camelia hedge... one variety or mix it up?
I have been working on a landscape plan for our newly built home and would love some advice from you all regarding a camellia hedge. I would like a nice evergreen hedge along the side of our house (partial to full sun) and was originally thinking of just using a row of needlepoint hollies. This morning at the nursery, the owner highly recommended that I change it to a row of camellias. He has many varieties on site and I thought they were beautiful so I am definitely considering using them. My question is this: should I mix the varieties in the hedge to get different flowers and different bloom times or should I just go with one that I like the best (like Taylor's Perfection) along the whole row. The nursery owner thinks I will like the variety of colors and bloom times, but I really want the hedge to have a clean, uniform look to the hedge (same height, width, color of green, etc). What do you all think?
By the way, the wall I would be putting them along is about 27 feet in length, the brick is a light color, and there are only a few small windows on the first floor which are about 8 feet above the ground so the hedge won't block any windows. This side of the house is very visible from the street so I would be nice to have some pretty flowers there. We live in the piedmont region of NC, zone 7. Thank you for any input or advice you might give!
