Uva Ursi is a small perennial shrub that typically grows at high elevations. In Latin, Uva means "grape," and Ursi means "of the bear;" hence, we have the herb's common name, Bearberry. Bears like eating the red berries, as did Native Americans. Most commercial Uva Ursi is grown in Spain, where the herb's Spanish name, Manzanita, means "little apple," as the berries look like the fruit. The parts of this herb used medicinally are the leaves and the berries.
The generic name, derived from the Greek, and the Latin specific name, UvaUrsi, mean the same: the Bear's grape, and may have been given to the plant, either from the notion that bears eat the fruit with relish, or from its very rough, unpleasant flavour, which might have been considered only fit for bears. It first appeared in the London Pharmacopoeia in 1788, though it probably was in use long before.
The much-branched trailing stems are short and woody, covered with a pale brown bark, scaling off in patches, and form thick masses, 1 to 2 feet long. The long shoots rise obliquely upward from the stems for a few inches and are covered with soft hairs. The evergreen leaves are of a leathery texture, like a spatula in form, being rounded at the apex and tapering gradually towards the base to a very short stalk or petiole. The margin is entire and slightly rolled back and the young leaves fringed with short hairs. The upper surface of the leaf is dark, shining green, the veins deeply impressed, the lower side is of a paler green, with the veins prominent and forming a coarse network. The leaves are very astringent and bitter taste.
The waxy flowers, which appear in May, are few and are borne in short, drooping clusters at the ends of the branches. They are white with a pinkish tinge, 5-lobed, and somewhat bell-shaped in form. The corolla, about two-thirds inch across, is urn-shaped, reddish white or white with a red lip, transparent at the base, contracted at the mouth, which is divided into four to five short reflexed, blunt teeth, which are hairy within. There are ten stamens, with chocolate-brown, awned anthers. Smooth, red, globular fruits containing five nutlets follow the flowers. The fruit has a tough skin enclosing an insipid mealy pulp, with five one-seeded stones.
Bearberry is a native to continental Europe. It is distributed over the greater part of the Northern Hemisphere, being found in the northern latitudes and high mountains of Europe, Asia and America. In the British Isles, it is common in Scotland, on heaths and barren places in hilly districts, especially in the Highlands, and extends south as far as Yorkshire; it grows also on the hills of the north-west of Ireland. In America it is distributed throughout Canada and the United States as far south as New Jersey and Wisconsin.
They preferrs a habitat of heath lands, shady undergrowths and damp conditions. Bearberry is found growing mostly in sandy and gravel rich as well as dry soils in Europe.
Autumn is the season for the harvesting bearberry leaves in most areas where the plant is used in herbal medicine. During the autumn, the berries are also sometimes harvested along with the other parts of the plant, and though they are neither tasty nor particularly palatable, these berries are still used as minor fruits by people in some places.
This herb does not transplant well because the sand falls away from the root in the process and expose them.
Soft wood cuttings 2-5 inches long and deeply planted in pots of sand with little peat, kept moist outdoors or in a cold frame over the winter should be rooted by spring. Longer hard wood cuttings taken in winter may be rooted similarly in the green house.
By layering in summer in a sandy soil, perhaps in flats.
Seed Collection and treatment
Seed taken from the berries when ripe may be sown 1/2 to 3/4 inches deep in flats of sand and peat, and kept outdoors for two or five years before germination occurs.
The waxy flowers, which appear in May, are few and are borne in short, drooping clusters at the ends of the branches.
Pests and Diseases
No serious insect or disease problems. Some problems with black mildew and rust have been reported. This cultivar has good resistance to leaf spot and leaf gall. Most rusts are host specific and over winter on leaves, stems and spent flower debris. Rust often appears as small, bright orange, yellow, or brown pustules on the underside of leaves. If touched, it will leave a colored spot of spores on the finger. Caused by fungi and spread by splashing water or rain, rust is worse when weather is moist. Plant resistant varieties and provide maximum air circulation. Clean up all debris, especially around plants that have had a problem. Do not water from overhead and water only during the day so that plants will have enough time to dry before night. Apply a fungicide labeled for rust on your plant.
