Sensitivity Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: July 4, 2023

If you are a fan of unique and interesting plants, then the sensitivity plant (Mimosa pudica) should definitely be on your list. Also known as the touch-me-not or the shame plant, this tropical perennial is famous for its fascinating response to touch. When touched or exposed to certain stimuli, its leaves fold inward and droop, giving it a shy and sensitive appearance.

To grow your own sensitivity plants, you will need to start with good quality seeds. In this article, we will guide you through the process of storing, sowing, and germinating sensitivity plant seeds to ensure successful growth.

Storing Sensitivity Plant Seeds

Before sowing your sensitivity plant seeds, it is important to store them properly to maintain their viability. Here are some key steps to follow:

  1. Harvesting: Start by allowing some of the flowers on your existing sensitivity plant to wither and dry out naturally. Once the flowers have dried completely, carefully pluck them off the plant.

  2. Extracting Seeds: Open up the dried flowers gently and you will find small black seeds inside. Collect these seeds in a clean container.

  3. Drying: To ensure longevity, allow the seeds to dry completely before storing them. Spread them out on a paper towel or a clean surface and leave them in a well-ventilated area for about a week. Make sure they are not exposed to direct sunlight or high humidity.

  4. Storage Container: Once the seeds are fully dried, transfer them to an airtight container such as a glass jar or a resealable plastic bag. It is important to choose a container that can prevent moisture from entering and damaging the seeds.

  5. Labeling: Don’t forget to label your storage container with the date of collection and any other relevant information such as the plant species or variety. This will help you keep track of the seeds’ viability and age.

  6. Ideal Storage Conditions: For long-term storage, place the container in a cool, dark, and dry location. A refrigerator or a cool basement are good options. The ideal temperature for storing sensitivity plant seeds is around 40°F (4°C).

By following these steps, you can ensure that your sensitivity plant seeds remain viable for up to 2-3 years.

Sowing Sensitivity Plant Seeds

Once you are ready to sow your stored sensitivity plant seeds, here’s what you need to do:

  1. Soil Preparation: Choose a well-draining potting mix that is rich in organic matter. Avoid heavy clay soils as they tend to retain excess moisture, which can lead to root rot.

  2. Container Selection: Select a shallow container with drainage holes to prevent waterlogging. Alternatively, you can use individual seed trays or biodegradable pots.

  3. Sowing Depth: Sow the sensitivity plant seeds on the soil surface and gently press them down. Avoid burying them too deep as they require light for germination.

  4. Watering: Moisten the soil lightly using a spray bottle or a watering can with a fine rose attachment. Be careful not to oversaturate the soil, as it can hinder germination.

  5. Germination Time: Sensitivity plant seeds usually germinate within 1-2 weeks, but it can take up to a month in some cases. Keep the soil consistently moist but not waterlogged during this period.

  6. Temperature and Light: Place the sown container in a warm location with temperatures around 70-75°F (21-24°C). Provide indirect sunlight or fluorescent lighting for at least 12-14 hours a day.

  7. Transplanting: Once the seedlings have developed their second set of true leaves, they are ready for transplantation into individual pots or a larger container.

Germination Tips and Troubleshooting

Here are some additional tips to help you with the germination process:

  • Scarification: If you experience poor germination rates, you can scarify the seeds by lightly scratching the outer seed coat with sandpaper or a nail file. This will help water penetrate the hard seed coat and promote faster germination.

  • Soaking: Soaking the seeds in warm water overnight before sowing can also enhance germination rates.

  • Moisture Control: Avoid overwatering during the germination process, as it can lead to fungal diseases or damping-off.

  • Temperature Variations: Sensitivity plant seeds thrive in warm temperatures, but providing a slight temperature drop at night (around 10°F or 5°C) can sometimes trigger better germination.

With proper care and attention to detail, you can enjoy the captivating beauty of sensitivity plants in your own garden. From storing the seeds to sowing and germination, following these guidelines will help you achieve successful growth and ensure a thriving sensitivity plant population. Happy gardening!
