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.

  • Fill the remaining space with the potting soil but leave some space for future fertilizing.
  • Water the plant thoroughly until it drips out of the drainage hole, and place the pot or the hanging basket in a warm location.

Step 6: Germination Care

Follow the steps below to provide optimal care to the seeds during germination.

TemperatureMaintain the temperature around 68 to 86°F.
HumidityMaintain the humidity above 90%.
