This gorgeous specimen plant is brilliant in the back of a shady border or at the ponds edge, and hardy to zone 3. They get 3 feet tall with a 4 foot spread, and heart shaped leaves that can be a foot across.  The foliage emerges burgundy with the leaves turning dark green on the top side, but holding their burgundy color on the underside and stems.  Golden to orange/yellow daisy-like flowers emerge in July.  Desdemona likes wet soil, and will benefit from part to full shade; but really this architectural beauty is quite easy and will do fine in nearly any conditions.  They will take some sun and do fine with less than optimal water.
