During the summer the flowers was blue and when the 10 degree celcius night are coming only the hatsu arashi next to my house , in container, produce all day long this kind of flower.Other plants in the garden, where it's supposed to be colder, still make blue flowers.
so ! you are right it's a problem of temperature

For me it was the way to ask the question :
how to choose a flower to begin a new line , a new type of flowers ?
using a " natural " mutation it's the simple way for a beginner.

a flower how " care " a mutation will pass on this difference ?
and with this " heavently blue " too ?
