Red & Yellow & Pink & Brown

The above collage was filmed around the Bridgewater Canal .The red and yellow tulip at the Wharf .The small pink flower  ( I think some kind of rose ) has the added bonus of a spider if you enlarge it .As for the brown growth .This was along the water's side .Once again I have no idea .Could this be a reason why FF and I are not regular partners ? Any tips are welcome and I invite any of the blippers to name these flowers.
A very big thanks to Annie Biker Bear for hosting this challenge.
