I need ID of 2 more plants/weeds coming up in a one time pasture.

I have an area down a hill that my husband used for grazing his horses when he was alive. Since he died, I have let it grow up and have found some interesting and beautiful plants in the area. I live in Eastern Kentucky. So far you have helped me ID Ironweed, Jewelweed and Viburnum. I also have Honeysuckle, Wild Raspberries, Poke, Goldenrod, Mimosa Trees and Maples. This fall I have 2 more plants for your viewing pleasure :-) and hopefully ID. Thanks for any help. Here they are...

    The top one is a butterfly bush.the second one is not ringing any bells. It looks like wildflowers that I am not familar with here in my zone.

    Yep, that's right the top plant is a butterfly bush.

      @Gail Sacchetti After your answers, I took a leaf and compared it to the one I bought and planted in the back yard and sure enough....that's it. I didn't know they came up like that...from bird droppings, I guess? It's not at all close to the one in the back yard.

    In some parts of the country butterfly bushes are considered invasive. I have about a dozen volunteers coming up in my yard from 3 that I actually planted.

    That top one is surely a butterfly bush. They usually multiply and are really pretty. In Ohio, we cut them down in winter and they grow back to a full and huge bush the next year. The second one looks like it may be St John's wort? Not sure but the flowers and some of those leaves look like it.

      @Sandy Harmon Thanks and I am glad you know what it is now. I like to know the names, even of the weeds.

    I think your yellow plant is coreopsis. The top is butterfly bush. Where are you located? For the yellow flowers, a wild flower id site for your state may be helpful.
  • Janet Pizaro Janet Pizaro on Sep 01, 2015
    I do not think the yellow is coreopsis. They have different leaves.

    Thanks everyone for your input. I think they have been correctly identified as a Butterfly Bush and St. John's Wort. Wishing you all a great day!

    That purple one looks more like Veronica. Here's an example. http://www.bhg.com/gardening/plant-dictionary/perennial/veronica/

    I agree with the butterfly bush and St Johns WOrt

    the purple ones look like flox.

    It is a Butterfly Bush. A darker color from the one I had so I guess the birds "planted" it for me. Thanks to all for your help
