Can you add photos (even with snow is OK) that show what is to the right and left of these photos? We can’t see how large the yard is or what is around the house.

The two largest needs I see are something tall on either side of the house to ground it and something to provide interest for the 5 months of the year that aren’t the growing season.

Right now the beds you have are really shallow. With a house that tall and with the large overhang, you want beds at least 8’ deep to look proportional, and deeper may be better.

Any curves should be long and sweeping, not wiggles which are difficult to mow along and tend to look overly busy.

You want a tree diagonally off the right corner of the house (swing the bed out to include it) and likely a small one between the sidewalk and the house. You might do well with a large one to the left of the drive, but that area isn’t in your photos so I am not sure.

You don’t want a tree between the windows IMO. Perhaps a shrub with some size, but a tree will block the windows. For most of the bed, you want to keep plants below the level of the windowsill when mature.

If you want roses, plant evergreen shrubs at the back of the bed (but not so far back that they will touch the building when mature) and the roses in front. This will give you flowers but also something of winter interest. Be aware that summer blooming roses are often plagued with Japanese beetles here in NH so you may want a different flowering plant that they ignore. Or plant roses that bloom only in spring before the beetles emerge.

Before suggesting particular plants, do you have deer? Do have time and interest to spend in the garden? Have you thought about a budget?
