I got Agastache Heat Wave at Lowe's two years ago. It did not survive this spring. I keep going to Lowe's once a week to see if they get any this year. So far none. They only had an agastache in a planter with other "undesirable stuff" . But I keep going back.
My mom got a whole bunch of agastache from her local Lowe's down in Georgia. Still none were Heat Wave
