Where we're celebrating those iconic trees -- have become symbols of Washington and spring time. They're the cherry blossoms and joined by and McClellan who's written two books about the cherry blossoms. And as an all around expert. On -- And so much for -- -- today my pleasure. It's a look at these trees and just think that they -- beautiful. And and love them just for that but in reality their symbols of a grand international friendship that's right Hayward gets the original ones were -- from the city of Tokyo -- the city of Washington the first -- came in 1910. And honor of First Lady Helen Taft. But what they sent were older trees and of course treated in the ground have bugs and worms and all sorts of pests so that Department of Agriculture. Inspected them deemed them impossible and had forced him to be burned. Decision -- yes the decision was made by president tapped himself whose life was so instrumental happening in our people were crushed it was just awful. And there was a young diplomat -- to tell -- -- of Tokyo what happens he said. -- seems to be your first president Washington. Had a problem is cherry trees that he overcame it. Weekend to -- about next year they center 3000 they're waiting to the issue of -- we -- today it's really interesting that. First Lady Helen Taft had such an interest. In these trees and in Japanese art in general how did she come to have that appreciation she visited Japan on their way to Manila. Because they were based in Manila for several years mrs. Taft had seen the trees not -- -- -- you know they were planted and -- -- Washington which was just being under construction at that time. Would be a great place where where was she right -- right.

Mainly they have to -- them and -- -- make sure that their main branches are strong and that. Other branches that are -- cut off for tweaks that are growing where they shouldn't are removed. And then they also air raid around the -- because the trees breathe through their -- And we are actually hurting the trees off the -- every time someone -- a blossom. That tree will never grow there again it won't bloom there again it won't have to -- and that's. And people -- the blossoms all the time exactly we all -- and today actually there wide spreading trees don't grow very high actually it's a funny story. And 1912 when they plan of the gift -- -- came with instructions it was a Japanese and nobody -- -- tremendous.
