Blossoming of leaves and flowers made a big change in the tree during the six
days in May. Look at the photos in the 3rd row to see the growth that
helped fill out this tree in just six days.
The Swamp white oak provides homes and cover for a variety of birds and mammals.
Catkins and leaves begin emerging in the middle of April. A few acorn caps remained on the tree during the
winter.Photo taken April 15.
Flowers
of the Swamp white oak emerge with the leaves. Finding that I'd taken 2 pictures
of this branch six days apart was an pleasant discovery, particularly since they
were taken at a time when there was so much activity. To see a better comparison
of these two stages of development, go to the
comparison page and open the Quercus bicolor in both the left and right frame.
Photos taken May 4th and May 10th.
All
of the buds don't necessarily open at the same time. Leaves and flowers on this
branch are more fully developed, than on the branch above left. even though the
photos were taken on the same day. Swamp white oak is monoecious; male and
female flowers appear on the same tree in May to June.
By
early May, the leaves have become more fully developed and the male catkins seem
past their prime.
The Quercus bicolor, gets its name from its two-toned leaves. The upper
surface of the leaf is dark green and shiny, the lower surface is white with
fine hairs. Unfortunately I don't have a photo of the under surface. The edge of
the leaf is wavy with 5 - 10 shallow lobes on each side.
I
don't have any photos of the fall color of the Swamp white oak, but this winter
photo shows leaves on the ground. Now the colors are reddish brown and white,
but they retain the "bicolor" appearance. This photo is not from the same tree
as the rest of the photos on this page.
