The flowers are followed by small winged nuts that ripen in the summer and fall to the ground.

- Leaf spot: This fungal disease can cause brown or black spots to appear on the leaves. It can be prevented by providing good air circulation and avoiding overhead watering.
- Rust: This fungal disease can cause orange or yellow spots to appear on the leaves. It can be prevented by removing infected leaves and providing good air circulation.
