Quercus pagoda Raf.

Cherrybark Oak was for a long time in the taxonomic shadow of Quercus falcata, a species it easily surpasses in dimensions and growth rate, and from which it can be distinguished by its bark and the shape of its leaves, which feature a V-shaped base, as compared to the U-shaped base of Q. falcata, and regular straight lobes, unlike the falcate, curved lobes of Q. falcata. The epithet pagoda refers to the outline of the leaf: when hung vertically from the petiole, the outline resembles the roof of a pagoda.

Quercus pagoda is typically found in fertile soil in moist lowlands, including alluvial bottomlands, terraces of swamps, riverbanks and mesic slopes (Lance 2004). Though it grows best in moist, well-drained bottomland sites, it adapts to drier sites in full sun or partial shade (North Carolina Co-operative Extension 2021), though according to Miller and Lamb (1985) it will not do well in full shade. It is a tall, massive tree, usually with a straight, columnar trunk in the wild, and is possibly the most valuable oak for timber production in the American South. It grows fast, both in habitat and in cultivation, and also makes an attractive landscape tree (Sternberg 2004). Le Hardÿ de Beaulieu & Lamant (2010) commend it as ‘superb’ when dressed in light hues in springtime and brilliant shades of orange to purplish-red in autumn.

A date of introduction of 1904 is given by Krüssman (1978) and quoted by Grimshaw and Bayton (2009), but this seems suspect, given that Elwes and Henry wrote in 1910 of this oak (as Q. falcata var. pagodæfolia): ‘Specimens were gathered by Elwes in 1904 at Mt. Carmel, Illinois; but the tree has not yet been introduced’. Perhaps Krüssman misinterpreted this statement. The earliest documented introduction in the UK is a 1921 accession at Royal Botanic Gardens, Kew, received from the Arnold Arboretum, Massachusetts, USA. According to Clarke (1988), it was planted in 1930 and had reached 21.3 m × 51 cm dbh in 1979. This tree seems to have been overlooked in past UK rankings, as a tree across the River Thames at Syon Park was referred to as the champion in cultivation by Heathcoat Amory (2009) and Grimshaw and Bayton (2009). The Syon Park tree measured 24 m × 98 cm in 2022, while the one at Kew reached 25.5 m × 102 cm in 2023. According to the Tree Register (2025), the tree was previously labelled as aff. falcata; Clarke (1988), however, identifies it as Q. falcata var. pagodifolia. Trees in natural habitat easily trump these dimensions: the US champion, growing in an urban setting in Portsmouth City, Virginia, measured 35.7 m × 247 cm in 2018 (National Champion Tree Program 2025). Dirr (2009) reports seeing trees in the Oconee River floodplain (Green Co. and Oconee Co., Georgia) easily 25 to 30 m tall, with long, slender boles rising 12 to 15 m without a single branch.

Grimshaw and Bayton in 2009 were surprised that it was not better known in European collections. That lacuna has since been filled, and it is now found in the principal collections in Europe, as well as in several parks and gardens in the UK, as well as in specialised oak collections.

According to Miller and Lamb (1985), it reaches ages of ninety to one hundred and twenty years in vigorous condition, and its branch-free bole makes it a valued industrial product; when grown with space to spread its limbs, it forms a well-shaped crown and is popular as a shade tree in the lower Mississippi Valley. In cultivation, it is widely reported to grow fast and with good form, maintaining a central leader (Dirr 2009), growing as much as 9 m in a decade (Dirr & Warren 2019). A tree at Sir Harold Hillier Gardens, Hampshire, UK, grown from seed collected in Missouri in 1986, reached 21 m × 53 cm in 2023 (The Tree Register 2025). The tallest trees in ex-situ cultivation seem to be found in New Zealand, grown from seed possibly collected in Mississippi, sourced through the Forest Research Institute in Rotorua. Five trees grow at Hackfalls Arboretum, New Zealand, accessioned in 1973. Their dbh was just under 1 m in 2020, and a height of 25.9 m is recorded for one of them, also in 2020 (Hackfalls Arboretum 2025). Another four trees grow at Eastwoodhill Arboretum, the National Arboretum of New Zealand, the largest of which was planted in 1975 and measured 31.8 m × 110 cm in 2025 (M. Kleiters, pers. comm.).

Cherrybark Oak is susceptible to oak wilt (Bretziella fagacearum) and wood-boring insects. Hispidus canker (Polyporus hispidus) is common on this species, and heart rot in standing trees is found on poor sites (North Carolina Co-operative Extension 2025).

Quercus pagoda was first described in 1824 as a variety of Q. falcata by Elliott, who stated that it had a strong affinity to that species, but ‘may deserve further examination.’ He had first seen it in North and South Carolina. He called the variety pagodæfolia, but did not explain the derivation. Rafinesque raised Elliott’s variety to species status in 1838, and though he cited Elliott’s name as a basionym, he changed the epithet to pagoda, mentioning ‘lobes gradually lessening in size so as to resemble a pagoda’. Ashe respected Elliott’s epithet in 1897, when he published Q. pagodæfolia, apparently not aware of Rafinesque’s name, which has priority. Grimshaw and Bayton (2009) suggest that the epithet reflects the tapering, pagoda-like shape of the young tree, but this seems an unlikely derivation and is not mentioned in the protologues.
