Thanks Carolyn. I figured my chances for harvesting any were slim to none. The seeds were from an SSE seed rack at a local nursery, and the brocolli seeds I also bought and started at the same time did just fine. I'll probably harvest the last of the smaller side heads this week. Now that I know how long brussel sprouts really take, I'll make sure I get them going a lot earlier next year. If I'm successful, they will be included in next year's thanksgiving menu!
