Notes: Japanese Maples are highly prized for their beautiful foliage and delicate structure. While they thrive in temperate climates, they can be challenging in hot climates like Central Texas. In such regions, choosing the right variety and providing some afternoon shade is key to success.

Varieties for Central Texas:

1. 'Bloodgood' – Known for its vibrant red leaves in spring, summer, and fall. A more heat-tolerant variety, it’s a popular choice for Central Texas, providing reliable color and structure.

2. 'Emperor 1' – Another red-leaf variety that has good heat tolerance. It offers stunning red foliage in all seasons and is more adaptable to Central Texas’ climate than many other Japanese Maples.

3. 'Sango Kaku' (Coral Bark Maple) – Features green leaves with a soft, golden-yellow fall color. Known for its striking red bark in winter, it’s relatively more heat-tolerant and performs well with some afternoon shade.

4. 'Shishigashira' (Lion's Head Maple) – A compact variety with a unique, dense, and rounded shape. Its deep green leaves turn yellow or orange in fall. It performs well in partial shade in Central Texas.

5. 'Green Cascade' – A weeping variety that has soft green foliage. It tolerates heat and sun but benefits from some afternoon shade in Central Texas to avoid leaf burn.

These varieties are more adaptable to the heat and sun conditions of Central Texas. However, they should still be protected from the hottest afternoon sun to ensure the best health and vibrant foliage.
