Near my property line I have cultivated a lovely and large patch of Asarum canadense in the shade of my neighbors pine trees. The first plants originally appeared all on their own about twenty years ago. New neighbors have seen fit to chop all those trees down last week (at the peak of the polar vortex no less). So now the plants are in full sun. Is a shade screen necessary for them to survive?
