Dark blue and purple orchid-like flowers. This plant is introduced and invasive. It belongs to the Mint family. (Photo taken April 30, 2013. I’m way behind on posting photos, so I’m going to add the actual dates I collected the photos, for the AFs who are trying to compare this year with last year—you know who you are!)
Creeping Charlie, Ground Ivy, Gill-over-the-ground, Haymaids (Glechoma hederacea)
Mint and blackberries could take over the world! Have finally (I think) eradicated the mint from the rose garden to be confined in pots. Have had no luck getting those pernicious blackberry roots to stop sending up their long beautiful vines. They look so pretty and innocent. But they won’t share!
