Gardeners' Notes:

I've tucked a few of these small starters under a shore pine where grass seldom creeps, weeds sometimes do, and despite the shade, is an area visible to a passerby. This past winter (their first) they were not evergreen, loosing their leaves and leaving small mounds of their stems. Advanced billing say they will take as much acidic shade as you can give them, lets see if it holds!

Positive because this was a 'no sweat' drop-in to my garden in Quaker Hill, CT. I just noticed it under a pear tree. Healthy, lovely, green. I have to move it (just a bit) due to building. Thanks for helping me identify it.

I have candied the rhyzome and some people like it and some not. It does taste like candied ginger with pine mixed in.
It makes a wonderful dense groundcover even in areas that dry out. Weeds don't bother it. It spreads about 6 inches a year. Very attractive groundcover.

In West Virginia, you can find this plant growing in the wild in small valleys with a streambed that stays damp but doesn't have a lot of water running through. I didn't know they were considered evergreens since I've only seen them out in the woods while collecting ramps (wild leeks) and at my home, under some trees where I've planted them and never in the fall or winter. It does make an interesting addition to a stylized "forest area" at your home and the blooms are very different.

They seem to be in bloom during the height of ramp and trillium season.

Dense patches of trailing, rooting stems hide the peculiar brown-purplish to yellowish single flower.

While not closely related to tropical ginger, the aromatic stems and roots were used by early settlers as a substitute.

Wild ginger (asarum caudatum) makes a great, low-maintenance, dense groundcover in woodland settings with shade to part shade and ample moisture. Its glossy evergreen leaves are handsome year round, although it is somewhat attractive to slugs. It has interesting, although inconspicuous, flowers which grow in spring under the leaves and along the ground. They are a deep reddish-brown and are pollinated by beetles.
