Quick Answer
To collect seeds from heirloom flowers, allow the flowers to dry and turn brown, then remove the seeds from the seed head, and separate them from any debris. Use a small, sharp tool to extract the seeds from the seed pods. Store the seeds in a cool, dry place to preserve their viability.
Choosing the Right Moment for Seed Collection
Collecting seeds at the right moment is crucial for their viability. Wait for the seed pods to dry completely, which is usually indicated by a change in color and a crunchy texture. For example, sunflower seeds are ready when the flower head has turned a light brown and the petals have dropped off. Dandelion seeds are ready when the seed head has turned a dark brown and the seeds are easily detached from the stem. Typically, this occurs within 1-2 weeks after the flowers have bloomed.
Extracting Seeds from Seed Pods
Once the seed pods are dry, use a small, sharp tool, such as a pair of tweezers or a seed extractor, to extract the seeds. Be careful not to damage the seeds or the surrounding tissue. For seed pods that are difficult to open, such as those of the morning glory, use a sharp knife to carefully slice along the edge of the pod and release the seeds. Handle the seeds gently to avoid bruising or damaging them.
Storing and Preserving Seeds
After extracting the seeds, store them in a cool, dry place to preserve their viability. Store the seeds in a paper envelope or a small glass container with a lid, and label them with the seed name and date. Store the seeds in a cool, dry location, such as a basement or a cupboard, and keep them away from direct sunlight and moisture. For long-term storage, consider storing the seeds in a vacuum-sealed container or a desiccant bag to maintain a stable environment and prevent degradation.
