what plants (flowering or non-flowering with good looking leaves) can be grown in the shade? i just moved to a new house and there is an area about 4' by 4'. it has soil and everything, but there are no plants there currently, so i dont know what could be planted there. the area is not too dark, but it is considerably darker than a well-lit shade. so what kind of plants could i plant there? by the way, im in houston, texas.
