This is bizarre.
Last year I planted a two-year-old [vital missing word here - 'campanula'}] which had white flowers. This year the same plant has rich purple flowers. I'm very happy as I much prefer purple to white!
And also a penstemon last year was a pale mauve. This year it's a bizarre pale blue and white.
Can a plant suddenly change like that? I'm very confused! ???
edit coz i am an idiot!
Aqui, you planting 2 year old children in your garden now?!
whoops - missed the vital word. Will go back and edit it...
They have probably 'reverted' this is quite a common occurence with some 'hybrid' species.
