You can propagate them from hard or soft wood cuttings.
Hardwood cuttings are made when the plant is not growing much - usually late autumn or spring. Cut off a woody stem near the base, then cut again just under a leaf node (one of the bumps where the old leaves were). Remove the growing tip so you are left with a cutting about 12 inches long. Leave only a couple of leaves up the top and strip the rest . Plant in potting mix or sand. Water and wait until new growth is established until planting it out.
Softwood cuttings are taken in summer or autumn. Use the top new growth with about 2-4 sets of leaves. Again, trim under the lower set of leaves and remove all except the top ones, plant and water. These softwood cuttings are more susceptible to drying out, and need to be kept moist and possibly enclosed with plastic to keep the humidity up.
If this all sounds very complicated, don't worry! Many plants will root fine if cut off as described and put in the ground. The above methods, though, will increase the success rate.
The Butterfly bush is Buddleia.
No. No.
I live on the coast of British Columbia and I prune the butterfly bush in early spring, by cutting it back to about 18" from the ground and it grows approximately five feet every year and blooms vigorously.
Buddleia is the scientific name for butterfly bushes.

The Butterfly Bush or Buddliea does not have to be pruned for repeat flowering but to keep it compact and tidy you can prune it as hard as you like in early spring.
No. The butterfly bush flowers, but only in the right conditions (obviously). It also depends on the type of bush.
yes you can
Summer lilac is another name for butterfly bush. The flowering plant in question (Buddleia spp) makes some gardeners think of lilac in terms of bloom colors, fragrances and shapes. Butterfly bush prevails as the more common, popular and widespread name because of attracting butterflies.
