Ilex crenata 'Convexa', commonly known as Japanese holly, is a versatile evergreen shrub that brings year-round interest to gardens with its glossy green foliage and compact growth habit. A favorite among gardeners for its adaptability and elegance, this cultivar is well-suited for creating formal borders, group plantings, or serving as a stately solitary presence. Moreover, its ability to thrive in a variety of light conditions and soil types makes it an excellent choice for hedging in diverse landscapes.

With its charming white flowers blooming in the early summer months and glossy black berries appearing in autumn, Ilex crenata 'Convexa' adds a touch of classical beauty to any garden setting, blending seamlessly with a range of plant companions.

Key Features

Ilex crenata 'Convexa' is a highly adaptable evergreen that maintains its rich green foliage throughout the year.
The shrub's growth form is upright to bushy, reaching an ultimate height of around 80 cm, which makes it ideal for small to medium-sized garden spaces.
Its evergreen nature ensures that it provides a constant backdrop of green, even in the winter months when other plants have lost their leaves.
Although it requires average water needs, this Japanese holly is not drought-resistant, and thus regular watering should be part of its care.
Minimal pruning is needed to maintain its shape, allowing for a low-maintenance addition to any landscape.

Tips

For optimal growth of Ilex crenata 'Convexa', plant it in well-drained soil and provide it with an average amount of water to keep the soil moist, but not waterlogged.
While the Japanese holly can tolerate shade, placing it in an area with full sun to partial shade will promote the best flowering and berry production.
Propagation can be done through semi-ripe or hardwood cuttings, with the latter typically being taken from autumn to winter.
When pruning, do so sparingly to maintain the plant's natural shape and density, ensuring that it continues to provide visual interest throughout the year.

Ideal placement of a Ilex crenata 'Convexa'

Ilex crenata 'Convexa' thrives in a variety of locations, from full sun to partial shade and even in shaded areas, showcasing its versatility. For optimal growth, the soil should be well-drained, accommodating the plant's average water needs. Although it is adaptable to different soil types, ensuring good drainage is key to maintaining a healthy root system. This shrub's remarkable adaptability makes it suitable for a range of garden designs, whether as a border, grouped planting, or a solitary feature. Moreover, its evergreen foliage retains its lustrous cream, yellow, and green hues throughout the year, contributing to the garden's visual appeal in all seasons.

How do I plant a Ilex crenata 'Convexa'?

For successful establishment in the landscape, this evergreen shrub should be planted in a hole twice as wide as the pot and of the same depth. This allows the root system to spread out and anchor itself within a well-draining medium, adaptable to a variety of soil types. It thrives under full sun to complete shade, making it remarkably versatile for garden design. Once planted, maintain consistent moisture levels around the roots, especially during the critical first year, to ensure the plant becomes well-established and resilient. Regular watering supports steady growth, allowing it to reach its mature height of 80 cm with a lush, upright to bushy appearance.

Pruning a Ilex crenata 'Convexa'

Maintaining the elegant form of Ilex crenata 'Convexa' requires minimal pruning. This versatile shrub thrives with its natural bushy habit, and excessive cutting is often unnecessary. Should you desire to shape or reduce its size, the optimal time for pruning is late spring, after the blooming period to ensure the plant's energy is focused on recovery and new growth. It is essential to use clean, sharp tools to make precise cuts, which help preserve the health and appearance of the evergreen foliage.

Watering a Ilex crenata 'Convexa'

To maintain the health and vigor of Ilex crenata 'Convexa', ensure that the soil remains evenly moist. While it has average water requirements, consistency is key. During periods of extended dryness or heat, additional irrigation may be necessary to supplement natural rainfall. Conversely, during cooler, wetter seasons, reduce watering to prevent waterlogging, as well-drained soil is essential for this species. Young plants, in particular, benefit from regular watering as they establish their root systems. Established specimens are more tolerant and require less frequent attention, yet monitoring soil moisture remains advisable.

Fertilising a Ilex crenata 'Convexa'

To ensure the Ilex crenata 'Convexa' thrives, a balanced approach to fertilization is recommended. This species benefits from being fertilized once in early spring as new growth begins, and again in late summer to prepare it for the colder months. Utilize a controlled-release fertilizer formulated for evergreen shrubs, which will provide a steady supply of nutrients over several months.

When applying fertilizer, distribute it evenly around the base of the shrub, avoiding direct contact with the foliage and stems to prevent burn. This consistent nourishment supports the plant's upright to bushy growth habit and maintains the vibrant cream, yellow, and green foliage throughout the year. Moreover, the added nutrients can enhance the white blooms in spring and summer, as well as the development of the black fruit in autumn.

Ilex crenata 'Convexa' thrives in well-drained soil, so ensure the potting medium allows for adequate drainage to promote healthy root development.
