Advice needed on new garden bed
This is a newer garden bed on the shadier side of my house. The picture shows bleeding hearts and forget me nots blooming earlier in the spring. Right now it's June 1st, the spring flowers have faded and foxgloves are blooming. Along the side of the house are some hostas, Lilly of the valley, there are some lambs ears, day Lillie's, and a few purple salvia. You can see that there's a spot in the front of the bed that is empty. Any suggestions on what plants might be good to fill out this bed? I'm also a little concerned that after the foxgloves and bleeding hearts are done, there won't be a lot blooming during the rest of the season, so I probably should think about things that bloom later in the season, in partial shade, and hardy enough for zone 5b (Indiana). Any advice would be appreciated.
