The seeds have a hard seed coat that has to be treated, or scarified, in order for water to enter the seeds so that they can sprout.
- Scarify the seeds by nicking or sanding the seed coat.
- Soak the seeds in water for several hours.
- The seeds like moist, well-drained soil. Prepare a mixture of half potting soil and half sand, perlite or vermiculite. Put the soil in a pot. Water the mixture so that it is moist but not wet.
- Put the seeds on the soil.
- Cover the seeds with a thin layer of soil.
- Water the seeds.
- Place the pots in an area with warm temperatures in full sun or part shade. The seeds take several weeks to germinate.
- When the seedlings are a few inches tall, they can be transplanted.
