| If I had lean fast-draining soil I would plant every Agastache on the planet. Alas, we have rich clay. I have grown 'Blue Fortune' with success (it re-seeds everywhere).
I'm wondering if anyone has grown A. cana and A. rupestris varieties in clay soil with any success for more than a few years. Here in southern California, most of our rain is in winter and our perennials live over (and continue blooming) during the winter months. I'm interested in long-term success, not just one or two seasons. I've read about planting on a mound, adding gravel to the soil, not cutting back too soon. What about pots? Could I create the sandy/gravelly/lean conditions in a large pot with any long-term success? |

| Agastache will do fine in pots. I've grown various types in 12 inch pots on my deck. I just use regular potting soil. |

| Thank you. Where do you live? How long is your growing season? Here, many perennials will grow into monsters that are 3-4 times the size of the same plant in a shorter growing season. Keeping them going year after year in 12" pots may be a challenge, but I'm willing to experiment with one or two and see how they do, but in larger pots. |

| I'm in zone 6, have clay soil and love agastaches. I grow Honey Bee Blue and they have come back every year and reseed gently in my garden. I do love the Western Agastaches though, which are more difficult to keep here. Last year I grew two new hybrids from High Country. I was SO hoping they would come back this year. I had two, 'Ava' and 'Orange Flare'. No sign of Orange Flare, but I have a nice cluster of leaves where the 'Ava' was growing. Very happy about that! We had about 5 feet of snow covering that bed just about the entire winter, no exaggeration. I thought that was terrible conditions for the Agastaches. I did prepare the planting hole of both plants according to directions given by High Country, which I believe included adding gravel and sand to the planting hole. I'm going to try more this year. |
