Gardeners' Notes:


On Feb 25, 2005, ADKSpirit from Lake Placid, NY (Zone 4a) wrote:

The photo I posted is of a beautiful little wild flower that grows up here in the Adirondack Mountains. Every description I've seen lists it as a Wood Sorrel. It thrives in the shady, moist woodlands acting almost as a ground cover. It can also be seen growing on rocks and in rock ledges and moist cliffs. The one in the photo I submitted was growning on a rock beside a well-traveled hiking path.

Mountain Wood Sorrel is native to the rich, moist woodlands of North America where it grows in areas disturbed by logging or forest fire. The foliage is composed of basal leaves made up of three clover-like leaflets. There is no central stem. The flowers are white to pale pink with purple veining, occurring from May to July, then followed by round capsulated seed pods.

This hardy oxalis adapts well to the garden, especially useful in filling in around trees. It reproduces mainly by cloning its scaly rhisomes, so it can become invasive. O. montana is closely related to O. acetosella which is native to Europe.
