- Leaves: The leaves are star-shaped and turn a beautiful red or orange color in the autumn.
- Roots: The roots develop deeply and robustly.

Propagation Methods
- Seeds: Seed propagation is not common due to a low germination rate.

- Cuttings: Propagation via cuttings is also possible, but the success rate is low.

Cultivation Methods
- Soil: It prefers well-drained soil and can adapt to acidic to neutral soils.
- Sunlight: It grows optimally in sunny locations. - Water: It has deep roots, so once it grows well, its water requirements are low. However, sufficient water supply is necessary during the initial stages.

Uses in the Garden
'Slender Silhouette' thrives even in confined spaces, making it suitable for small urban gardens or street landscaping. Its beautiful form and vibrant autumn foliage make it highly visually appealing.

Important Pests and Control Methods
