Sunflares - they would take over if not kept in their own enclosure.  

False Indigo - The flowers fall, leaving behind bright green seedpods that deepen into a deep, dark blue.  I will update with pictures come late summer.
 Roses - white, pink, orange and red - the pink smell the best!
 ... and strawberries!  Unfortunately, they never make it indoors.  The children and I keep our small patch picked bare at all times.  If we are in the garden, we are in the strawberry patch.
