Right now, as I've grown tired of watering and it's not quite time for the fall rain to start, I figured this little sunflower would have a longer life inside in a vase than out in the yard. I let Sweetpea pick it and the roots came up, too.
“Can we put it in water with food coloring and see if it changes color?”
Yep.
So far we've just had a few random blue dots come through on the petals and where I tore off some dead leaves. In the morning, I'll convince her to let me cut the roots off to see if it sucks up some more blue water. I'll let you know if that changes anything.
