Recs for tall but narrow accent shurbs?
I am looking for a tall and narrow shrub to place on either side of the steps leading up to the front door of the house. We had hired a landscape designer and she put plum yews (fastigiata) in the plan. I think they are nice, but I am bothered by their slow growth (do they really just grow 3-4 inches a year?), and the largest I can find locally are just 2 feet tall.
I am considering:
sky pencil holly
green spire euonymous
Any thoughts on these and any other suggestions?
Some additional info:
other foundation plants will be indian hawthorn (3-4 ft tall). Exposure is east/southeast, so it gets a good 6 hours of sun and some late afternoon shade. One side of the steps is constrained by the steps, foundation, sidewalk and driveway, so the space is 4x6 feet. So I obviously may have to do some pruning.
I am considering conifers, too, so I also posted a similar question in the conifers forum.
