I've been looking for unusual colors in our plants. Of course you know that we have a lot of oranges and reds, and sometimes they get already boring. But if we just take time to look for the not-so-ordinary, we will find. And even if these are ordinary plants, the colors are not in our conditions.
Blues are difficult to find, this is a weed with very small inflorescence, of about 1 cm a petal.
This one is related to the blue flower, but this is much smaller of only 3mm per petal. It is purple. They are so dainty, i wonder what type of insects can see and pollinate them.
