I was weeding by the one lone daisy plant that has come up so far this year. I accidentally broke off one of the flowers (luckily with a long stem.)
I took it inside and put it in a small vase with water. Within 24 hours the white daisy was painted a pinkish-red.
Oh yeah, I put a touch of red food coloring in the water. I forgot to mention that? Day two with the light shining in from the window behind the flower the veins of red pop out from the white petals.
