Just a couple of follow up notes...
There's nothing wrong with the rhodie planted to the left of the porch - I'm just somewhat compulsive and obsessed with "balance" and I feel that a second "Ivory Halo" would offer a better sense of balance but I'll be the first to admit that I may be in need of therapy but that's a topic for a different message board... The green/gray in the "Ivory Halo" is the exact colouring of the house and the visual effect is that the dogwoods are an extension of the house and thus have a greater visual weight but now the weigelas really seem to be far to dark and to clash with the dogwood. Perhaps the "Shining Sensation" weigelas are just too dark and there isn't anything that is going to change that and it would just be easier to yank them out and replace them with three weigelas that possess a better green transition colour that works better with the "Ivory Halo" dogwood. The landscaping was just installed 3 weeks ago and it would be pretty effortless to remove whatever needed removing but I'm also concerned that at this time of the season all of the best shrubs are long gone and that I will probably have to wait until next spring to do whatever needs to be done. One lesson that I did learn was not to ever be intimidated by a professional "anything" and that I should have just trusted my own instincts because I now find myself wanting to change everything that the designer installed and replace it with everything that I originally wanted to install in my design. A lack of confidence can really be one's undoing and I should have taken a chance and failed rather than find myself in this current position. Sorry for the rambling but I'll try to subdue it to the best of my ability or to at least make it relatively amusing. Thank you to one and all...

I found this -

It's a "My Monet" weigela

and I think that it may just be the perfect solution. Any thoughts?

Nice, but can be finiky compared to other Weigela.

They benefit from late afternoon sun.

Can you post photos? I am a big fan of shrub dogwoods - they offer a much longer season of interest with their colored stems - so I'd be inclined to 86 the weigela :-) And I wouldn't replace with the 'My Monet's either -- too much variegation going on. And it sounds like you have enough burgundy happening so maybe just a green leafed shrub? I think a green transition is just what is needed, but maybe not so dark a green as the current wiegelas project. And maybe something evergreen as well, so the red dogwood stems really contrast in winter. Boxwood is a possibility.....good textural contrast as well.

Photos would really help :-)

Gardengal48 - thank you for your reply! That "86 the weigela" was pretty funny!
No photos yet but try to "picture" this -

Variegated red twig dogwood - in back between porch and front of the house; foliage green is exactly the same colour as the house;

In front of the dogwood are three "Shining Sensation" weigelas; planted in an arc; foliage is really dark green blended with burgundy;

My idea: plant "My Monet" variegated weigela (which are compact - 18" tall) in front/between the 3 "Shining Sensation" weigelas;

I guess the idea is Dogwood (variegated foliage) (1)

Let me know what you (or anyone for that matter) thinks.
Thank you also to whaas.
