Hello I just got this beautiful miniature called Rainbow Sunblaze on sale at Lowe's. I want to keep it in a pot if possible, it's currently in the one gallon they sell them in. What size would I need for potting it up? Can it be kept in a hanging basket at all or would that be too small, even for now? I'm willing to get it a big pot if needed. I'd like to avoid planting it in the yard as the soil is poor and we're planning to move within a year or two hopefully.

Mary
