American holly

Ilex opaca 'Mamie Eisenhower'

American holly, or Ilex opaca 'Mamie Eisenhower', is an evergreen conical shrub valued for its foliage and large, bright red berries. It's a small, slow-growing tree, reaching up to 15 feet in height. Although it can be cultivated as a container plant, it is best grown in a sunny spot in the ground. In spring, small white flowers appear on the plant before being replaced by colorful red berries which last through the winter season. The plant has broad, shiny green leaves with stout spines along the edges. This native North American species is an excellent choice for a landscape hedge or windbreak.

watering

American holly (Ilex opaca 'Mamie Eisenhower') should be watered deeply and consistently, using about 1 inch of water per week. Keep the soil lightly moist at all times but avoid overwatering. During the summer months, when the plant is actively growing, it is recommended to raise the amount of water to 1.5 inches per week. In cooler months, and particularly in the winter, the amount of water can be reduced.

sunlight

American holly (Ilex opaca 'Mamie Eisenhower') thrives in sunny locations, but it is important to provide some shade during the hottest part of the day to avoid damage to the foliage. This species prefers 6-8 hours of direct sun daily, ideally morning sun with afternoon shade. It is also important to give this plant adequate air circulation, so avoid planting it too close to buildings or other structures.

pruning

American holly (Ilex opaca 'Mamie Eisenhower') should be pruned annually in late winter or early spring. Be sure to prune out any damaged or dead branches first. Then, select branches that are growing badly, too close together, or too far away from the main canopy. Prune back 1/4 to 1/3 of the longer branches, and thin out densely-clustered shoots. Bear in mind that pruning should be done with caution, as American holly is a slow-growing species. Doing too much pruning at once can stunt the growth of the plant.
