Cherry Blossoms in D.C.

I'm from the middle Georgia area, and there's a really great Cherry Blossom Festival a few miles up the road in Macon. Virtually all the cherry trees there are of the Yoshino variety. We were in Washington D.C for the 2012 festival there, and it was quite a treat. Many cherry tree varieties dominate the Tidal Basin, and mingled throughout are other flowering trees, including crab apple trees. Absolutely beautiful! I hope to make it back soon!

The paleness of these blooms in the back leads me to believe they are Yoshinos. I have no idea what this beautiful pinkish-red blooming tree is! At first I thought it was a flowering crab apple tree, but upon closer inspection, I ruled it out. If you know, I'd appreciate a comment.
This appears to be the Weeping Japanese Cherry tree, offset by a Weeping Willow tree along the Potomac River.
The Weeping Japanese Cherry tree can be seen behind this mature tree.

I believe these are Akebono Cherry blossoms. They are very similar to the Yoshino Cherry blossoms, but perhaps a little "pinker". I'm no expert, though.

These gorgeous blooms are from the Shirofugen Cherry tree, according to the sign in front. They are like double blooms, with much larger buds.
This is another "double" blooming cherry tree, or properly called a Shirofugen.

Walking around the Tidal Basin, take time to look in all directions. Here, you can see the Jefferson Memorial in the background.
Crab apple trees bloom alongside the cherry trees, making for a colorful display.
Looking up through the cherry trees through my 200mm lens creates a delicate photograph. It resembles a watercolor, don't you think?
