Prob right Chicky but taking cuttings in mid to late spring and then to overwinter in a gh in colder places. I grow the more tender varieties 8000 Wildflowers but if you give them sharp drainage, warm soil and not too cold for too long in winter should produce survivors. they all survived outside this year.
Sorry, I can't stop gushing when talking about agastaches.
Bowles Mauve will exhaust itself eventually therefore, again, cuttings every year
