The Green Goliath below takes about 60 days. But I'd argue there's a big reason to grow broccoli that nobody discusses: it's a rock star of an edible teaching moment. The summer the photo below was taken we had a bunch of kids visit the roof. Without fail, seeing broccoli growing was the highlight of these visits.
"Really? It grows like this?" so many asked, as if we'd glued on the flowering stems.
My advice: grow broccoli in a SIP like we did below. Watch it thrive and watch kids get turned on to growing.

I'm trying something new this year: overplanting a SIP that's finished hosting its original veggie. Here's the broccoli Green Goliath (with my pal Trish)...
...harvested and re-seeded with Climbing Emperor beans. These we hope will climb the arches Art designed. I didn't add fertilizer, reckoning that there might be enough remaining.
