Here is a page I referred to in another thread...

http://office.microsoft.com/en-us/clipart/download.aspx

Scroll all the way to the bottom.

Either pick a categore, or I preferred to write "garden" or "trees" in the search box.

You select items, and download them. Some are big, some are not. I really did not read the license agreement very thoroughly.

There's not tons of gardening things, but more than just a few. Use all kinds of search words.
