Buddleia Advice wanted please
 

The really annoying thing is, I see buddleia growing wild and
completely untended that has thicker, denser blooms than mine!

I work at a Railway depot which has hundreds of these plants growing wild, I
rather like them. Is it possible to dig up a small one or take a cutting
from a larger specimen and plant it in my garden. If so when is the best
time of year to do this?
