The Dahoon Holly Tree, scientifically known as Ilex cassine, is a versatile and attractive evergreen tree native to the southeastern United States. Known for its glossy green leaves, bright red berries, and year-round appeal, the Dahoon Holly is a popular choice for adding beauty and wildlife interest to landscapes.
Dahoon Holly Tree Breakdown
Appearance:
The Dahoon Holly is characterized by its slender, upright growth habit and dense, dark green foliage.
The leaves are oval-shaped, glossy, and typically have smooth or slightly toothed edges. In the fall and winter, the tree produces clusters of small, bright red berries that persist into the winter, adding a splash of color and attracting birds. The tree's bark is smooth and grayish-brown, providing a subtle yet appealing contrast to the vibrant foliage and berries.
Growth Rate:
Moderate.
The Dahoon Holly grows steadily and can reach its mature height over several years, making it a manageable choice for a variety of landscape designs.
Size:
Typically grows to heights of 20-30 feet with a spread of 10-15 feet.
Its relatively narrow profile makes it suitable for small to medium-sized landscapes, as well as for use as a specimen tree or in mixed borders.
Sunlight Requirements:
Prefers full sun to partial shade.
The Dahoon Holly thrives in bright light, but it can also tolerate some shade, making it adaptable to different garden conditions.
Water Needs:
Requires regular watering, especially during its establishment period.
The Dahoon Holly prefers moist, well-drained soil and can tolerate occasional flooding, making it suitable for wetland areas or rain gardens. Once established, it is moderately drought-tolerant but benefits from consistent moisture.
Soil Preferences:
Thrives in well-draining, slightly acidic to neutral soils.
The Dahoon Holly is highly adaptable to a variety of soil types, including sandy, loamy, and clay soils. It can also tolerate wet, swampy conditions, making it a good choice for areas with poor drainage.
Maintenance:
Low.
The Dahoon Holly requires minimal pruning, typically just the removal of dead or damaged branches. It can be pruned to maintain a desired shape or size, especially when used as a hedge or screen. Fertilize annually with a balanced, slow-release fertilizer to support healthy growth and berry production.
Landscape Use:
Ideal for use as a specimen tree, in mixed borders, as a hedge, or as part of a wildlife garden.
Its attractive foliage and bright red berries make it a focal point in any landscape, and it provides food and shelter for birds and other wildlife. The Dahoon Holly is also suitable for use in rain gardens, wetland areas, and coastal landscapes due to its tolerance for wet conditions.

Hardy in USDA zones 7-10.
The Dahoon Holly prefers warm, humid climates and can tolerate light frost. It is well-suited to the southeastern United States and can thrive in both coastal and inland areas.
The Dahoon Holly Tree is a beautiful and versatile addition to any landscape, offering year-round interest with its glossy foliage, bright red berries, and attractive form. Its adaptability to a wide range of soil conditions, including wet areas, makes it a valuable choice for gardeners and landscapers looking to enhance their outdoor spaces.

Frequently Asked Questions
How to Plant & Care for Dahoon Holly Tree in Florida
Select a Stable Location
Choose a spot with full sun to partial sun and room for mature canopy growth. Avoid planting too close to structures.
Dig a Wide Hole
Dig 2–3x wider than the root ball but only as deep as the container. Trees should never be planted too deep.
Set Tree + Backfill
Place the tree level to slightly above grade. Backfill with native soil and firm gently to remove air pockets.

Water deeply right after planting, then daily for the first 1–2 weeks. Gradually taper as roots establish.

What Florida Customers Say
I was searching for a better plant source and after checking the internet, the consensus by most locals was to check out Dino's Palms. I have ordered multiple times and every plant I have gotten has been above expectations with health and fullness. The customer service is excellent! I am kind of blown away at how great this company is and will continue to use this as my main plant connection.
My experiences with Dinos have been wonderful. The communication about my orders & delivery was spot on, the deliveries guys quick, efficient and friendly - they even cleaned up fallen leaves from the driveway. But its the product that shined the most. Healthy, lush, vibrant. The same size posts as local nurseries - but the plants themselves were larger, fuller and more robust than anywhere we shopped. I cant say enough great things about their operations, their services and their products.
Dino's Palms did an amazing job with delivering and installation of my new calusia. Their plants are very affordable and I highly recommend them.
