I regard the Buzz varieties as needing better soil and comditions than the usual buddleias.
Conflicting opinions above but I don't think buzz is good in pots for more than one season.
I have buzz Ivory purchased earlier this year. It's about 5' tall and full of flower. Been flowering for few weeks. It's in a dryish spot but has good soil. Not fed. I deadhead as soon as flowers go over which prolongs flowering
