@LnzyHou I save eggshells and powder them in a coffee grinder, so they get those too.
Sometimes blue; sometimes pink.
@LnzyHou I've never seen a blue peonie - I do have pink white and red - might add some yellows.
Mom got blue by burying egg shells at the roots. Some say coffee grounds get pink
@Lucky188 Beautiful!

Gorgeous. My mom used to bury eggshells at their base to create color. We loved seeing them turn.
