Morning Glories: How big to Convolvulus get?, 1 by Seamus_tt

I planted a couple of Convolvulus seeds a while ago, wanting to see how these "bush morning glories" would grow.
Online accounts of their growth habits largely contradicted each other - some said that they spread a lot, others that they just sat there and never filled in - so I guessed at a pot size, and gave them 6-inch diameter homes.

Mine have been doing pretty well under the lights, and I'm wondering if this was the right size pot for these little plants. About how much room do these things usually want, and can I expect them to keep spreading, or will they eventually "top out" in size?
