Need ideas for a large dirt bed

[rennyboy]

I have a pretty large bed in the front yard that we recently cleaned out, put stone around and when spring rolls around we need to put some stuff in it. That's where I'm stuck, we are in Central New Jersey, it get's the sun for most of the day, we do have a sprinkler system so the bed would be watered regularly. Thanks
