More Wildflowers along Nature's Trail

As much as I love plants & flowers, I am no expert on them. Other than a few common names, I rarely know most flower's names. After finding these tall ones at the Massapequa Preserve last Sunday, I googled "purple wildflowers" into the google images search bar. I then scrolled through a wide variety of purple blossoms until I found a bunch that matched mine exactly. Dame's Rocket is her common name. I'd love to know how someone came up with that title! Sounds like another Google search is in store. Meanwhile thanks to Wiki I did find her technical name "..Hesperis Matronalis is a herbaceous plant species in the Mustard family".
