Fields of Blue Bonnets are One of the Most Beautiful Sights When Driving Throughout Texas. I remember when I had just moved to the south and I saw a beautiful blue field. I saw multiple cars pulled over and people were taking photos in the field. Just a beautiful sea of blue and when I finally got close to this flower I thought to myself “How beautiful would these be in a vase at home?”. My friend who is a native Texan said “Don’t pick it it’s illegal.”
