@Miamiu Eric,
Usually the Kroger's and Meijer's close to my home has just the regular and ordinary type of plants, but once in awhile, I spot a great find. That's why I have to order online.
I haven't grown Tutti Frutti for a lot of years. I always planted it in the ground, but this year, I'm going to pot it up into a container. I haven't decided what size yet. Either a 16 inch, 20 inch or a round tub (those tubs in stores that have white ropes for handles). I don't know about a 3 gallon tub, as I don't own one.
Bluestone Perennials in OH has their Agastaches (as well as other plants) on sale.
