One will be more than sufficient. I'd plant it nearer to the door to the right and train it to go in both directions. I don't think the man at the garden center has ever grown ND. tneeds sturdy support and good air circulation. I've put two post supports in the dirt with treated wood as tall as I need and run wire between them, but sturdy wire fencing would also suffice. However, I do feel there may be other better climbers for your situation, so near an entrance and walkway as she is a vigorous thorny grower. Maybe Cl. Cecile Brunner? I hope other more experienced people will chime in for suggestions. I have 5 New Dawns, so am mainly familiar with her.

I have a ND on its second year and it hasn't been a monster at all. It is more vigorous than most roses I have but then again I live in a colder zone. It will be beautiful against the beige backdrop but because ND is a softer coloured rose, it will not pop out too much. It will be harmonious nevertheless, tranquil and elegant.

Another idea for your area might be something like a neighbor of mine has. It's a beautiful hanging decoration that enhances a bare side of their house. Then you could do shorter floribundas or hybrid teas in the planting area. Just an idea since the planting space is narrow.

Vaporvac, I totally agree with everything you said about New Dawn. One rose should do it in zone 6 or warmer. But as vapor says, maybe you should try something that's less of a thorny monster (I've grown a few NDs myself, and never want to do it again). Diane

I would have thought that you'd want more color there since New Dawn is pretty much a white bloom

I know this is a question about roses, but when I looked at your picture, your garden bed size & saw your comment about sun to shade the first plant that came to mind for your situation was a climbing hydrangea. They will attached themselves to your wall. Really nice glossy foliage & beautiful flowers. Vary shade tolerant but flowers better with sun. They do take a bit to get going. So I would recommend buying a larger size to start. As for roses you could do a large one like new dawn or perhaps 3 different shorter/smaller climbers that compliment each other colour wise. I could give you examples if I knew what your favourite colours were.

ND will overwhelm that space in NJ. It is also light pink, and blooms well in the spring, sparsely the rest of the year. And, yes, very thorny. It eats most trellises.

The logistics of growing a climbing rose in that space are pretty daunting. It is narrow enough that whatever grows there has to be close to flat, and climbing roses aren't flat. They can be somewhat restrained by a lot of pruning and training, and pulling them up against a trellis. However, to do that, the trellis has to be very solid. My guess is that ND would just pull the siding off the house if you tried training.

I like the idea of some sort of artwork, if you really can't stand the wall. Clematis is another idea.

Climbing hydrangea is beautiful, albeit slow-growing and vigorous once it gets going. It attaches directly to the siding with it's suckers which means no trellising if desired, but that also means it trashes out your siding. Pyracantha can be espaliered to grow flat and you might also consider a climbing vine such as hardy kiwi. If you plant male and female, the fruit are delicious. I would try to espalier something, maybe even a fruit tree if the soil is good and there's space for a big enough hole.

However, if your heart is set on a rose, I'm sure there are some that would suit your needs. Hopefully, someone with chime in with a suggestion. BTW, how deep is that bed?

I say go for it, to me it sounds like you really want New Dawn. Rose growing is all about trial & error, also what maintenance you are willing to provide. I removed 2 ND after 3 years, they were at an entrance to the pergola & too thorny & lusty for the spot but YOU must try to do what your heart seems to want.
