An Updated Flower Bed

This garden has bothered me pretty much since I started it about six years ago.  What was I thinking?  The problem  then was we had no rain gutters and all the rain poured off the side of the house and ruined any plants I had in there.  So my solution was to make it very narrow and eliminate the issue.  Now that we have rain gutters it was time to expand it back to the original size. 

Yesterday morning was the day to start this project.  This picture was taken about an hour into it.  I already had pulled out the edge pavers.  After many hours of digging, shoveling and measuring, it all came together.

This is the picture from this morning.  After a whole day of work and many many sore muscles I didn't know I had, it was finished before dark last night. 

And now  for the next step.  What do I plant in it?  The green you see there is phlox.  It did ok but didn't flourish.  Do I plant annuals?  Perennials?  Shrubs?  It faces the East so has morning light but not the hot afternoon sun.  And it also tends to be dry and well drained.  I welcome any suggestions and in the meantime  I am on to finish another garden project I started three years ago and never finished.
