Flowering Dogwood (Cornus florida)

Shrub
Benthamidia florida. Cynoxylon floridum.
Common Name Latin Name Plant Family
Flowering Dogwood
Cornus florida
Cornaceae

A red dye is obtained from the fibrous root[4, 95].

The peeled twigs are used as toothbrushes, they are good for whitening the teeth[4, 95, 102]. The juice from the twigs preserves and hardens the gums[4]. The twigs can also be chewed to make natural paintbrushes[102].

A black ink can be made from the bark mixed with gum arabic and iron sulphate[4].

The bark is very bitter, could it be used to make an insect or bird repellent[K]?

Wood – hard, heavy, strong, close grained, durable, takes a good polish and is extremely shock-resistant. It weighs 51lb per cubic foot and is used for making wheel hubs, tool handles, the heads of golf clubs, bearings, turnery etc[4, 46, 61, 82, 102, 171, 227].

  • Medicinal Use

    Flowering dogwood was employed medicinally by a number of native North American Indian tribes who valued it especially for its astringent and antiperiodic properties[257]. It is little used in modern herbalism.

    The dried root-bark is antiperiodic, astringent, diaphoretic, mildly stimulant and tonic[4, 46, 61, 95, 257]. The flowers are said to have similar properties[4]. A tea or tincture of the astringent root bark has been used as a quinine substitute to treat malaria[95, 222, 257] and also in the treatment of chronic diarrhoea[222]. The bark has also been used as a poultice on external ulcers, wounds etc[222, 257]. The glycoside ‘cornin’ found in the bark has astringent properties[213].

    The inner bark was boiled and the tea drunk to reduce fevers and to restore a lost voice[213, 257].

    A compound infusion of the bark and the root has been used in the treatment of various childhood diseases such as measles and worms[257]. It was often used in the form of a bath[257].

    The fruits are used as a bitter digestive tonic[222]. A tincture of them has been used to restore tone to the stomach in cases of alcoholism[4].

  • Edible Use

    Fruit – cooked. The fruit is not poisonous, but is almost inedible raw[226]. When the seed is removed and the flesh is mashed, it can be mixed with other fruits and made into jams, jellies etc[226]. The fruit, when infused in ‘Eau de Vie’ makes a bitter but acceptable drink[4]. One report says that the fruit is poisonous for humans[229]. The fruit is borne in clusters, each fruit being up to 15mm in diameter with a thin mealy bitter flesh[229]. The fruit is high in lipids, uo to 35% of dry weight[274].

  • Cautionary Notes

    There is a report that the fruit is poisonous for humans[229].

Cultivation & Habitat

Seed – best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed[80, 113]. The seed must be separated from the fruit flesh since this contains germination inhibitors[80, 164]. Stored seed should be cold stratified for 3 – 4 months and sown as early as possible in the year[164]. Scarification may also help as may a period of warm stratification before the cold stratification[80, 164]. Germination, especially of stored seed, can be very slow, taking 18 months or more[164]. Prick out the seedlings of cold-frame sown seeds into individual pots as soon as they are large enough to handle and grow the plants on for their first winter in a greenhouse, planting out in the spring after the last expected frosts. Cuttings of half-ripe side shoots, July/August in a frame[188]. Cuttings of mature wood of the current year’s growth, taken with a heel if possible, autumn in a cold frame. High percentage[78]. Layering of new growth in June/July. Takes 9 months[78].
An easily grown plant, it succeeds in any soil of good or moderate fertility[1], ranging from acid to shallow chalk[200]. Dislikes shallow clay soils and chalky soils[98, 182]. Requires a neutral to acid soil according to another report[202]. Prefers a rich loamy well-drained soil[98]. Succeeds in full sun or light shade[[188]. Plants can be trained to grow against a wall when they prefer a position in light shade[202]. Plants are very hardy, tolerating temperatures down to about -25¡c. but they are subject to damage by late frosts and are rarely successful away from the warmer counties of Britain[11, 200]. They require a long hot humid summer if they are to grow well, doing best in the east or south-east of Britain[182, 200] in areas that are not subject to late or early frosts. They do not generally do very well in the south-west, where the flower bracts are often damaged by frosts[200]. Medium to fast growing when young, but slowing with age[202]. Trees are short-lived[229]. A very ornamental plant, there are many named varieties[200, 202]. It is the state flower of Virginia[212]. Plants in this genus are notably resistant to honey fungus[200].
Eastern N. America – Maine to Florida, east to Kansas and Texas.
