Amelanchier Lamarckii or Juneberry
Beautiful white blossom now appearing alongside the bronze coloured juvenile leaves.
These turn green as summer progresses then orange and red in autumn. The flowers are followed by small berries in mid summer, which turn from green to red to blue/black if the birds don't get them first. There are not many other 'small garden' sized deciduous trees/shrubs that gives so much interest from spring through to autumn.
