Vaccinium praestans

Vaccinium praestans is a herbaceous, slow growing perennial shrub, that can grow up to 20 cm (7.9 in) tall in an average growing season. The bark of the stem is a yellowish, gray color and grows almost horizontal with the ground.[1] It has small leafy branches, approximately 6–10 cm (2.4–3.9 in) in length, that extend out, away from its stem. Its leaves are shaped either obovate or orbicular around the head and then taper to a narrower base. These leaves are fairly thin but stiff, usually 2–6 cm long and are serrulate around the edge.[2] The leaves are known to change color several times a season, from bright green to a purple-red color The Vaccinium praestans flowers in June–July. Its flowers range from pinkish-white to pink in color with yellowish corollas, and are5–6 mm (0.20–0.24 in) in length. Later in summer It will fruit a delicious, juicy bright red berry, that can grow up to 8–12 mm (0.31–0.47 in) in diameter.[3][2] It is referred to as "the stinkbug berry" due to its characteristic, very pronounced odor that resembles the smell of bugs.

The plant is native to Kamchatka, Eastern Russia.[4] It ranges from Northern America to Eastern Asia, in spruce, fir and deciduous forests.[5][6] It is found in higher elevations and slopes, growing in mossy bogs, marshes and swampy woods, often off of rotting fallen tree trunks.[7] It is endemic to the Mountain Taiga region of Primorye, Kamchatka, Khabarovsk Region, Sakhalin, the Kuril Islands (Kunashir, Shikotan, Etorofu Simushir, Uruppu Keta), Honshu, and Hokkaido.[1]

Vaccinium praestans is a hardy plant that can grow in harsh cold climates. However, it requires shelter from strong winds and needs insulation from snow and leafs to protect its roots in freezing temperatures. It is best suited for slightly sandy, loamy soils. It also prefers moderately moist, mesic soils with a high acidity, ranging in PH from 4.5 to 6.[8] It can quickly become chlorotic if lime is present in the soil, which means it won't produce enough chlorophyll and its green leaves will become a pale yellow to yellow-white color.[9][10] It also does not like root disturbances or stagnant water at the roots, preferring moist, yet well drained soils but can not tolerate drought.[1] The plant can grow in semi-shady conditions, but fruits best when in full sunlight.

Vaccinium praestans is a part of the family Ericaceae, which includes species like cranberries, blueberries, and huckleberries. Ericaceae is a family of flowering plants known to be a part of the heath or heather family, usually found growing in acidic and considered infertile soil conditions. The word "Vaccinium" means "huckleberry" in Latin and the word "praestans" means "excellent" or "outstanding".[11]

The berry contains ascorbic (70–100 mg%) and benzoic acids, rich in flavonoids and other P-active compounds, also tannins and various microelements. Under- and overripe berries have significantly lower percentage of useful chemical components.

The berries this plant fruits are known for their ambiguous flavor, which however dissipates when the berries are boiled. The berries can be eaten raw, and exhibit peculiar gustatory characteristics: they are first sweet and then sour, then fade to a bitter, but salty aftertaste. In the confectionery industry, these berries are used in making jellies and jams, preparations of marmalade, soft drinks, and pastries.

The berry juice improves digestion and possesses tonic properties. It also helps alleviate common cold and flu. The plant and its berries find use in folk medicine, believed to help with prostate hypertrophy, fever, paralysis, edema, gout, and is used to treat hypertension, due to its effectiveness in reducing blood pressure. However, the berries can cause severe allergic reactions not only though ingestion but also through smell alone.[1]
