ABOUT

Commonly known as the holly olive, this plant is characterized by its glossy, rich green leaves. These leaves are distinctly spiky, resembling those of a holly plant, which is where it gets one of its common names. Over time, the leaves may become less prickly as the plant matures. The holly olive is evergreen, maintaining its foliage throughout the year. During the blooming season, the plant produces small, white, inconspicuous flowers that emit a sweet, fragrant scent, which can add a pleasant aroma to the area where it's planted. Following the flowering period, the holly olive may also produce small, blue-black berries, which can attract birds and other wildlife. The overall appearance of the holly olive is dense and bushy, making it a popular choice for hedges and privacy screens in gardens. Its ability to be pruned into various shapes also makes it a favorite for formal and topiary gardens. The leathery texture of the leaves along with their spikiness gives the plant a robust look that can provide contrast in a landscape setting.

Pruning
  • water dropWater

    False Holly should be watered thoroughly, allowing the soil to dry slightly between waterings. Typically, you should provide water every 7 to 10 days, using about 1 gallon for outdoor plants, depending on weather conditions and soil drainage. For potted plants, adjust the amount of water based on the pot size, usually between 8 to 16 ounces. Over-watering can lead to root rot, so ensure good drainage and decrease watering frequency during cooler months.

  • sunLight

    False Holly prefers full sun to partial shade. It thrives in a location that receives at least 4 to 6 hours of direct sunlight daily but is also tolerant of light shade. Too much shade can result in fewer flowers and a less dense habit. A spot that offers morning sunlight with some afternoon shade is ideal, especially in hotter climates.

  • thermometerTemperature

    False Holly can tolerate a range of temperatures and is hardy from USDA zones 7 to 9. It can survive minimum temperatures of around 0 to 10 degrees Fahrenheit and maximum temperatures as high as 100 degrees Fahrenheit. However, the ideal temperature range for this plant is between 60 and 80 degrees Fahrenheit. False Holly can be damaged by temperatures below 0 degrees Fahrenheit without proper protection.

  • scissorsPruning

    Pruning False Holly helps maintain its shape, encourage bushier growth, and remove any dead or damaged branches. Prune in late winter or early spring before new growth begins. This can be done annually, but the plant can also be pruned every other year if desired. The best time to prune extensively is during its dormant period to minimize stress on the plant.

  • broomCleaning

    As needed

  • bambooSoil

    False Holly thrives in well-draining, fertile soil with a slightly acidic to neutral pH of 6.0-7.5. A good mix can be made with equal parts garden loam, peat moss, and sharp sand or perlite to facilitate drainage.

  • plantRepotting

    False Holly should be repotted every 2-3 years or when root bound, ideally during spring before the onset of the growing season.

  • water dropsHumidity & Misting

    False Holly prefers average room humidity levels; it's adaptable but thrives when humidity is above 40%.

  • pinSuitable locations

    • Indoor

      Ensure bright indirect light, avoid dry heat sources, and maintain moderate humidity.

    • Outdoor

      Plant in partial shade, shelter from harsh winds, mulch, and ensure soil is well-draining.

  • circleLife cycle

    The life of Osmanthus heterophyllus, commonly known as holly osmanthus or false holly, begins with seed germination, which is enhanced by cold stratification and occurs in moist, well-drained soil. Following germination, the seedling stage involves the development of primary leaves and a root system. As the plant enters the juvenile phase, it develops the characteristic spiny leaves, resembling those of a holly, and undergoes vegetative growth, increasing in size and leaf mass. This evergreen shrub may take several years to reach maturity, at which point it begins to produce fragrant white flowers in the late summer through fall, signaling its reproductive phase. Pollination by insects leads to the production of small, blue-black fruits (drupes), which are then dispersed by birds and other animals, thus completing the cycle. The mature plant can enjoy a long lifespan, sometimes living and growing for several decades, provided it is in a suitable environment with adequate care.

      Spring to summer

    • The most popular method of propagation for the False Holly (Osmanthus heterophyllus) involves semi-hardwood cuttings. This typically takes place during the late summer. To carry out this method, a grower would select healthy stems of the current year’s growth. The cuttings should be about 4 to 6 inches (10 to 15 centimeters) long, with the leaves removed from the lower half. The base of the cutting is then dipped in rooting hormone to encourage growth and placed in a well-draining potting mix. The cuttings are kept under high humidity and indirect light until they have rooted, which may take several weeks. Regular misting and a consistent temperature can help improve the success rate of rooting.
