If you have the damp under control then any small evergreen shrubs you like the look of - and suited to the soil there otherwise, liking the exposure and climate should be OK. Visit some outlets and sniff around. Aim for mature height about 1 1/2 times the width of the bed where each is planted. Also use mostly small-leaved subjects, to get a more flowing and relaxing appearance rather than a lumpy and tense one.

Everything grows, heights represented on tags can be used as a guide keeping in mind that as enough time elapses the plants will grow larger.

We don't live in Texas nor do we have wet soil to deal with but we do grow some of the plants on your list. Bougainvilleas are frost tender and in zone eight ours dies to the roots every winter. They also are supposed to bloom much better if they are grown on the dry side during thier bloom period. We water ours in spring but then back off on the water once it has vined up from the roots and is ready to bloom. Don't know how well it will bloom with constant moisture and hope you are prepared to chop the spiny dead vines back every winter.

Ligustrum is quite large so hopefully you will be able to prune regularly because your space doesn't look very large. We don't grow azaleas as they would hate it here but my understanding is that they like moisture retentive acid soils with good drainage. I know a lot of texas has alkaline soils but maybe not your area? Also hope that with all your moisture you have drainage and the sun isn't too strong for the azalea.

We don't have Katie ruellia but the more common R. brittonia which is a bloom factory but it dies to the ground in the winter.

Some moisture lovers that you might check out are calla lily (Zantedeschia), Siberian Iris, fiber optics plant (Isolepis).

What a mess and the landscaper is clueless. Are they from WalMart? Pink flowering shrubs against red brick? When I visited Dallas I went to a couple of nurseries so I know they have a multiple stemmed small trees, a shape similar to to crape myrtle, that would fit into that niche and would break up all the red. Indian hawthorne would do good and so would Siberian Iris, but most everything flowers. What about a low growing holly planted high in the hole? You don't need too many varieties planted in that niche or it make the brick look worse and really bother the eyes.

I agree with Bullthistle - yikes, lots of pink against a red brick house with red rock is not a good idea.

I not from the south but I think I would get another opinion - perhaps from someone who has a more solid design background. But bear in mind it is also important to properly space plants - he seems to have a rather long list of plants that's he's trying to pack into that small area.

You have a beautiful brick house why cover it up with garish sounding plants. My motto is a little goes along way especially with the stronger colors like red, dark pink, chartreuse and some of the variegated plants.

I am from Texas-- and all those suggestions (besides the ruellia) will get TO BIG!

Even if he only put in one of each they'd get so big you'd never be able to walk on your sidewalk with out being eaten.
Bougainvillea is an arching shrub/vine with nasty thorns that would NOT stay put there. One ligustrum planted there would eat your foundation as a snack.

You might be able to squeeze in one or two azaleas (unless they're dwarf) and one or two Indian hawthorns in (again, unless the Indian Hawthorns are dwarf!)

Dwarf azaleas and dwarf Indian Hawthorn with an edging of Katie ruellia would be fine.

"Pineapple guava OR ligustrum"--what, whatever he can find cheapest?!
These bushes are NOT interchangeable, and I can't think that azaleas and the guava would both do well in the same place because they have different light requirements.
BTW--which side of the house IS this (North, East, South, West), and is there shade from trees?

Oh--and please, skip the rock in Texas. The only plants that thrive in the heat to grow out of rocks are weeds.

Bottom line: The builder is doing you NO favors, here!
Demand Better!

Since you are to be compensated for this snafu - make up a list of appropriate plants that you want to have and tell whomever that you will plant them yourself. Then plant them elsewhere in your yard where you might want to add something new. The bed that is the focus of this thread is quite a small space, it's conditions seem a little more complicated than merely throwing a builder's special into it.

I don't know Texas plant life, but there should be a host of native plants that would thrive in a moist spot. Lots of info on the web by searching native plants, plants for wet areas, etc...

A question...is that little flower bed the only wet spot in the yard or is it also damp on the other side of the sidewalk and out into the lawn area?

Is that a current pic? During their 'fix' of the water, did they do something about the downspout that is draining directly into the bed?

I think I'd tell the builder that I prefer to work directly with a nursery on plant selections and he can pick up the bill.

I wonder how a decorative metal trellis on the large wall would look? Then a few plants, grasses in front of it. I don't think you should use plants to gain privacy but instead use a combination of blinds and drapes. Shrubs covering those windows won't look very nice, IMO.

Another question...did any of the "experts" participating in the study of your moisture problem conduct humidity readings in your house using a sling hydrometer? Suggest you not accept any settlement with your builder until such tests has been done over a period of several months to make certain that interior house humidity is within 'normal' limits.

If I take the conditions at face value and the area is "very moist," you are going to need to use specific plant material that likes those conditions. So you or someone with more knowledge should try to determine if it's actually a bit bog-like, with poor drainage. There are great plants that like that, that I have no hope of growing in my yard. Most of the plants you listed are actually drought-tolerant, except azaleas and even they require excellent drainage and not soggy soil.
