It is a medium to large deciduous shrub or small tree growing to 5–12 m tall, with dark brown branches and greenish twigs. The leaves are opposite, 4–10 cm long and 2–4 cm broad, with an ovate to oblong shape and an entire margin. The flowers are small, with four yellow petals, produced in clusters of 10–25 together in the late winter, well before the leaves appear. The fruit is an oblong red drupe 2 cm long and 1.5 cm in diameter, containing a single seed.
Uses
Fruit
The fruits when ripe on the plant bear a resemblance to coffee berries, and ripen in mid- to late summer. The fruit is edible, as used in Eastern Europe, UK, and British Columbia, Canada, but the unripe fruit is astringent. When ripe, the fruit is dark ruby red or a bright yellow. It has an acidic flavor which is best described as a mixture of cranberry and sour cherry; it is mainly used for making jam, makes an excellent sauce similar to cranberry sauce when pitted, and then boiled with sugar and orange, but also can be eaten dried. In Azerbaijan and Armenia, the fruit is used for distilling vodka, in Austria and German Alps is used for distilling :de:Dirndlbrand|Dirndlbrand, in Albania and Bosnia and Herzegovina it is distilled into rakia. In Turkey and Iran, it is eaten with salt as a snack in summer, and traditionally drunk in a cold drink called kızılcık şerbeti. Cultivars selected for fruit production in Ukraine have fruit up to four centimetres long. It is eaten in Eastern Europe in many ways including as a traditional medicine. The fruit of C. mas has a long history of use in traditional Chinese medicine in which it is known as , and used to retain the jing.
Flowers
The species is also grown as an ornamental plant for its late winter yellow flowers, which open earlier than those of Forsythia. While Cornus mas flowers are not as large and vibrant as those of the Forsythia, the entire plant can be used for a similar effect in the landscape.
Wood
The wood of C. mas is extremely dense and, unlike the wood of most other woody plant species, sinks in water. This density makes it valuable for crafting into tool handles, parts for machines, etc. Cornus mas was used from the seventh century BC onward by Greek craftsmen to construct spears, javelins and bows, the craftsmen considering it far superior to any other wood. The wood's association with weaponry was so well known that the Greek name for it was used as a synonym for "spear" in poetry during the fourth and third centuries BC. In Italy, the mazzarella, uncino or bastone, the stick carried by the butteri or mounted herdsmen of the Maremma region, is traditionally made of cornel-wood, there called crognolo or grugnale, dialect forms of corniolo.
Name
Cornus mas, "male" cornel, was named so to distinguish it from the true dogberry, the "female" cornel, Cornus sanguinea, and so it appears in John Gerard's Herbal:
Garden history
The shrub was not native to the British Isles. William Turner had only heard of the plant in 1548, but by 1551 he had heard of one at Hampton Court Palace. Gerard said it was to be found in the gardens "of such as love rare and dainty plants". The appreciation of the early acid-yellow flowers is largely a 20th-century development.
