You don't say where you are. I grow Hostas under my Oaks in eastern
Ontario. They love it there.



We have daylilies under ours, also sedums and creeping phlox, here in
midnorthern Ontario (Zone 4b). We planted the sedums when the tree was
a sapling so they had lots of sun then, but they seem to have adapted to
the shade as the tree grew. The lawn doesn't like it under the oak,
though, a combination of shade and the effect of the oak on the soil
chemistry, I think. If anyone knows of grasses that don't mind the oak,
please post.
