Colour change of flower on chives & hostas

Has anyone else experienced chives plants or hostas changing the colour of their flowers? 

I moved house in 2020, and they both used to give me purple or lilac flowers (Chives/Hostas respectively) but now they are both producing white flowers.  I thought maybe it was just last year, as they settled in, but it's the same this year. I find it very odd. 

They have no problem growing and all my other plants are the same, with the same colour flowers. 

I wondered if there was something I can do to get the colour to return.

    This could be due to a difference in the pH (acidity/alkalinity) of your soil.  There's some more information on this link: Reasons Flowers Change Color: Chemistry Of Flower Color Change (  I rather like the white chives!
    Wirral. Sandy, free draining soil.
  • Thank you for the link. It probably is the soil. I can see some of the plants adjusting after the move. I have also dug in new fertilised soil too, to help renew it because it was a bed that was full of Hydrangeas which have a very specific soil. 

    The white is certainly different. But I did like the purple chive flowers. I feel that I have sent them albino! LOL
  • Okay, I'm going to test the PH, as it will also inform me about other plants that I feel are struggling. Thanks again for the link.

    If there were hydrangeas in there before ,chances are that the soil is more on the ericaceous side.That could be your problem.
  • It explains why my Rhododendrons are all fine though! LOL but I do have a Pieris in there that hasn't changed colour and they like ericaceous. But I think the PH might be more suited to those types.
