Good morning and thank you for reaching out to ask2.extension.

Maple trees not only take the moisture out, but a lot of the nutrients as well. No matter what you plant, in order to get a good healthy plant you will need to water and fertilize regularly.  I water my Hostas at least once a week.

You could try hardy succulents.   I have also used Hostas, and coral bells.  The coral bells didn’t make it.  My grass doesn’t grow under them as well.  I have mulched the area directly under the tree.  You could add statuary or something else besides plants if you don’t want to mess with the plants.

I found suggestions from others: euphorbia,sedums, lady’s mantle, day lilies and astilbe. 

Good luck!
