Don't ya just hate how these plants jump into your wagon and you have no control over them at all. It is an unusual one I have not seen before. I am sure it will be happy in its new home. Congrats on finding it.
My cart likes to fill up at Lowes too. Must be problem with the carts. :) They had a bunch of cones, not marked down, but not a single one had a tag on it. Mystery plants. I'll wait until they get marked down. Will take mystery plants for cheap but not at full price. Sure wouldn't mind the mystery to be Mount Hood!
