Seeds from sweet peas fell off when plant flowers died in the fall, will these seeds take root, this year?

My dead sweetpea stems are still on my treliss. It is spring now, is it too late to cut them back? I was told they were annuals, but they were up when we moved in 2 years ago, and came up again last year. The seeds from the pods, fell onto the ground when flowers died. Will those seeds take roots and grow this year ?

If you have had a mild winter you may get some self setters. The best thing to do is harvest the seed in fall, keep them frost free and dry throught the winter, then plant them in 3'' pots in spring. You can then plant them where you like without transplanting.
Reply:yep --they probably will--are you talking bout edible sweet peas --English peas to some people--or the vine called sweet peas that is inedible--if its the former--they maybe immature seeds and will not come up-- if they are the flowering kind they will do what nature meant for them to do and replenish their self
Reply:quite likely. Nasturtiums do this as well. Planted some 5 yrs ago,they seed themselves every year and give me free plants. The autumn frosts kill off the plants but I find the seeds germinate all through the winter
