Sproungy, hummicky grass

A very grey day and a busy one at work. driving home was the best blip option. So, spied a possible scene, a lay-by, pulled in (rather too sharply and car behind surprised), scrambled over verge in work shoes (now wet and muddy) and took photos through the fence, trying to be oblivious to passing drivers who must have wondered what on earth could be there. On making large, found the grass to be interesting. Don't know how to spell the word to describe grass that bounces you when you walk on it but I think Zebedee had it .... sproung, sproung, sproung boing, boing, boing.
