Gorgeous Upright Japanese Maple Varieties

A fast-growing tree, ‘Emperor 1’ bursts into spring with bold red foliage that remains vibrant throughout summer, offering a stunning contrast against the lush greens of other plants.

Known as the “lion’s head maple,” this is an old cultivar that thrives in hot climates. This tree showcases curled, contorted foliage that provides both visual interest and resilience, with golden-orange fall color that is consistent year after year. Its unique structure creates an eye-catching silhouette in the winter months, enhancing the seasonal appeal of the garden. ‘Shishigashira’ is less likely to suffer from leaf burn in full sun compared to other varieties, making it an excellent choice for sunny spots.

Dwarf Japanese Maples for Southern Gardens

Tips for Growing Japanese Maples in the Southeast
Here are some guidelines for growing Japanese Maples in the heat and humidity of the Southeastern United States:
1. Research cultivars for your specific growing conditions and choose wisely.
2. Don’t leave Japanese maples to their own devices; artful and carful pruning when trees are young will lead to better looking plants later. Removing dense interior growth can additionally improve the air movement through the trees. This can deter fungal disease.
3. Watch out for reflective heat. Reflective surfaces like bright white siding, glass, or stones that retain heat can lead to leaf or root burn of Japanese maples.
4. Don’t plant too deeply. Ensure you can clearly see the root flare on trees; don’t be afraid to plant slightly above grade.
5. Check roots at the time of planting. It is not unusual for containerized plants to have root defects, including girdling roots. Correct these at planting time.
6. Water regularly until establishment. Once established, you can prevent some leaf-burn by giving plants supplemental water during prolonged dry spells.
Growing Japanese maples in the Southeast can be a deeply rewarding experience, allowing gardeners to enjoy the beauty and diversity of these remarkable trees. When incorporating Japanese maples into your garden design, consider their unique forms, colors, and growth habits. By choosing the right cultivars and providing the proper care, you can create a stunning landscape filled with color and elegance, ensuring that your Japanese maples thrive in the Southern heat and humidity. Embrace these captivating trees and watch your garden transform into a serene oasis of beauty and tranquility.
