Petite blue flowers

Very pretty.
Do we know what type they are?

Not sure what they are yet.

Nice color. Looks like a cross between salvia plant and lobeila flowers. Is the stem box-shaped instead of round. Salvia have boxy stems :)

Hi Tastey, I took this at a public garden a little while ago, so I'm not sure on the stem. It was just a pretty and very small flower.
