and was wondering how invasive (or not) it is in the Lower Mainland area?

    I also want to thank everyone who has answered my questions, this is a fantastic resource.


    Thanks, Trish

    Does not invade wildlands but does spread sideways beneath the ground, close to the previous stems.
