Not sure where to put this, but I guess I'll give a nod to medicinal and herbal/beer brewing use this particular plant has enjoyed in the past (and present?).
I noticed a variegated form in the middle of my Spiral Garden. I thought it was unusual, but there are a bunch of photos on-line... I think mine looks a little different, though.
...RIGHT-most photo is a normal one, though this one is showing purplish foliage -- maybe due to the dip in temp we just had.
