Quercus laevis Walter

Though often maligned as a ‘scrub oak’ best suited for firewood, Quercus laevis has a small following of devoted fans. The distinctive leaf shape featuring svelte, elongated lobes, its brilliant red autumn colour, and its tenacity in overcoming the challenges of its inhospitable habitat are among the characteristics that earn this plucky oak its admirers. It revels in summer sunshine, to which it has adapted with some unusual heliotropic leaf behaviour; this is of little use in cultivation in temperate gardens, where it does not seem to prosper. The outline of the leaves, when they sport only three lobes, resembles a turkey’s foot, the reason for its vernacular name in the US, Turkey Oak. This leads to confusion with Q. cerris, which is commonly known as Turkey Oak in Europe, in reference to the west Asian country, one of many where it is found. Perhaps one should modernise this to Türkiye Oak, or distinguish Q. laevis as American Turkey Oak, but, as always, confusion can be avoided by shunning common names altogether.

In natural habitat, in the southeastern US, the greatest development of this species is in oak-pine forest with Pinus palustris and other scrub oaks like Quercus inopina, Q. marilandica, Q. margaretta, Q. geminata, Q. virginiana, and Q. myrtifolia, all species able to grow on droughty, infertile, and coarse soils. In these ecosystems, Q. laevis and other scrub oaks play a crucial role: were it not for their mast, deer and wild turkey would probably not survive the winter. The oak-pine forests in the dry sandy uplands of the Coastal Plain are rapidly being converted to pure pine by mechanical removal of all material and by planting improved pine stock capable of coping with the bleak conditions, despite the dire consequences for a range of biodiversity that has long been acknowledged (Miller & Lamb 1985). For now Q. laevis is listed as Least Concern by IUCN, but it could become Near Threatened due to the negative impact of predicted climate change (Wenzell, Kenny & Jerome 2017).

The leaves of this oak, unusually in the genus, hang with the blade perpendicular to the ground and parallel to the trunk. It is thought this limits the surface exposure to midday sunlight, thus reducing water loss through transpiration (le Hardÿ de Beaulieu & Lamant 2010), a behaviour that would be counterproductive when cultivated in temperate gardens. Sternberg (2004) observes that leaves of young seedlings orient north and south like a compass, presumably also responding to sunlight.

Loudon (1838) reports Quercus laevis was introduced to England in 1823, but does not say where or by whom, save that it was possibly growing in the Royal Botanic Garden Edinburgh. Le Hardÿ de Beaulieu and Lamant (2010) propose 1834 for its introduction to Europe, also without further detail. By 1910, Elwes and Henry declared it not to be in cultivation in England. It remains rare in collections: the Tree Register of Britain and Ireland (2025) lists only three, one of which is dead: a tree that reached 14 m × 26 cm dbh at Borde Hill, West Sussex, in 1995 and succumbed in 2015 (its identity may be questionable, as it was listed in the catalogue as ‘Q. catesbaei?’ and the size is large for the species in cultivation). The largest tree growing in Britain is at Chevithorne Barton, Devon, planted in 1992 and 3.5 m tall according to The Oaks of Chevithorne Barton (Heathcoat Amory 2009), but only 2.5 m tall in 2007 according to the Tree Register. Though happy at Chevithorne in a sheltered position, the species clearly does not do well in Britain which lacks the summer heat it needs to thrive (Heathcoat Amory 2009). In Europe, it is held in specialist collections in France (Arboretum des Pouyouleix, Arboretum de la Bergerette, Arboretum du Passadou), Spain (Iturraran Botanical Garden), and the Netherlands (Trompenburg Arboretum), but remains a rarity. In the US, it seems to have trouble surviving at the Arnold Arboretum, where several accessions have failed. A small plant, from wild-sourced seed collected in Alabama in 2015, has survived, reaching about 50 cm tall in 2021 (pers. obs. RC; Arnold Arboretum 2025). According to Sternberg (2004), it is barely hardy in USDA Zone 7, and it is ‘strictly a Coastal Plain tree’. The Hillier Manual (Edwards & Marshall 2019) gives it an H3 hardiness rating, tenderer than USDA Zone 7, which presumably reflects the plant’s need for sweltering summers.

For Sargent (1895), Quercus laevis has little to commend it as an ornamental tree, being rather ‘chiefly valuable from its ability to grow rapidly and produce good fuel on barren soil’. Loudon (1838) likewise suggested it stood out as an incinérant rather than as an ornament, noting that ‘it bears a higher price than that for any other oak in America for that purpose’. Nevertheless, it is popular with cognoscenti, though perhaps more in the wild than in cultivation: South Carolina nurseryman Bob McCartney singled it out as a favourite oak, common on his property ‘but regarded with contempt as ‘scrub oak’ by most neighbours’ (Russell 2014); John Grimshaw (pers. comm. 2025) likewise holds it to be a favourite, for its very distinctive leaves, great autumn colour, and its habitat; Hervé Mureau, landscape designer and botanist at Lyon Botanic Gardens, says he will never forget his ‘first encounter with an American oak species in the wild: Q. laevis with its pinkish young shoots just after bud break, in Ocala National Forest, Florida’ (pers. comm. 2025).

The species was for a long time known as Quercus catesbaei, a name published by Michaux in 1801, honouring Mark Catesby (1683–1749). Michaux cited Catesby’s illustration and description of ‘the Red Oak’ in The Natural History of Carolina, Florida, and the Bahamas Islands (1730), indicating that he had mistakenly referred it to Plukenet’s polynomial Quercus esculi divisura…, which corresponds to what Linnaeus called Q. rubra L. It was not until the early 20th century that it was determined that it had earlier been described as Q. laevis by Walter in 1788. Walter’s descriptions lack types, and his epithet laevis (‘smooth, hairless’) applies only to the upper surface of the leaves, as the lower surface is sometimes hairy. The name was widely accepted, however, and Ward neotypified it in 2008. It is not clear who first replaced Q. catesbaei with Q. laevis, but it is likely to have been Trelease, who used the name in his 1918 Winter Botany (in an article published in 1917, he still used Q. catesbaei).

The epithet laevis is Latin, but in classical Latin is considered an error, the correct form being levis, which means both ‘light’ (the root of ‘levity’) and ‘smooth’ (Lewis & Short 1879). Both meanings were gracefully combined in verse by Horace: fugit retro levis iuventas et decor (‘light [also: smooth, hairless, beardless] youth and beauty vanish behind us’) (Odes 2.11). In botany, it means ‘smooth, without hair’ rather than ‘light’, and ‘from the time of Linnaeus downward has been spelt botanically as ‘laevis’ (Jackson 1928). It has the same linguistic derivation as ancient Greek λεῖος (leîos), meaning ‘smooth’, as in leiocarpa (= ‘smooth fruits’) (Wiktionary 2025).
