This plant was a volunteer to my garden about 3 years ago and got rescued and moved by me from its original appearance in an unruly spot in the yard. I moved it to the flower bed beside the patio where it was overpowered by an overgrown oregano plant. The oregano has been moved and lo and behold this little plant is covered in the most beautiful little flowers. As you can see from the pics the flowers are smaller than my fingernail, about 1 cm or less across. I think you would describe the colour as cornflower blue. The leaves are a pale green. Any info you can give me would be appreciated - it's a lovely little thing and I'd like to take proper care of it. Thanks.
