Sundrop Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: June 29, 2023

Are you looking to grow vibrant and stunning sundrop plants in your garden? Well, you’re in luck! Sundrops, also known as Oenothera, are beautiful flowering plants that can add a pop of color to any landscape. Whether you’re a seasoned gardener or just starting out, this guide will provide you with all the information you need to successfully store, sow, and germinate sundrop plant seeds.

Storing Sundrop Plant Seeds

Storing sundrop plant seeds properly is crucial to maintaining their viability. Here are some essential steps to follow:

  1. Harvesting: Wait until the sundrop flowers have faded and the seed pods have turned brown before harvesting the seeds. This is usually around late summer or early fall. Ensure that the seed pods are dry before collecting them.

  2. Cleaning: Remove the seed pods from the plant and place them in a paper bag or envelope. Gently shake the bag to separate the seeds from the pod.

  3. Drying: Spread the seeds out on a clean, dry surface such as a paper towel or a tray lined with parchment paper. Allow them to air dry for about a week in a cool, dark place.

  4. Storage container: Once completely dry, transfer the sundrop seeds into an airtight container such as a glass jar or a plastic bag. Make sure to label the container with the date of collection and the plant variety.

  5. Storage conditions: Store the container in a cool and dark location, such as a refrigerator or a basement. The ideal temperature for storing sundrop seeds is around 40 to 50 degrees Fahrenheit (4 to 10 degrees Celsius). Avoid exposing them to direct sunlight or extreme temperatures.

By following these steps, you can ensure that your sundrop plant seeds remain viable for future sowing.

Sowing Sundrop Plant Seeds

Now that you have properly stored sundrop plant seeds, it’s time to sow them and kickstart the germination process. Here’s a step-by-step guide to sowing sundrop seeds:

  1. Preparing the soil: Choose a sunny location in your garden with well-draining soil. Remove any weeds or debris from the area and loosen the soil with a garden fork or trowel.

  2. Sowing depth: Sundrop seeds are tiny, so they should be sown shallowly. Create small furrows or depressions in the soil, about 1/8 inch deep. Space the furrows about 12 inches apart to allow sufficient room for growth.

  3. Sowing method: Sprinkle the sundrop seeds along the furrows, aiming for about 3 to 4 seeds per inch. Avoid overcrowding the seeds as this can hinder their growth.

  4. Covering the seeds: Gently cover the seeds with a thin layer of soil or vermiculite. Press down lightly to ensure good seed-to-soil contact.

  5. Watering: Water the newly sown seeds gently, using a misting nozzle or a watering can with a fine spout. Ensure that the soil remains moist but not waterlogged throughout the germination period.

  6. Germination time: Sundrop seeds typically take around 7 to 14 days to germinate. During this time, it’s essential to provide consistent moisture and moderate temperatures for optimal growth.

Germinating Sundrop Plant Seeds

Once your sundrop plant seeds have been sown, it’s time to focus on their germination and subsequent growth. Here are some tips to help you successfully germinate sundrop plant seeds:

  1. Temperature: Sundrops thrive in warm temperatures between 65 and 75 degrees Fahrenheit (18 to 24 degrees Celsius). Maintain a consistent temperature by placing the pots or trays in a greenhouse or using a heating mat if necessary.

  2. Lighting: Sundrop seeds require sufficient sunlight to germinate and grow. Place the pots or trays in a location that receives at least 6 to 8 hours of direct sunlight each day. If natural light is limited, consider using grow lights to supplement the lighting.

  3. Watering: Monitor the moisture levels of the soil regularly and water as needed to keep it consistently moist but not waterlogged. Avoid overwatering as it can lead to root rot.

  4. Thinning: Once the sundrop seedlings have emerged and developed their first true leaves, thin them out to provide adequate spacing for growth. Remove the weaker seedlings, leaving only the strongest ones.

  5. Transplanting: When the seedlings have grown to about 2 to 3 inches tall, they can be transplanted into individual pots or directly into your garden. Ensure that the soil in the new location is well-draining and enriched with organic matter.

By following these guidelines, you’ll be able to successfully germinate sundrop plant seeds and watch them flourish into beautiful flowering plants.

In conclusion, growing sundrop plants from seeds can be a rewarding experience for any gardener. By properly storing, sowing, and germinating sundrop plant seeds, you can enjoy their vibrant blooms and add a touch of beauty to your garden. So go ahead and give it a try – happy gardening!
