This week the trees in Pittsburgh are putting on the green.
The flank of Mt. Washington is my favorite place to see it. All winter the hillside is a flat brown color without the look of individual trees but now each leafing tree shows up as a pale green crown. Some are white with flowers.
This appearance is ephemeral. Soon the leaves will be large and shady and the hillside will look uniformly green. So now while the trees are changing so fast here’s a close look at what they’ve been up to.
Above, in Schenley Park an Ohio buckeye leafs out. Below at a later stage the flower buds emerge. (*see the Comments for discussion on this tree)
The bitternut hickory is not so quick but its mustard yellow bud has begun a leaf.
The pignut hickory’s end bud is furry, shiny and enormous.
These catkins look like caterpillars.
(Dark bark, perhaps a sweet birch. Do you know what tree this is?)
And the crown jewels are the magnolias, native to Asia. This is a star magnolia. Wow!
