I used the new feature to search for plants in My List that include 'unusual foliage color' - and the majority of hits have just plain-jane green leaves - mints, lily of the valley, darmera, skullcap, the list goes on. Some have really large leaves or an interesting shape to them, but unless they do something different in another zone, they're all just green. Maybe the field should be changed to 'unusual foliage' which appears to be how it is currently being used, with perhaps a line to clarify what the unusual characteristic might be (variegated, feathery, huge, etc.).
Edited to add: no one has commented on whether Lonicera has unusual foliage. Mine is just now emerging and it does have a bit of a reddish tinge to the new leaves, which I suppose could be termed unusual.
