How to Harvest
- 1Harvest lupine seeds when the pods turn brown and begin to dry but before they split open.

- 3To avoid harming the plant, handle it gently and avoid pulling or tugging on the stems.
Step 5
Saving Seeds
How to Save Seeds
Saving seeds from your Lupine plant is easy and rewarding! Once the flowers have faded, let the seed pods dry on the plant until they turn brown and start to rattle—this means the seeds are ready. Gently collect the pods before they burst open, then pop them open to release the seeds. Let the seeds dry for a few days in a cool, dry place, then store them in a labeled envelope or jar in a cool, dark spot until you’re ready to plant next season. You’ve got this—saving seeds is a simple way to keep your garden growing year after year!
