I am helping a girl scout troop restore a bed at their school in West Chicago. Du Page County. The bed was made in an open area between two large pine trees and a another large tree. I think the site is mostly shaded with sun only on the outer edges of the bed. Can you suggest any low maintenance plants for this site? Native plants for would be nice but I don't know if they can take some shade. Are there any grasses or other tall plants can take shade? Would Hosta, Sedum Autuum Joy and Cone Flowers be a good choice? Thank you!
