Celtis julianae Schneid seed

LATIN NAME: CELTIS JULIANAE

COMMON NAME: Julian’s Hackberry, Chinese Hackberry

The Celtis julianae, or Julian’s hackberry, is a tough and useful tree of the warm woodlands, and its oval, toothed leaves and its small, orange-brown fruits have made it a valuable tree for the landscape and the urban planting across the warm and the temperate regions. It grows as a deciduous tree of the hemp family, reaching up to twenty metres or more, with a smooth, grey bark and the spreading, rounded crown, bearing alternate, oval, toothed, bright-green leaves with the unequal bases, and bearing, in the spring, the small, greenish flowers, followed by the small, round, orange-brown, sweet fruits on the long stalks in the autumn. It is a species of the flowering tree, native to the warm woodlands of the East, while it has been cultivated for its toughness and its shade, and it is known as the Julian’s hackberry or the Chinese hackberry.

Scientific Research & Plant Biotechnology

The Julian’s hackberry has a real and distinguished place in research. It has been studied in the forestry and the urban forestry, since the hackberries are tough, drought-tolerant trees which are valuable for the urban planting and the erosion control, and the researchers have examined their growth, their tolerance of the difficult conditions and their value in the landscape, while the study of the tough landscape trees has drawn attention in the international forestry and horticultural press. The plant has also been studied in the horticulture and the ornamental-plant science, since the Celtis julianae is a graceful, shade-giving tree for the warm garden and the park, and the researchers have examined its cultivation, its propagation and its value in the landscape, while the study of the deciduous shade trees has been of continuing interest. The species has also been studied in botany, since it is a member of the hemp family and a relative of the other hackberries, the hops and the cannabis, and its relationships, its distribution and its many forms have been examined, while the oval leaves and the orange-brown fruits of the Celtis julianae have been of interest to the botanists and the foresters. For a tree of such toughness, the Julian’s hackberry has a rich and distinguished record of research.

Ecological & Economic Value & Wide Applications

To grow the Julian’s Hackberry from seed, the Julian’s hackberry is a deciduous tree of the warm woodlands, bearing the oval, toothed leaves and the small, round, orange-brown fruits in the autumn. Its sweet fruits are a favourite food of the birds and the small animals, and its spreading, rounded crown gives a fine shade and a shelter in the garden and the park, while its tolerance of the drought and the poor soil makes it a valuable tree for the difficult sites. Its economic value is real: the Celtis julianae is prized as a tough, shade-giving tree for the urban landscape and the park, and its value has drawn attention in the international forestry and horticultural press, while the graceful habit and the easy cultivation have made it a favourite of the warm-region landscapes, and the tree is a fine addition to the park, the large garden and the street planting. To raise the Julian’s hackberry, sow the seeds in pots of moist, open soil in a bright, cool place, keep them gently watered, and grow the little trees on in the sun.

Celtis julianae Schneid seed (Julian Hackberry)

Celtis julianae, Julian hackberry, is a large‑growing deciduous tree originating across central‑southern China. Smooth pale‑grey bark, thick textured ovate leaves and warm golden‑orange autumn drupes give it notable landscape appeal. This hardy tree tolerates urban pollution, wind exposure and varied soil conditions, making it well‑suited for city street planting, slope stabilisation, park‑tree schemes and native‑forest restoration. Bird wildlife feeds on its seasonal fruits, adding ecological value to planted sites. Seed‑raised saplings preserve natural population diversity for nursery output and habitat rehabilitation work.

Working with seed brings practical horticultural benefits for this hackberry species. Seed‑originated trees develop deep anchoring taproot systems that deliver excellent wind‑firmness and adaptability to poor or compacted field soils. Large‑scale seed sowing allows nurseries to produce substantial numbers of saplings for broad‑scale greening projects. Genetically diverse seed batches yield robust young trees well‑adjusted to shifts in seasonal temperature and rainfall across temperate growing zones.

Fleshy drupes ripen through September‑October. Harvest ripe fruits, macerate and wash away soft outer pulp to retrieve firm brown seeds. Clean seed is air‑dried in shaded ventilated spaces. A sustained moist‑cold stratification period replicates natural winter woodland conditions, fully preparing internal embryos for vigorous, even growth once temperatures rise in spring.

Prepared seeds go into open nursery seed‑beds filled with deep, loamy, well‑drained substrate. Bury seeds under moderate light soil cover. Full sun or gentle dappled light suits early‑stage development. Maintain steady mild moisture within seed beds, while strictly avoiding stagnant water around seed tissues. Under favourable spring nursery conditions, strong, well‑formed seedlings emerge steadily above ground level.

Young hackberry seedlings expand their characteristic pubescent ovate foliage and make steady yearly height gains. Balanced watering and periodic light feeding support coordinated root and shoot development. Saplings respond well to routine nursery tending and transplant smoothly during dormant seasons. As seed‑grown trees mature year after year, they build broad rounded crowns. Mature specimens produce seasonal fruit crops that feed local bird populations, bringing long‑term ornamental, environmental and wildlife‑supporting function to urban and restored woodland landscapes.

Trees, to 30 m tall, deciduous. Bark gray. Branchlets dark brown, densely brownish yellow pubescent, rarely glabrous. Winter buds brown, 1-4 mm; scales at least inner ones brownish red hispid with appressed, parallel hairs. Petiole 0.7-1.5 cm, robust, densely golden pubescent, adaxially with a deep and narrow furrow; leaf blade broadly ovate to narrowly ovate-elliptic, 6-13 × 3.5-8 cm, thickly papery, abaxially densely golden pubescent or rarely so only on veins, adaxially smooth or scabrous, base ± rounded and slightly oblique, margin finely toothed above middle to rarely subentire, teeth 13-23 on each side and less than 1 mm, apex shortly acuminate to caudate-acuminate; secondary veins 4-6 on each side of midvein. Flowers densely fascicled. Style branches linear, undivided. Infructescence solitary, stout, unbranched, densely brownish yellow pubescent, rarely glabrous, 1-3 cm, 1.5-2.5 × as long as subtending petiole. Drupe 1 per infructescence, golden to orange-yellow, ellipsoid to ± globose, 1.1-1.4 cm. Stone milky white, obovate to broadly obovate, compressed slightly on both sides, 7-9 mm, reticulately foveolate, base acute to slightly obtuse, 2-ribbed on apical half. Fl. Mar-Apr, fr. Sep-Oct. Plants with glabrous twigs and infructescences have been called var. calvescens. They do not seem to differ from the species in any other way.
