Cornus elliptica (Pojark.) Q.Y.Xiang & Boufford

Cornus elliptica is one of a number of evergreen ‘strawberry-fruited’ dogwoods that occur across East Asia, distinguished by its small white inflorescences held on elongated peduncles above the glossy green foliage. Seen out of flower, the more leathery leaf with glossier upper surface and more roughly textured trichomes beneath, and the globose (not compressed) fruits distinguish the species from C. capitata, and the exposed buds and evergreen leaves contrast with those of C. kousa – both species within which it has been included in the past. The distributions of all three taxa overlap in Eastern China, but chemical analysis (of cambial peroxidase isozymes – a useful indiator of molecular variation within closely related taxa) had indicated, even before the availability of molecular data, that C. elliptica is distinct from either of those species (Dudley & Santamour 1994). However, the relationships and circumscriptions of all of the members of subgen. Syncarpea remain poorly understood, and the taxonomic picture continues to evolve. Several recent studies have found C. elliptica to be nested within C. hongkongensis (Du et al. 2023; Du, Cheng & Xiang 2024; Guan et al. 2024), a finding that is unsurprising, at least based on the similarity of leaf characters and the mainly eastern Chinese distribution. Where the two species are grown together in cultivation, flowering in C. elliptica is a few weeks later than C. capitata (M. Wenzel, pers. comm. 2026).

The species was first introduced to the United States by Ted Dudley from western Hubei, collected by the 1980 Sino-American Botanical Expedition from the famous Metasequoia valley in Lichuan Xian (SABE 2032 – accessioned to the US National Arboretum as NA 49163). Dudley treated these plants as C. angustata (unaware that that name was already in use for a fossil taxon), subsequently reduced to a subspecies of C. capitata by Xiang (1987). Other introductions include Allen Coombes’ 2004 collection (CMBS 880) from Hunan at 1200 m asl, and Barry Clarke’s 2004 Hunanese collection BWC 17 (at the Hillier Gardens). SICH 1862, found in a number of arboreta, was collected in Sichuan in 1996 at 1520 m asl. Under C. elliptica (NA 60792–L) the US National Arboretum also grows material from a mixed collection originally received in 1989 from F. W. Schumacher Co., made just south of 31°N latitude in Jiangxi Province at 1300–3150 m asl – this plant has narrow elliptic to elliptic-ovate leaves, and broad-elliptic to almost suborbiculate white bracts; the leaf undersides are pale glaucous grey-green, but the upper leaf surface is deep matt green rather than glossy (US National Arboretum Plant Finder 2026).

Cornus elliptica is hardier than the older Himalayan introductions of C. capitata (though more recent Chinese introductions of that species show a significantly expanded hardiness envelope). Hogan (2008) records plants having survived temperatures of –12ºC without serious damage in the Pacific Northwest, where they thrive in dappled shade and moist conditions. As Dirr (2009) notes, the typical form of the species is not evergreen in regions where winter temperatures fall below –18°C (USDA Zone 6). Even in temperate climates where leaves are retained, the foliage takes on an unusual winter hue, regrettably (but accurately) characterised by Dirr as ‘puke purple-green’. Selections that retain the green colouring in the leaves at lower temperatures include ‘First Choice’, from the J.C.Raulston Arboretum. Anomalous autumnal flowering was noted on SABE 2032 material growing at the US National Arboretum in 1998, triggered by cool weather at the beginning of October following a long hot summer (NCSU Herbarium 1998).

Many plants in cultivation as Cornus elliptica do not fully accord with the description in Flora of China, which characterises the leaves as typically ‘grayish-green on both surfaces, densely pubescent with white appressed trichomes, scabrous, rarely tomentose’. The leaves of cultivated C. elliptica vary in the density of the pubescence, and in some selections (e.g. ‘First Choice’) are more-or-less glabrous abaxially. The Flora also separates C. capitata from C. elliptica by the purported absence of pit-domatia in the latter species; again, some plants cultivated as C. elliptica have pit domatia.
