It is certainly true that when the two halves of the flower when

the strain of pea being grown may not be seed stable and even when
self pollinated will revert to something else. But most of the older
sweet peas can have the seed collected and you get exactly the same
thing the next year

Thanks for that! It was fascinating!!

O learning every day!
