These dark, "fingery" clusters floating in the tree branches sure catch your eye... especially in the winter time.
I didn't take note what kind of tree was hosting these witches' brooms, but I'm pretty sure it's a Juneberry tree (Amelanchier sp).
Witches' brooms are dense, abnormal growths of branches.
Here is a picture of a smaller witches' broom.
Apparently, it is fairly common for the brooms on Juneberry to be caused by the fungus, Apiosporina collinsii.
Not very far away from the witches' broom decorated Juneberry trees, was this witches' broom in a Pitch Pine.
I planted a witches broom at our "old" (previous) house...see the Bird's Nest Spruce to the right of the front porch and left of the ornamental grass?
Can you see it now.... the wild, mutant miniature... high in the tree, waiting to be cut, brought down to earth, and grafted and trained into something beautiful?
Mite bitten mutants, anyone?
Or maybe I should say, "Could you make use of a mold molded mutant miniature"?
At any rate, there are some beautiful bonsai bouncing in the breeze... high in the boughs of the forest trees.
