Thanks for your reply and sorry for my lack of info. They will live in an area that gets late day full sunlight. We will have drip irrigation installed for this area. I guess sea grass wasn’t the correct term, it is ornamental grass (like reed grass). Ive attached a photo of the entryway. The hydrangeas, grass and other suggestions will go where the existing plants are. Thanks again for your help.

Hi J, NHBabs is giving you great advice....stay away from the Endless Summer Hys ....here is a picture of some of the Hys she mentioned(Annabelle, ivincibelle Spirit and Incrediball) and guess what it’s SNOWING

With the late day sun, you want to plant one of the panicles hydrangeas (H. paniculata) since they will tolerate more sun while continuing to look good. The other two species will often droop in late afternoon sun, especially with the white wall adding reflected light. Choose one whose height won't get taller than the bottom of the windows. Check out Little Lime, Bobo, and Little Quickfire as three of the smallest.

Any controllable evergreen perennial or groundcover would be fine with this. Check out Veronica 'Georgia Blue', Hellebores, Carex 'Ice Dance'. I would also add some evergreen shrubs as well, as opposed to taller grasses since I can't picture the combo of the rounded Hydrangeas and the upright grasses looking cohesive. I would use the grasses elsewhere in the yard if it were my yard, perhaps where you could see them from a window from indoors for a nice view.

Thank you so much. Let me look into these. Any suggestions for complimentary evergreen shrubs?

I can't tell how deep your beds are front to back. If they aren't at least 6' deep, plan to make them that deep or more to allow space for the plants and so you have a foot at least behind the mature shrubs to get in to do cleaning, painting, or other maintenance and to let the building dry and not have wet foliage against it all the time. Some of the smaller Rhododendrons could work such as Checkmate or dwarf conifers that won't exceed your space, perhaps some of the smaller Chamaecyparis AKA false cypress. I would go to local nurseries (not big box stores) and see what conifers and broadleafed evergreens they have that will remain small. Then look up suggestions on Missouri Botanic Garden's Plant Finder as they will give a better size estimate than plant tags and will also discuss any issues they have. On the far left end of the bed, you can widen the bed to make a farther out, rounded area to accomodate a larger shrub or small tree there, and use a similar plant to the right of the garage if there is space for both access around the building and a shrub.

You are a wealth of knowledge NH. The beds are 4 feet deep and there is an existing walkway that wouldn’t allow for widening. I’m not too worried about the siding of the house as it’s new construction and they used cement board siding which I believe is very much indestructible.

I love the the idea of wrapping the bed around the corner. We have an a/c unit that you can see from the street and that would help in hiding it. Good tip about duplicating that look in the other side of the garage.

Since your house isn't symmetrical, the beds need not be either, so I would consider deepening the left side at least. You won't have room for any other H. paniculata than Bobo in the 4' bed since the other hydrangeas I listed will be too large, though in my garden I grow H. serrata 'Tuff Stuff' in a good amount of sun, so you could try that if you give it regular water.. It is a lace cap, and in my garden doesn't get larger than about 3'. If you want variety, on the left side you could fit one of the slightly larger panicled hydrangeas if you make it a bit deeper. Check out Little Quickfire. In my garden the large version of Quickfire starts blooming the first week of July and doesn't quit until hard frost. It starts white and slowly shades to pink as does Bobo, though the flower clusters have a slightly different shape.

Wow. This is quite a challenge. Thank you for your wisdom...I have a lot more research on my hands.
