I planted this the fall of 2008. It survived (always a plus in Alaska) the winter, and became very healthy and filled in nicely. It is in full sun in front of a bed. I gave it a 'haircut' about mid-summer (July for us) and it put out more blooms. Will probably have to split it up this summer 2010. Plants for free!! Yeah.

In my opinion, the prettiest of the lamiums. I have several others and this one is my favorite. It has the biggest leaves and flowers and spreads very nicely. After the first bloom period passes in late spring, cut it back and it will put out fresh growth and rebloom. If you don't cut them back [any lamium] they get very tattered and nasty looking. Great groundcover and/or specimen plant.
