My Agastache Blue Boa looks like a handful of dead sticks. Thanks to Verdun,, I bought Blue Boa and Black Adder last autumn. As I have never kept an Agastache in the flower borders through winter, I potted them on and put both in a cold frame. Black Adder never lost all it's leaves, which are rather pale green now, but it is making new darker heart shaped leaves with serrated edges. Blue Boa has died down completely and I'm wondering if, or when, it will show.
