Thats a lot of roots.!These cuttings were taken from a plant with incredibly blue flowers. We have a different 'Izu no Hana' in a different location whose flowers are pink. Hydrangea color is all about pH; assuming the genetic of the plant allow it to produce deep blue flowers, the lower the pH, the bluer the color.
Those are some very healthy roots.What do you use to root your cuttings. I usually use 50% peat moss, 50% perlite.
