I haven't really been doing any selective breeding of the Lavender Blood Reds. They are still rather new...... But like most (if not all, so far) of the Lavender derivatives, they will reach a bloom stage where their colors just explode, then it will fade out with age. Now I AM working on strains that I hope will retain that intense coloration further into maturity, but it takes quite a bit of time to see if you are getting the results you are hoping for.
