A polarising filter can help with foliage. If you use a uv filter on a uv sensitive colour you can see the high amounts of UV light too. Most cameras are only a little uv sensitive but I can't see how it couldn't be a factor with foliage.
This photo is taken with a filter that allows a little more than UV light through, without the filter it would appear out of focus because UV light is travelling on a different wavelength and the lens is made to focus the visible light spectrum.
