The first thing that always flowers and provides bright points of yellow and red everywhere is the Creeping Bossiaea.
This spring, thanks to Jo from Trust for Nature, I have discovered our small bird orchids. The one above is just coming out, the one below is darker and has been out for a while.
Also this year we have rice flowers again, after a couple of springs with hardly any. Below is Twining Glycine (I think). It always grows up and around the bracken.
These bright red flowers are commonly called Running Postman. They only grow in one place, in the middle of the track, and you can't miss them!
