Suggestion please?? Need a specimen shrub

I have a 4 ' x 4' piece of ground next to where my driveway meets the street and would

to plant an evergreen shrub which is dense but will look nice when trimmed to be in that

space. Can be about 4 ' high.

I was thinking about the type of evergreen that has needles and seemed to be easily

trimmed... seen a lot of them in yards but don't know the name or which varieties are

the best ones to get.

Are there any other choices that one would use ?? I already have hollies, roses, yews

and other classical plants in adjacent beds, but would like this to be a nice..."knock

your socks off" entryway into the garden.

Located in zone 7.... location gets full sun, temp's range from -10 to

get some decent rainfall over here in sunny maryland, but also a couple of years of

drought every now and then.

Thanks in advance for your suggestions !!!

Peter
