Tree flowers

 White confetti on the path?

No, these are fallen petals from the blooming hawthorn - the may blossom

Most of the blackthorn is over, so I'm guessing that this bush is a wild plum.

White seems to be the seasonal colour.  Here below we have bird cherry, with white plumes of blossom almost like buddleia.

And rowan trees also produce white bunches of flowers, but you can distinguish them by the different leaves.

Soon we shall have the large flat creamy white flower heads on the elder bushes.  Just buds at the moment, waiting to burst.

  But the big old forest trees are often less showy.  The dangling flowers of sycamore, for example, are a greeny yellow.

If you get the chance of a close look - the flowers are usually up in the light and out of reach - notice that the 'helicopters' are already forming on the upper flowers in the spray, with the lower flowers being male and soon to drop off.
