I was wondering if all butterfly bushes bloom on new growth?The reason I ask is because we have had one for many years, we had problem of keeping it upright.We would it back every fall and in the spring it would grow from the root but only on the outer ring of the roots resulting I in the Bush flopping down like the peel of a banana so we had to support it all the way around the outside. We were advised my a local nursery not to cut it back in the fall but wait till spring when we saw new growth which seems to be on the older branches as well as new growth from the roots.So is it possible that some varieties bloom on last season's growth as well. Since we stopped trimming in the fall we have more blooms although we still have to support it.
