How to Get String of Pearl Seeds?

The String of Pearl white flowers are extremely rare, so the flower heads must be pollinated to propagate them from seed.

After pollination, the flower head opens up as a big, light, fluffy ball that the wind can carry.

The seeds from unopened heads never germinate. However, the fluffy ones have a much better germination rate, and the seeds germinate quicker.

The String of Pearls produces seeds within the closed flower head. As the seeds mature, the flower stalk lengthens to provide a breeze for the seeds.
