The blue ones were a pleasant discovery upon moving to the South. They're purple in SoCal and of course white in Utah and Eastern Oregon, and while both are very pretty, I prefer the color blue and the particular blue of morning glories is absolutely stunning.

As a very wee sprog, I apparently fed dandelions to the neighbor's dog. It was sheer luck that I didn't poison the poor boy that way, since dandelions are generally contra-indicated as part of a dog's diet.
