from green to blue

Hi Charles 
Here some info on your question A plain green wild  plant will rarely 
sport to blue, Why? because if it does  it will be a sport due to a 
mutation ie a change in DNA  A sport due to a muation is as I 
argued earlier a very rare occasion. I dont think there are any 
examples ( or is tokudama originally?). A better chance is when 
you have a ( nearly) green plant for a blue x green cross In that 
case you can get a blue sport due to a mitotic recombination a 
more frequent occurence. The cases reported seem to be the 
following. Halcyon is a green x blue cross. A mit rec in its outer 
layer only , resulted in a green sport. However the second layer is 
still blue so tc or a sport due to chimeric rearangment can bring out 
the blue again in these ""green"" sports like Devon Green!
