Low maintenance. Propagation: Scarifying seeds. Do this by gently rubbing the seeds with sandpaper or carefully nicking them with a knife. Soak the scarified seeds in warm water for 24 to 48 hours to soften them. Plant the seeds in a well-draining potting mix, covering them with a thin layer of soil. Maintain a consistent temperature of around 70 to 75°F (21 to 24°C) and provide indirect light. Keep the soil consistently moist but not waterlogged. Germination may take several weeks to a few months. Once the seedlings have grown large enough to handle, transplant them into individual pots or your desired garden location.
