Ah, true spring comes to Nantucket - the Shad have bloomed. And I'm sure the Herring are running at the Massasoit bridge, Night Herons standing guard like Egyptian paintings and Gulls circling.
Amelanchier canadensis - Shadblow, Shadbush. It only lasts about a week, very delicate blossoms and of course our weather is way odd this month.
I love how tender the emerging leafs are, and the red, almost blood, life force tinge.
They are a member of Rosaceae, have tasty fruits in a July - a good small tree or shrub for a bird habitat.
This is Amelanchier canadensis.
