Foxglove (Digitalis purpurea) is a beautiful perennial plant known for its tall spikes of tubular flowers. Collecting and storing its seeds properly can ensure successful planting in future seasons. Proper storage helps maintain seed viability and maximizes germination rates.
Gathering Foxglove Seeds
Seeds are typically harvested from mature foxglove plants in late summer to early fall. Look for seed pods that have turned brown and begun to dry out. Gently cut the seed heads and shake or rub them to release the seeds. Ensure the seeds are fully mature for the best results.
Preparing Seeds for Storage
After harvesting, spread the seeds on a paper towel or a screen to dry completely. This process may take several days. Proper drying prevents mold and rot during storage. Once fully dry, gently separate any remaining chaff or plant debris from the seeds.
Choosing the Right Storage Conditions
Foxglove seeds should be stored in a cool, dry, and dark place. Temperature fluctuations and humidity can reduce seed viability. Ideal storage conditions are around 40°F (4°C) with low humidity. Using airtight containers helps protect seeds from moisture and pests.
Recommended Storage Containers
- Glass jars with tight-fitting lids
- Sealed plastic bags with desiccants
- Seed storage envelopes kept in airtight containers
Labeling and Record Keeping
Always label your seed containers with the date of collection and the variety of foxglove. Keeping detailed records helps track seed age and viability, aiding in planning future plantings.
Storing Seeds Long-Term
For long-term storage, consider placing seeds in a refrigerator or freezer. Ensure they are in airtight containers to prevent moisture absorption. Regularly check stored seeds for signs of mold or deterioration, and rotate stock as needed.
Germination Tips
When ready to plant, soak seeds in water for 24 hours to improve germination. Sow in well-draining soil, covering lightly with soil. Maintain consistent moisture and temperature for optimal sprouting. Fresh seeds generally have higher germination rates, but well-stored seeds can remain viable for several years.
