My daughter lives in North London, UK and just sent me this photo of plants she bought for her window box. I've never seen it and she doesn't know what it is.
Does anyone know?
From the leaves and flower structure I would say that is the coolest color of primrose (Primulaceae) I have ever seen. Maybe someone else can give you more information as to the specific variety. WOW!
They are in the Thompson & Morgan seed catalog listed under Primula polyantha "Gold Laced".
