We have been selling field grown daylilies and would like to get into other perennials. I'm thinking of ordering some Bluestone "jumbos" which they say can be shifted into quarts for spring sales. I read on a previous thread that a quart pot will hold about 64 cubic inches of soil. I can't find anything that holds that amount. The 6" azalea pot holds 77.9 cubic inches. What size pot do you suggest I get to plant these perennials in?

As is obvious, I am a novice and would welcome advice. Just don't tell me to give up because I can't!
