An article in the Gardening section of the Dallas Morning News by Mariana Green regarding a new book named "One Writer's Garden: Eudora Welty's Home Place" looks really interesting; even though this is Mississippi, it ought to work in Texas too!

I'll attempt to post the address, don't know if this will work, have never tried it:

Doesn't look like it worked, but the book is available on Amazon.
