Quercus velutina Lam.

Black Oak is one of the most massive of the red oaks of eastern North America, but plays second fiddle to the better-known and more commonly cultivated Northern Red Oak (Quercus rubra). Though it is not as esteemed in ornamental terms as Q. rubra and Q. coccinea, it is a very decorative species, particularly in spring, when young leaves emerge densely covered in red velvety hairs, contrasting with the yellow staminate catkins, which according to Sternberg (2004) are ‘among the longest and most colourful and showy of the genus’. It is also distinguished by its very variable foliage: juvenile trees and lower branches of mature trees have shallowly lobed leaves, while deeply lobed ones occur on upper branches (Lance 2004). For Sargent (Sargent 1895), the narrow-lobed leaves on some individuals are very similar to Q. coccinea, but Q. velutina can be recognised in early spring ‘by the deep red color of the unfolding leaves and by its pale silvery appearance a few days later at the flowering period when Q. coccinea is bright green’. It has distinctive inner bark, which is yellow, unlike other Section Lobatae oaks that have pink to reddish-brown inner bark. François Michaux (1819) remarked that any remaining doubt about the identity of the species could be removed by chewing the inner bark, which is very bitter and stains saliva yellow, unlike other red oaks. The bark is rich in tannins and was once used for tanning leather; Native Americans used it medicinally to treat a wide range of ailments (Moerman 1986). It was also the source of a yellow dye.

Quercus velutina covers practically all the eastern half of the USA, except for portions of the coastal plain near the Gulf Coast and in southeast Georgia. The Great Lakes are the northern limit of its range, which extends across southern Ontario to Maine. It is one of the commonest species on the gravelly drift of southern New England and eastern states further south, and in the foothill regions of the southern Appalachian Mountains; it is also abundant in the Mississippi basin, probably growing to its largest size in the valley of the lower Ohio River (Sargent 1895). It is one of the most drought-resistant oaks, ranking close to Q. marilandica and Q. stellata, with which it is frequently associated on drought-prone sites. On better sites, it grows in association with Q. rubra and Q. alba. It will grow as cheerfully on sand dunes as in tight clay, and as a wild plant is found on a great variety of soils, though always more or less acidic. It is intolerant of shade and competition from other species, and more prone to structural damage and decay than Q. rubra; like that species, it is susceptible to oak wilt (Bretziella fagacearum) (Sternberg 2004). Young trees in dry sites will develop long tap roots, but not on better soils or sites (Miller & Lamb 1985). According to Sternberg it is extremely difficult to transplant, due in part to its long tap root, and it is recommended to grow it from seed in situ, or else transplant young seedlings promptly taking care not to disturb the root. It is sensitive to soil disturbance, and root control techniques are useful when growing seedlings for transplanting; cultivation in Air-Pot™ containers will increase the likelihood of success. Young trees have a tendency to develop a forked leader, which should be thinned and reduced to a central leader as soon as possible.

In habitat in the USA, the largest living specimen recorded is 36 m tall, with a trunk 262 cm in diameter, and grows near Virginia Beach City, Virginia. A tree with a thicker trunk grows in Hartford, Connecticut, 287 cm in diameter, but only 25.9 m tall (National Champion Tree Program 2025). Trees in cultivation tend to be smaller, the largest known may be found in Belgium: a tree in Arboretum Tervuren was 30 m × 91 cm dbh in 2021, and another at the Mariemont estate, Hainaut, had a trunk 165 cm in diameter in 2015, its height not recorded (Monumental Trees 2024). Living UK Champions are not as big, the tallest growing in Borde Hill, West Sussex (28 m × 69 cm) and the champion for girth growing in Albury Park Garden, Surrey. A larger tree, no longer in existence, was recorded at St Roche’s Arboretum in West Sussex, measuring 35.5 m × 123 cm in 1954, but this may be a misidentification (The Tree Register 2025). There is a legendary Q. velutina in the New York Botanical Garden, designated a Heritage Tree and billed as ‘one of the grandest trees’ in the garden. It is estimated to be over 200 years old, so would have been a century-old when the Botanical Garden was founded. In 2015 it was 31.7 m tall with a dbh of 149.6 cm and a canopy spread of 25.6 m (Cameron 2022).

Most references report 1800 as the date of introduction to European cultivation, citing the second edition of Hortus Kewensis, which states that it was introduced in that year by Messrs. Fraser (Aiton 1813). However, in the first edition (Aiton 1789), a species described as Quercus discolor, now a synonym of Q. velutina, is said to have been introduced in 1763 by Murdock Middleton. The second edition implies that this species is in fact Q. falcata, but Aiton gives for Q. discolor the common name ‘Downy-leav’d Oak Tree’, and it may have been what is now Q. velutina. According to Loudon (1838), André Michaux sent seeds of Q. velutina to France in 1786, but as no large specimens in France were known to Loudon, he assumed the plants raised by Michaux were probably lost during the French Revolution in 1789, when most of the plantations at Louis XVI’s Château de Rambouillet were destroyed. Despite its early introduction, it was not widely cultivated, especially in comparison to Q. rubra. According to Sargent (1895), the reason for its being rarely planted as an ornamental tree is that Q. velutina is ‘less stately than the Red Oak, and far less beautiful in foliage, especially in autumn, than the Scarlet Oak’. For Dirr (2009), it is ‘not an important tree in commerce’ but Dirr and Warren (2019) would later report that ‘in recent years, the species’ cultural attributes have caused nursery producers to become more accepting’. Though they report that it is not common in contemporary landscapes, they describe it as ‘a serviceable and utilitarian species’ and assert that ‘an open-grown black oak is a splendid experience’.

Black Oak was long valued as the source of quercitron, a natural dye derived from its inner yellow bark. It was discovered by Edward Bancroft in 1771 (one of only two natural dyes with a known discoverer), and he received a British patent controlling the distribution for twenty-eight years. The dye had a significant impact on the 19th century British calico printing industry, supplanting weld, a leading source of yellow for hundreds of years. Though succeeded by chome yellow, its use has persisted, and it is still available from dye suppliers for small-scale craft dyeing (Hansen 2011).

Quercus velutina was described by Lamarck in 1785. The epithet, which is Latin and means ‘velvety’, derives from vellus (= ‘fleece’) (Wiktionary 2025). Lamarck chose it in reference to the pubescence on the undersides of the leaves, which he described as veloutées ou comme drapes en dessous (‘velvety or as if draped underneath’). He called the oak Chêne velouté (‘velvety oak´). The winter buds are also pubescent, a convenient diagnostic feature, but this is not related to the epithet. Bartram (1791) called it Q. tinctoria (a name validated by André Michaux in 1801), in reference to the dye extracted from its bark (tinctoria = ‘of or pertaining to dyeing’). The common name Black Oak is likely due to the bark, which is very dark brown or black.
