I've got a pretty row of winterberry lining the driveway. But there is a gap.

One of my shrubs has some shoots, a foot away from the main plant. I'd like to dig one up and replant it to fill the gap.

Two questions - will this work? It's a female plant - will it flower and produce berries? (I suppose I will cut the strongest shoot from the root of the main plant, then transplant it)

And what time of year shall I choose?

As a backup, in June I will take some softwood cuttings.
