Found out that there is a sparkleberry tree and was childishly disappointed when I saw a picture of one (it's a perfectly nice tree, but not what I was hoping for). Any names of stuff disappointed you?
Where I live in Eastbourne there's an area called Shinewater - a lovely name which conjures up mental images of dappled sunlight playing on the ripples of a lake...
The fact that the locals refer to it as Crimewater should tell you all you need to know about what it's really like. :-(
