Has Kew Gardens moved to Cornwall?

Kew Gardens has moved to Cornwall. At least that's the impression given by the Visit Cornwall tourism website.

The website is the main tool used by the Council funded Cornwall Development Company to market Cornwall and to attract visitors. Not surprisingly, there's a map with text that says:

Don't forget nearly 95% of Cornwall is now on Google Street View too.

If you click on that link, you are re-directed to Google Street View. So which Cornish location does it alight on? The Eden Project? St Michael's Mount? Launceston Castle?

None of these, but that well known Cornish attraction Kew Gardens - 200 miles away in South West London.
