Dude! These are the best to bring in the pollinators and they're so goddamn beautiful. Once I picked one from the stalk, just to see if I good 'live stake' it. It works! I planted one orange one and I ended up with them everywhere in all different colors. (I wish I knew how to turn the picture around!)
They reseed like nuts, too. We have a bunch coming back from where we threw the dead heads last year.
I got these hot pink ones grow in my garden that didn't grow anywhere else on the property. I wonder what causes certain colors...
