Japanese Cornel Cherry Cornus officinalis
ABOUT
Cornus officinalis, commonly known as Japanese cornel or Cornellian cherry, is a deciduous shrub or small tree that boasts a multitude of appealing features throughout the seasons. In late winter to early spring, before the foliage emerges, it comes alive with small yellow flowers that cover the branches, providing a bright and cheery display. These flowers are structured in dense clusters and are particularly attractive against the backdrop of the late winter landscape. As the flowering season concludes, the plant springs forth oval-shaped leaves, which start off with a glossy green color and later develop into purplish-red shades come fall. The leaves are opposite in arrangement and have visible veins that give them a texture, adding depth to their appearance. Following the flowering season, berry-like fruits appear, initially bright red and gradually maturing to a darker, blackish hue as the season progresses. These fruits are small and oval, adding another layer of visual interest and appeal to the plant. The bark of Japanese cornel is rough and exfoliating, with a mix of gray and brown tones that lends the plant a rugged and rustic character. Overall, Japanese cornel is a plant with a kaleidoscope of features that change and evolve throughout the year, providing lasting appeal for any garden or naturalized setting. Its compact form, brilliant flowers, attractive foliage, summer fruits, and textured bark make it a multifaceted addition to the landscape.

- Water
The Japanese Cornel, or Cornus officinalis, requires regular watering to maintain moist but not waterlogged soil. During the growing season, it is recommended to water the plant deeply once a week, providing about 1.5 gallons for medium-sized shrubs. Adjust the frequency of watering during periods of extreme heat or drought, possibly increasing to twice per week. In winter, reduce watering to match the plantβs reduced requirements due to dormancy. Always check the first couple of inches of soil for dryness before watering to avoid overwatering.
- Light
The Japanese Cornel thrives best in full sun to partial shade. Planting it in a location that receives at least 4 to 6 hours of direct sunlight daily is ideal to promote healthy growth and flowering. However, it can also tolerate some shade, especially in hotter climates where afternoon shade can help protect the plant from excessive heat.
- Temperature
The Japanese Cornel is hardy and can survive in temperatures ranging from 5 to 90 degrees Fahrenheit. The ideal growing temperature for optimal health and flowering is between 60 and 75 degrees Fahrenheit. Avoid placing the plant in areas where winter temperatures drop below 5 degrees Fahrenheit, as extreme cold can damage the plant.
- Pruning
Pruning the Japanese Cornel is mainly done to maintain its shape and remove any dead or diseased wood, enhancing the plant's health and appearance. Prune in late winter or early spring before the new growth starts. Thin out overcrowded branches and cut back any that are crossing or rubbing against each other. This should be done annually or as needed to keep the shrub well-groomed.
- Cleaning
As needed
- Soil
Cornelian cherry (Cornus officinalis) thrives best in well-draining soil with a pH range of 5.5 to 7.5. A balanced mix of loamy soil, peat, and sand or perlite would provide the necessary drainage and nutrients. It is important to ensure the mix does not retain excess water, which can lead to root rot.
- Repotting
Cornelian cherry plants typically do not need to be repotted frequently. Younger plants can be repotted every two to three years, while mature plants can go longer without repotting unless they show signs of being root-bound or the soil has degraded.
- Humidity & Misting
The cornelian cherry prefers moderate humidity levels, around 40-60%. It can tolerate some level of dryness, but consistent humidity close to the ideal range will assist in optimal growth and health of the plant.
- Suitable locations
Indoor
Provide bright light, keep soil moist, and ensure good air flow.
Outdoor
Plant in well-draining soil, full sun to partial shade.
Hardiness zone
5-8 USDA
- Life cycle
Cornus officinalis, commonly known as Japanese cornelian cherry, begins its life cycle as a seed which needs to undergo a period of cold stratification to break dormancy. Upon germination in early spring, the seedling emerges and establishes a root system while producing its first leaves. The plant then enters a vegetative growth phase where it grows steadily, developing a woody stem and branches. After a few years of growth, it reaches maturity and starts producing small yellow flowers in late winter to early spring before the leaves emerge. Following pollination, usually by bees, it sets fruit which is a bright red drupe that matures by late summer to autumn. The plant continues to grow and reproduce annually, with some specimens capable of living for decades under optimal conditions.
- Propogation
Propogation time
Spring through Summer
For the Cornus officinalis, commonly known as Japanese cornel or cornelian cherry, the most popular method of propagation is through seed. Propagation time typically begins in autumn after the fruit has ripened. To propagate by seed, one should first extract the seeds from the ripe berries, then clean and dry them. Stratification is often required, which involves chilling the seeds for a period of 90-120 days in moist sand or peat at a temperature of 33-41 degrees Fahrenheit (0.5-5 degrees Celsius), to break the seed dormancy. After stratification, seeds should be sown in a well-draining soil mix at a depth of about twice the diameter of the seed. Germination can be slow and irregular. Once seedlings emerge and reach a suitable size, they can be potted on or planted out into their final location.
