Growing Rhubarb

02 May 21 Trish I. (USA - Zone 7b climate): We have very recently (April) moved some rhubarb plants that originated from my FIL's family homestead many years ago, from Denver CO to SC. I desperately want to keep these alive, mostly for my husband. Any advice? Our ground is hard as a rock in most spots and has a lot of clay, so figured I need to keep them in pots. How big of a pot do I need, should I be sure to put them on the side of the house where there's mostly only morning sun, in order to continue the "family line", should I try and gather seeds from the plant for the following year? Thanks!

Rhubarb get very large and can live for many years and their root systems can get quite large, keeping them in pots will restrict their growth and you will have to water more often and continually use fertilizer more often then them being in the ground.
