Dahlia from seed - the first year

My daughter grew a dahlia (and a bunch of other flowers) from seed last year.  She was proud of herself, I was proud of her too.  We left it in the soil where it was overwinter and it started to grow again this Spring.

Dahlias used to be a South American root vegetable with pretty flowers.  Somewhere along the way people stopped growing them for food and focused on flowers.  I have no idea how this one tastes, next winter when this plant is dormant, if my daughter is not looking, I may sneak a little taste.

I can hardly wait for it to flower again this year, such a lovely little plant.
