All photos on the Midwest Weed site are the property of Pamela B. Trewatha (unless otherwise noted). They can be used for single use, with permission, without cost for educational, web and commercial purposes. Most photos are available at larger size and higher resolution than shown on the site. Please contact me if you wish to obtain the higher resolution file. I also like to hear about where the photos are used, so I can list them in my photo credits. Thank you for your interest and assistance.

Send digital photos of your unknown weeds to see if we can assist you in their identification.
To person who sent two photos of a lawn weed last week (first week of May 2016): they were both corn speedwell; I'm afraid I lost your e-mail-- please re-e-mail me for more information. Thank you & I'm sorry for the inconvenience.
Are wild ornamental pears growing in your area?
Seedlings of ornamental pears (like Bradford, Aristocrat, etc.) have escaped cultivation in parts of the central U.S., and are rapidly becoming abundant and invasive to open woods, pastures and prairies in many areas. If you are seeing this where you live, please let me know approximately how many--
* less than 10 trees
* 10-50 trees
* over 50 trees
and in what habitat and county/state you have seen them.
Please e-mail me firstname.lastname@example.org
Thank you very much!!
