No apologies forthcoming from me about being technical, but I also know that some people like surprises more than I do. I like some surprises too, but usually after the fact when things turn out better than expected. I still would be curious to know whether this pink cornflower is a one-off or whether a significant minority - or even a majority - turn out to be pink.
I will let you know. At the moment there is another bud out which is blue.
In this particular case my feeling is that the packet of seeds I purchased will be predominantly blue, but some hybrid seeds have crept in. Nothing to do with the pH of the soil. I treat my hydrangeas to alter their colour but have never bothered with testing. Observing the plants usually tells me what they need. It will be interesting to see if my theory about the hybrids is right, and just how many colours appear. Stay tuned.
