A little bush not yet 20 centimeters high, it is easy to miss it. Only when you take the time to really look you notice the Yellow Restharrow (
Ononis natrix) has beautiful flowers.

When the butterfly-like flowers open they show fine lines in red on yellow. The greyish down in the picture are the glandulous hairs that cover leaves and stem; if you touch the plant it sticks on your fingers. And you'll discover the smell, a bit nasty. Maybe the rabbits don't like it either!
Restharrows are perennial plants with long and tough roots, farmers don't like to find them in their fields.
