Juglans ailantifolia var. cordiformis seed
LATIN NAME: JUGLANS AILANTIFOLIA VAR. CORDIFORMIS
COMMON NAME: Heartnut, Heart-shaped Walnut
The Juglans ailantifolia var. cordiformis, or heartnut, is one of the most distinctive and useful of the walnuts, and its compound, bright-green leaves, its spreading habit and its heart-shaped, edible nuts which are easy to crack have made it a favourite of the nut orchards and the large gardens across the temperate world. It grows as a medium-sized, deciduous tree of the walnut family, reaching up to fifteen metres or more, with the spreading, rounded crown bearing alternate, compound, bright-green leaves with the many oval, toothed leaflets, and bearing, in the spring, the male catkins and the female flowers, followed by the clusters of the green, husked nuts which contain the heart-shaped, edible, easy-to-crack nuts inside. It is a variety of the Japanese walnut, native to the regions of the East, while it has been cultivated in the nut orchards and the large gardens for its edible nuts, and it is known as the heartnut or the heart-shaped walnut.
Scientific Research & Plant Biotechnology
The heartnut has a real and distinguished place in research. It has been studied in the horticulture and the nut science, since the Juglans ailantifolia var. cordiformis is a popular, easy-to-crack nut tree for the orchard and the large garden, and the researchers and the breeders have examined its many forms, its breeding and its cultivation, while the study of the walnuts and the nut trees has drawn attention in the international horticultural and agricultural press. The plant has also been studied in the genetics and the plant science, since the heartnut is a variety of the Japanese walnut and a relative of the other walnuts, and the researchers have examined its genetics, its traits and its use in the breeding, while the study of the walnut genetics has been of continuing interest. The species has also been studied in the food science and the nutrition, since the heartnut is an edible nut with a distinctive, heart-shaped kernel, and the researchers have examined its composition, its nutrition and its uses, while the compound, bright-green leaves and the heart-shaped nuts of the heartnut have been of interest to the botanists and the growers. For a nut of such distinction, the Juglans ailantifolia var. cordiformis has a rich and distinguished record of research.
Ecological & Economic Value & Wide Applications
To grow the Heartnut from seed, the heartnut is a medium-sized, deciduous tree of the temperate regions, bearing the compound, bright-green leaves and the clusters of the green, husked nuts in the autumn. Its nuts are a food for the squirrels and the other wildlife, and its spreading, rounded crown gives a fine shade in the large garden and the orchard, while its edible, easy-to-crack nuts are a favourite treat in the autumn. Its economic value is real: the heartnut is prized as an easy-to-crack, edible nut tree for the orchard and the large garden, and its value has drawn attention in the international horticultural and food press, while the distinctive, heart-shaped nuts and the easy cultivation have made it a favourite of the nut orchards and the large gardens, and the tree is a fine addition to the orchard, the large garden and the woodland. To raise the heartnut, sow the nuts in pots of moist, open soil in a cool, bright place, keep them gently watered, and grow the little trees on in the sun.

During the summer, the tree produces small, yellowish-green flowers that develop into edible nuts in the fall. These nuts are encased in a green husk, which, when peeled, reveals a wrinkled, edible seed.
The bark of Juglans ailantifolia var. cordiformis is dark gray to brown, and its wood is known for its strength and grain pattern, which makes it highly sought after in woodworking.
Ecological Role and Habitat Native to the temperate forests of East Asia, Juglans ailantifolia var. cordiformis thrives in well-drained, loamy soils, typically in forested areas and along riversides. It requires a moderate climate and does best in areas with a distinct winter period, which helps to regulate its dormancy cycle. This walnut variety can be found growing in a variety of habitats, including both natural forests and cultivated landscapes, where it provides shade and adds to the biodiversity of the region. The tree is relatively drought-tolerant once established, but it prefers regular rainfall during its growing season.
