Sneezy Walk

Stayed indoors all weekend until 5pm today when I ventured out for groceries at the Lenham store (sensibly only allowing two customers at a time) followed by a 1.75 mile walk.

I took a route through the church graveyard and out into the fields along the footpaths. I ended up half a mile along a field full of yellow blossom when the sneezes began. Hayfever has arrived!

I saw a few dog walkers at a distance who smiled and waved. The dogs looked blissfully happy.

Can you help me identify the plant? Is it field mustard?
