I'm serious, it didn't produce much fruit but it just kept on growing. I built the raised garden in april of 2008 and I planted my first batch of vegetables once complete....this broccoli plant (a tiny transplant at the time) was included.
It grew a large 2 inch thick 2 foot high stalk. That stalk then split itself open and it started to grow new stalks nearly the same size. It kept repeating the process but this year those small green worms destroyed it. I then found other pests (nematodes/knotted roots) in the garden and figured this soil was done. So I resoiled the garden a month ago with new plants and so far so good.
btw the broccoli plant was still living when I yanked it out. The only original plant I have left from when the garden was built is a strawberry plant, and that only produces moldy strawberries.
