Should I prune my Butterfly Bush back to ground level now?

I accidentally mowed one tiny Butterfly Bush with my lawn and it
produced beautiful flowers.

I am tempted to cut them back to ground level now the weather is
getting cold.

Any advice?

Thanks

Chris

It depends on the species. Some -- including the orange butterfly bush
(Buddleja globosa), the fountain butterfly bush (B. alternifolia), and
the woolly butterfly bush (B. marrubiifolia) -- should be pruned
immediately after flowering. Others -- including the common butterfly
bush (B. davidii), also known as summer lilac -- should be pruned near
the end of winter.

Well you said you accidentally "pruned" it once before, just do that again at the same time of year you did last time!
