Since you already bought plants and are now faced with designing them in; I reiterate the idea above to move them around in their pots until you come up with an arrangement that suits the look you're trying to achieve. How deep is the bed and will it be widened? What is the sun exposure? Looks as if you have both sun and shade plants doing nicely together. With what you've purchased and if it is all to go in the existing space, a line up that appeals to your eye as to height, color, and texture might be the only possibility along with a front of the border fill-in with spashes of color like your begonias. The Blue Star Juniper should have an open, sunny location. It does not respond well to the encroaching floppy foliage of nearby herbaceous perennials and other shrubs. Slow grower, 3x3' in ten years or so if any of the guideline literature is reasonably accurate. The barberry, euonymus, and hydrangeas should have at least 3' of space - I only have the barberry which is easily controlled by pruning and I imagine the others are as well, at least for the short haul. Smoke Bush, being hardy in your zone, has the potential for some real size.

I love all the suggestions. I would like to also suggest a birdbath in the center. It would give the little bed a focal point, and when you have to take all the plants out, you can use the birdbath in another section of your yard. If I were keeping the bed... I'd put in an angel trumpet in the back near the fence, and let it grow into a small tree. Then I'd underplant it with pentas or a tough rose like a Knockout. I'd edge with yellow lantana, and I'd find a way to mix in some deep purple salvias. Oh, who am I kidding... I'd rip out all that grass and go absolutely berzerk! But for quick fixes, you've gotten some great suggestions. :-)

You're welcome. I should have mentioned that I considered them for my kitchen. (Thanks to Mtnrdredux who showed me pics of them in her lovely kitchen.) I really like the style, but needed some 8" pulls for some wide drawer stacks. The Hafele is limited to one size. I think about 5.5"??? While they didn't work out for the kitchen, we did install them on some built-ins in the MBR. They are of nice quality, though I'd have to say not as well made overall as the RH pulls I chose for the kitchen. The exposed screws are decorative only; they attach from the back like most pulls do.

The small brick half-circles are basically flower pots in the yard. Suitable for annuals and the occasional perennial and that's about it. Whatever suits your fancy. If you want to do landscaping instead, you need to make a 6' depth bed across the entire front. We don't know what the bed would do at the ends because we can't see them.
