According to Wikipedia:
Broccoli is an edible green plant in the cabbage family (Brassicas) whose large flowering head and stalk is eaten as a vegetable. The word broccoli comes from the Italian plural of broccolo, which means “the flowering crest of a cabbage”, and is the diminutive form of brocco, meaning “small nail” or “sprout”.
Broccoli is classified in the Italica cultivar group of the species Brassica oleracea. Broccoli has large flower heads, usually dark green in color, arranged in a tree-like structure branching out from a thick, edible stalk which is usually light green. The mass of flower heads is surrounded by leaves. Broccoli resembles cauliflower, which is a different cultivar group of the same Brassica species. Combined in 2016, China and India produced 73% of the world’s broccoli and cauliflower crops.
This source gives the following reason too:
Cauliflower and broccoli that have velvety surfaces are not consumed by orthodox Jains. Very tiny flee like flying insects that grow in and around the farms, get stuck on to their velvety surfaces, and can not be fully removed in spite of careful washing.
Unfortunately now a days, loads of pesticide is used to kill insects and pests. While there is a likelihood of finding some of these pests in broccoli but they are largely pest free. Also washing then carefully with separated florets does the trick. Now the question arises of ‘sachit’ bhojan … to harvest them, farmer needs to cut of the plant when it is still alive. I am not sure if there is still life in broccoli which we get in market.
