Starfish Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: July 14, 2023

If you are an avid gardener looking to add a touch of uniqueness to your collection, starfish plant seeds may be just what you need. These fascinating seeds produce plants with leaves that resemble the shape of a starfish, hence their name. In this article, we will guide you through the process of storing, sowing, and germinating starfish plant seeds.

Storing Starfish Plant Seeds

Before you start sowing starfish plant seeds, it is essential to properly store them to ensure their viability. Here are some steps you can follow:

  1. Harvesting: Wait until the seed pods of the starfish plant turn brown and start to split open naturally. This indicates that the seeds are mature and ready for harvesting.
  2. Collecting: Gently collect the seed pods from the plant and place them in a clean container. Ensure that the pods are dry and free from any moisture.
  3. Drying: Allow the seed pods to air dry completely for about one to two weeks. Make sure to keep them in a cool, dry location away from direct sunlight.
  4. Extracting: Once the seed pods are fully dried, gently break them open to extract the seeds. Be careful not to damage or crush the seeds during this process.
  5. Cleaning: Remove any debris or chaff from the seeds by gently blowing on them or using a soft brush.

To store starfish plant seeds, you can use small envelopes or paper bags. Place the cleaned seeds inside the envelope or bag and label them with the date of collection and plant variety. Store them in a cool, dark place such as a refrigerator or a seed storage container at a temperature between 32-41°F (0-5°C). Properly stored starfish plant seeds can remain viable for up to three years.

Sowing Starfish Plant Seeds

Now that you have properly stored your starfish plant seeds, it’s time to sow them and start the germination process. Follow these steps for successful sowing:

  1. Timing: Starfish plant seeds are best sown in early spring when the weather is mild and the risk of frost has passed. Alternatively, you can sow them indoors during late winter and transplant the seedlings outdoors once the weather conditions are favorable.
  2. Soil Preparation: Prepare a well-draining potting mix by combining equal parts of peat moss, perlite, and vermiculite. Fill a seed tray or small pots with the potting mix, leaving some space at the top for watering.
  3. Sowing: Place one or two starfish plant seeds on top of the potting mix in each cell or pot. Gently press the seeds into the soil, ensuring they are in contact with the moist soil.
  4. Watering: Using a fine mist sprayer or a watering can with a gentle showerhead, water the soil until it is evenly moist but not soaking wet.
  5. Covering: To maintain humidity and promote germination, cover the seed tray or pots with a clear plastic dome or plastic wrap. This will create a mini greenhouse effect.
  6. Placement: Place the covered seed tray or pots in a warm location with indirect light. Avoid direct sunlight as it can cause excessive heat and dry out the soil.
  7. Germination: Starfish plant seeds usually take around 10-14 days to germinate. During this period, check the moisture level of the soil regularly and mist if necessary to keep it evenly moist.

Germinating Starfish Plant Seeds

Once your starfish plant seeds have germinated and sprouted, it’s important to provide them with the proper care to ensure healthy growth. Follow these guidelines:

  1. Lighting: After germination, move the seedlings to a location with bright, indirect light. A sunny windowsill or a fluorescent grow light placed about 6-8 inches above the seedlings will provide adequate light.
  2. Watering: Water the seedlings regularly, keeping the soil evenly moist but not waterlogged. Avoid overwatering, as it may cause root rot.
  3. Transplanting: When the seedlings have grown to about 2-3 inches in height and have developed a few sets of true leaves, they can be transplanted into individual pots or directly into the garden. Ensure that the soil in the new containers or garden bed is well-draining.
  4. Fertilizing: Once the seedlings are established, you can start fertilizing them with a balanced liquid fertilizer diluted to half strength. Apply the fertilizer every two weeks during the growing season.
  5. Hardening Off: Before planting them outdoors permanently, gradually acclimate the seedlings to outdoor conditions by exposing them to increasing periods of sunlight and wind over a week or two.

In conclusion, starfish plant seeds offer a unique addition to any gardener’s collection. By properly storing, sowing, and germinating these seeds, you can enjoy the beauty of starfish-like foliage in your garden. With a little patience and care, you will soon have thriving starfish plants that are sure to captivate anyone who sees them.

So go ahead and embark on this exciting journey of growing starfish plants from seeds. Happy gardening!
