Messy trees

I walked to the Supermarket first thing this morning.
On the way back my boots were covered in sticky stuff from the trees.
So were the trolley wheels.I scrubbed it off then sat under my tree.
What a mess it makes.The blossom is like snow.It was going in my cup of coffee.
I was sweeping the blossom up non stop.
Still it was alive with bees .They love it.Also butterflies.
Look closely at the top corner and you will see one (a magnifying glass will help)
