Ilex opaca x atenuata ‘Savannah’
Description: This is a hybrid between the American holly and the dahoon holly. This broadleaf evergreen tree has a narrow, pyramidal to columnar shape. A mature tree can reach a height of up to 35 feet with a width of approximately eight feet after 40 years of growth. Its upright, slender form makes it suitable for tight spaces. The tree has a moderate growth rate, meaning it establishes itself gradually over time but can eventually reach impressive heights if left unpruned.
Twig/Bark: The current year’s twigs will be medium in thickness and green in color. The bark is smooth and gray in color. It’s thin and can be easily damaged by mechanical impact.
Leaves: Its leaves are pale green, spiny, and thinner than those of other holly trees.
Flower/Fruit: The flowers are small and unobtrusive, ranging from pale green to white, and bloom in the spring. In the fall, the tree produces abundant clusters of bright red berries that persist through the winter. The round, fleshy, red berries, less than ½ inch in length, appear in heavy clusters in the fall and last through the winter. While decorative, the berries are toxic and should not be consumed.
Habitat: This tree thrives in acidic, medium-moisture, well-drained soils and does best in full sun to part shade. It is relatively low-maintenance as long as its soil and moisture needs are met.
