I totally missed you said broccolini. With gardening you can learn something new every day. I googled broccolini and also looked but I don’t see that they grow a main head. Check out Google images for broccolini. Some pictures show the perfect cutting size. They look just like broccoli. A few pictures showed spindly older stalks. I watch mine every day. On the broccoli, if the head gets wider and there is a hint of a yellow flower it is almost late.
We are on the road today. I don’t know what variety of broccolini I got, so will have to check the tag tomorrow. It was $5 for the starter at Walmart. Looked healthy so I just grabbed it to try. I have one or two sunny spots just off the front brick walkway, so I will likely plant it there. Hubby says not to worry about the HOA. We voted out the last group that were overbearing, and there are fewer violation letters being sent these days, which is very welcome. I hate HOAs, but I love this house and property even so.
