Grafted Plant
Ziziphus jujuba 'Redlands'
Common Name: Redlands Jujube
Scientific Name: Ziziphus jujuba* 'Redlands'
Family: Rhamnaceae
Origin: Native to China, where it has been cultivated for over 4,000 years.
Description:
Ziziphus jujuba 'Redlands', commonly known as Redlands Jujube, is a deciduous fruit tree prized for its sweet, crisp fruits and its adaptability to various growing conditions. The tree typically reaches heights of 15-30 feet with a spreading, somewhat weeping form. It has glossy, dark green leaves that are oval and finely toothed, turning yellow in the fall. The branches are often thorny, making the tree somewhat difficult to handle without protection.
Flowers:
In late spring to early summer, the Redlands Jujube produces small, yellow-green flowers. These blooms are not particularly showy but are fragrant and attract a variety of pollinators.
Fruit:
The fruit of the Redlands Jujube is a small, oval drupe, typically about 1-2 inches in length. When ripe, the fruit turns a deep reddish-brown color and has a firm, apple-like texture. The flesh is sweet and crisp, making it popular for fresh eating, drying, or use in culinary dishes. The fruit is highly nutritious, rich in vitamin C, and has been traditionally used in Chinese medicine.
Growing Conditions:
Redlands Jujube is highly adaptable and can thrive in a wide range of soil types, including sandy, loamy, and clay soils, provided they are well-drained. It is drought-tolerant once established but will produce better yields with regular watering. The tree prefers full sun but can tolerate partial shade. It is also frost-hardy, capable of withstanding temperatures as low as -20°F (-29°C).
Uses:
Beyond its fruit, Redlands Jujube is valued for its ornamental qualities and can be used as a shade tree or in windbreaks. The fruit can be eaten fresh, dried, or processed into jujube tea, syrup, or candies. In traditional Chinese medicine, the fruit is used for its purported health benefits, including immune support and digestive health.
Care:
Redlands Jujube requires minimal maintenance once established. Pruning is recommended during dormancy to remove dead or crossing branches and to maintain an open canopy, which helps with air circulation and sunlight penetration. Fertilization needs are minimal; a balanced fertilizer applied in early spring can enhance growth and fruit production.
Pests and Diseases:
The Redlands Jujube is relatively pest and disease-resistant. Occasionally, it may suffer from pests such as aphids, spider mites, or scale insects, but these can usually be managed with horticultural oil or insecticidal soap. Diseases are rare, but good cultural practices, such as proper spacing and pruning, can prevent most issues.
Propagation:
Redlands Jujube is typically propagated by grafting onto rootstocks, which ensures the desired fruit characteristics and tree vigor. It can also be grown from seed, although seed-grown plants may not exhibit the same quality of fruit and may take longer to bear.
Overall, Ziziphus jujuba 'Redlands' is a versatile and resilient tree, well-suited for home orchards and landscapes where a combination of ornamental value and fruit production is desired.
