I am interested in these dwarf lilacs. I was thinking of using them in containers on my deck which gets full afternoon sun. Are they able to winter over in pots? I have had some success with potted perennials by wrapping the pots in newspaper and putting them in a secluded spot. Can you give me any advice here?

Depending on the variety, dwarf lilacs planted in the ground are winter hardy down to zone 3 or 4. However, as you've mentioned, plants in pots are more exposed and sensitive to cold weather and will need protection. I think you could overwinter them in pots by wrapping them up (especially the pots) with multiple layers of newspaper, burlap, or other materials, with perhaps a layer of thicker material around the outside, and/or moving them into a garage or a spot protected from the wind. Here are some other techniques you could try:
