I love walking the fields in our neighborhood, especially before the mowers come, when everything full and lush. Texas is famous for its wildflowers, but when we started building our house I only knew the names of two or three. So I started taking photos just to see how many different kinds I could add to my 'collection'.
My favorite resource for identification is The Ladybird Johnson Wildflower Center. They have an extensive library of photos that is very easy to search.
