Broccoli rabe, also spelled raab, isn't a true broccoli despite the name. It's a leafier, faster, more pungent brassica grown for its young leaves, stems, and small flower buds all together, with a distinctly bitter, mustardy edge closer to a turnip green than standard broccoli.

Good companions

Radish: Radish (including the daikon form) is a documented trap crop for flea beetles, which prefer its mustard oils over other brassicas and can be sacrificed or pulled once infested: the same research cited on the radish page. This is exactly the pest its own placement note already flags as hitting the crop hard.

Where to buy broccoli rabe seeds

Varieties we recommend, and where to get them:

'Spring Raab' broccoli rabe (best for season-long planting): Johnny's Selected Seeds describes this as the most versatile broccoli raab for growing throughout the season, a hybrid alternative to De Cicco where a longer sowing window matters more than heirloom status.
