I have grown agastache, but not always successfully. One year they were Apricot Sprite that I grew from small bought plants, they were super. Then I tried a purpley one but it didn't thrive. I've tried sowing them but they didn't germinate. This year I have a pink one called Heather Queen bought as plug plants. They are still tiny, have only just started growing and I planted them out in May. They rarely last the winter here. What am I doing wrong?
