Here on garden.org, the smallest container size recommended for any variety of abutilon is 3 gallons. This surprised me a bit, given that fuchsia are labeled for 1 gallon.
What do you think is a reasonable minimum pot size dwarf abutilon with a mature size of 12"-12"? What about a container with a dwarf abutilon and a fuchsia? Is that a doable plant combo for a large hanging basket?
