Got these yellow & red flowers growing in my back 40. Don't know what they are. Can anyone help? Thanks, don1
The yellow ones look like a cultivar of Black Eyed Susans (Rudbeckia); the blue ones are Bachelor's Buttons (Centaurea cyanus)
Blue ones are Cornflower: http://ip30.eti.uva.nl/BIS/flora.php?selected=beschrijving&menuentry=soorten&id=3872
