A very interesting effect. I've seen a number of these UV plant 
picturs, and often it's very hard to relate them to the flowers we 
see. A lot of the plant is made visible that we cannot otherwise 
perceive, and I think that is part of the additional 'mass' or 'bulk' 
that George speaks of.

It might be fun to try using different lighting (back lighting, 
different fluorescent tubes, etc.).
