And the Sarvis . . .

The tender hues of new lilac leaves. . .
  Weeping willow's yellow-green
Pure white, rising from yellow . . .
Purple beads, poised to explode into fragrant lilac blooms . . .  
A daffodil's rosy trumpet. . .
 
And the Sarvis, blooming on the mountainside.  Amelanchier, also known as Service Berry, Shad Blow,  or June Berry.
  Jim, over at Cumberland Vistas, explains how the early blooming tree got the name Service (pronounced Sarvis) Berry.
