Cherry Blossoms and Dinosaur Bones

Abram went to the CAMWS conference this weekend. After we dropped him off at the airport, we killed time roaming around Ikea (where Owen wanted to look for forks), played at a local park, and headed to Tracy's.
Friday, we took the train ("engine") into D.C. and visited the Smithsonian National Museum of Natural History. Owen and I enjoyed wandering (and running) through the Sant Ocean Hall where we saw a model of a whale and a shark's jaws taller than me with teeth larger than Owen's hands. Our favorite part was seeing the dinosaur bones. Owen got sleepy and needed to nurse amongst the fossiles. After he was sound asleep, I got him on my back (still asleep!) and walked around the National Mall making a bit of vitamin D in the sun.
Owen woke up as we headed past the Washington Monument,

and we continued a very nice walk around the Tidal Basin under the cherry trees toward the Jefferson Memorial
Owen enjoyed the music and the Indian dancers there for the National Cherry Blossom Festival and also liked sniffing the fallen flowers.

We were really tired and glad to head back to Tracy's after a long day.
Now I'd just like to know if those trees will produce edible fruit or are these sort just ornamental?
