Y'all know how I love to photograph and see the Texas Wildflowers. While sitting after the noon-day dishes were done, I was curious to find out if poppies would grow in my area. My sister sent me a photo of her red poppies in bloom in her front yard. We texted back and forth about them, and she said she'd send me some seeds this Fall. I didn't know if they'd survive the damp air. It's worth a try. So, I look forward to attempting to see if they'll 'take' from seed. Anyway, my point of this is while I WAS LOOKING online, I found a great site. All about identifying [with photos] wildflowers. Not only Texas [which this site has Texas divided into areas of the big state]...but, EACH state in America!! You may be interested in it, so I thought I'd share the links.
