Wildflowers: 2 from roadside, Ontario

The first image was taken this week, there were about a dozen plants growing in standing water.

The second two were images of a plant from May, growing in sandy soil.

Thanks very much for any help.

Second is something in the family Brassicaceae.

 

Thanks Michael.

I haven't had any luck in that area but it is a big family. The flower is a bit similar to Yellow Foxglove but the plant is different.

The first plant has me stumped. There is a similar flower which is white called a Mimosa but otherwise quite different.

 

For the first one, maybe something in the Asteraceae, like Solidago caesia or Euthamia ?

 

The first plant is tufted loosestrife (water loosestrife, tufted yellow loosestrife), or Lysimachia (Naumburgia) thyrsiflora. The second one may be bitter wintercress (Barbaraea vulgaris).
