Will sweet peas self seed?

Sweet peas are annual plants and will readily self-sow. The flowers go to seed if left uncut and form pods that vaguely resemble the pods of edible peas. While sweet peas are great attention-stealers, they can also complement some of the showier blooms in your garden.

Herein, do Sweet peas come true from seed?

“Yes, what Brian is saying is absolutely correct, sweet pea varieties will almost always come true from seed,” he confirms. The reason for this is that the sweet pea flower self-pollinates before it opens, so by the time any pollinating insects get to it, it's already too late.”

Secondly, how do you harvest and store sweet pea seeds? Bring the seedpods indoors and remove the seeds from the pods. Line a flat surface, such as a countertop or cookie sheet, with newspaper and let the seeds dry for about three days. Once dry, put them in a freezer bag or Mason jar with a tight-fitting lid to keep them dry. Store them in a cool place until planting time.

Correspondingly, do Sweet peas come back every year?

Sweet peas (Lathyrus odoratus) only live for a year, dying after setting seed. But don't let this put you off as they are super easy to grow from seed. Perennial species such as Lathyrus latifolius come back year after year, but mostly lack fragrance and there are fewer to choose from.

How do you prepare sweet pea seeds for planting?

You can sow them into pots of compost in autumn and overwinter the young plants in a cold frame or cool greenhouse. Or, you can wait until spring when you can sow into pots or directly into the ground. To prepare the seeds, leave them on moist kitchen roll until they swell or sprout.
