I have a 4 x 15 foot raised bed that I plan to acidify this fall for 1 or 2 azaleas I want to plant in the one corner. I might try a blueberry beside these although it would be an open invitation for the racoons to ravage the garden so I'd like to plant other acid loving perennials and/or grasses in the rest of the bed. The bed is primarily southfacing although it always has dappled shade in the corner reserved for the azalea so it gets quite a bit of sun. Above the bed is forest with a viburnum and a euonymus edging the raised bed wall.

Any suggestions for other plants for this bed?

Thanks!
