Horsechestnuts and Japanese tree lilacs

The horsechestnuts have lost their flowers, but the Japanese tree lilacs are starting to flower.

Hawthorn and hydrangea blooms

The hawthorns are blooming now.

Some of the hydrangeas are blooming too, but not all.

Cottonwoods

The cottonwoods have started putting out their cotton.  It drifts through the air.  Last year, I made note of this June 6, but I think it may have started earlier than June 6, I just didn't realize what it was until June 6.

Leaves are mostly out

The leaves have come out on the sycamore maple.  Now just about all the trees except ailanthus have leaves.

Also, the Miss Kim lilacs are starting to bloom.

Leafy horsechestnuts

The horsechestnuts by the Quad are beautiful with their spring leaves.

Spring has enlivened the view from my office

The area in front of my office is rich with color now, with the red of copper beech and crimson king maple, and the green of callery pear, spruce, and crabapple.

Copper beech

Red leaves have emerged on the copper beech.

Crabapples in April

The first part of April was cold, and there was little change in the crabapples.  This is what they looked like on March 30:

They look much the same in these two photos from April 6:

When I left work on Friday, April 13, I did not notice any change, but when I returned on Monday, April 16, they had started blossoming, although some were not yet open.

Two days later, on April 18, they were even farther along:

After a cold, rainy weekend, I think the crabapple blossoms are a little past their peak, although there are still lots of blossoms.  Monday, April 23:

April 24 was very windy.  The trees did still  have a lot of blossoms.

But overall, there are fewer blossoms.

Looking for the blossoms that used to be on the trees? Now they are on the ground:

On May 1, the flowers that remain on the crabapple trees are looking brown.

From a distance, the crabapple trees show mostly leaves rather than blossoms.
