I do not collect a series all it has to be is a plant that I do not have.
I use to run out of places to plant then I brought a bigger property now I run I do not run out of land I run out of money. Cannot win.
I agree with the "Sold as Perennial Annual". I am there with Heucheras. I love them because I love foliage more than flowers but they just do not like to live for me.
