Will Brussel Sprout Plant Continue To Produce After Going To Blossom/seed?

Question

New to gardening and planted Brussel Sprout seedlings early last Spring (2020). They didn’t start growing at all till around mid-Summer after I threw some cut grass and old leaves in the raised bed with them – by the next day, no joke, they had grown a foot. By that time I’d given up on them knowing they were a cool season plant and just assumed they were bolting. Was caring for my Mom in her last days at that time and just forgot about them. The backyard wild bunnies feasted on them and only after they had eaten most of the crop is when I noticed they had actually produced a crop. Left them in place over the winter intending to clean out the raised bed this Spring. Plants were still green THIS spring and saw a couple new plants coming in around the old plants. Then the old plants really did bolt and sent out a bunch of flowers and mounds of seed pods. Was leaving them in place till the pods browned up to harvest the seed. Today however, I noticed the OLD plants ARE actually producing a new crop – lots of new little sprouts growing on the old stalk! Is this normal???!?!?? Just curious as this is my first experience with them… Thanks for your response!

Answer 1

They are biennial and usually flower in the second year. They normally do not produce a crop after flowering. Here is more:
