Evergreen (or at least interesting to look at in the winter).
Can handle deep shade (north side of house in a yard full of trees).
Can handle 7b cold hardiness.
Can handle 9 heat zone and occasional drought.
3-6 ft high.
Basically, this doesn't seem to exist according to my research.
Oh, and nothing tropical will live in my North Texas garden so I stopped trying.
Denton just has that plains prairie thing goin tho. Still, I see evergreens in Illinois and you can't tell me it doesn't get as hot as Denton- windier too. If you have a whiterock soil, cedars grow, junipers too.
I am in 8b, but I see many viburnums in the nurseries. They grow well in many states. They are evergreen with various kinds of spring blooms depending on the variety. You might want to ask your local nurseryman/nurserywoman if a variety would grow for you. I think they are a real nice shrub.
Larissa, I'm looking for something similar for a deep shady corner in a friend's yard. Have you considered something like oakleaf hydrangea? When you do the research most will say they need some sun, but I think in Texas they do okay in full shade. I think it will eventually get taller than you specified, but you can prune them into a bush, and there are also dwarf varieties now.
I'm just now seeing this, but can offer a couple of suggestions.
We have variegated Euonymus (yellow & green) along the front of our house that receives afternoon shade, that we keep to around 3'
There's also a white & green variety.
Our Junipers have really been so satisfying on either side of our front steps.
They are under the eaves of our front porch, and are in mostly shade.
Our Gardenia is definitely evergreen, but is in full sun. It's really rewarding.
