Sweet peas or lathyrus odoratus come in all colors except yellow. Breeders such as Keith Hammett have created, and keep creating, different cultivars for us to enjoy. There are even sweet peas that change color as they age!

How do you harvest sweet pea seeds?

If you leave your sweet pea flowers on the vine, then you will notice that they start to develop pods. These pods will grow the seeds for the next generation of plants. The seeds will be ready to harvest when they seed inside the pod starts to rattle (sounds like a baby's rattle) inside the pod. At that point, simply cut the pod off the vine and place it in a dry paper bag and fold over the top. Usually the pod will burst open on it's own and you will find your sweet pea seeds in the bottom of the bag. If the pod doesn't pop open by itself, simply tear it open with your fingers and remove the seeds. Pods left on the vine 'spring' open to distribute their seeds onto the ground, so don't wait too long to harvest that seed!

Do sweet peas cross pollinate?

Sweet peas are self-pollinating - they fertilize themselves whilst the flower buds are still young and haven't opened.
