Cherry Blossom Investigation

A closer inspection of this tree's foliage reveals some time and heat is required before the spring show begins. I like keeping tabs of the different streets around the city and when the blossoms bloom and whether they are more pink than white.  I prefer the whiter ones.  Some streets like 23rd and MacDonald where Trafalgar Elementary School is (the school I went to) have trees at one end that bloom before the other end of the street.  The trees also get progressively pinker or whiter in hue depending on what end of the street you're looking at.  Makes you wonder about soil chemistry and what it has to do with it...  A mystery.
