Yes, you can, but it may be a bit challenging.

Absolutely! You can propagate it with its seeds. I've got a few tips that you'll find helpful.

2. Use a sharp knife to scratch the seed coat, or use sandpaper slowly. You're doing great!
3. Sprinkle the seeds on a planting medium that has good drainage. You're almost there!
4. Maintain humidity and place the pot in a warm, sunny location. You're doing a great job!
