Save money by collecting and storing seed of your favourite hardy annuals, to sow next year. Saving seed from pot marigold, Calendula officinalis, couldn’t be easier. Ensure you allow the seedheads to fully develop on the plant before collecting them (they will turn brown and papery as they mature), and store in a cool, dry place.
You Will Need
- Calendula seed
- Paper envelope
- Silica gel
- Airtight container
Step 1

When the seedheads have developed fully, remove them from the plant and lay them on a sheet of paper indoors, to dry for a few days. Once dry, separate the seeds from the seedhead. Place the seeds in a clean, labelled envelope.
Step 2

Place a sachet of silica gel in the container to prevent any moisture developing, and add the envelope of seeds. Seal the container and store it in a cool, dry place such as the fridge.
You can also save seed of cerinthe, nigella and poppy, for sowing in spring.
