What Exactly Is a Mustard Tree?

You’ve probably heard of mustard as a condiment, but did you know there’s an actual mustard tree? Yep! The term "mustard tree" typically refers to plants in the Brassica or Sinapis family—most commonly the Sinapis alba (white/yellow mustard) or Brassica juncea (brown/black mustard).

Despite its name, the mustard tree isn’t really a tree in the traditional sense. It’s more like a tall bush that can grow up to 6–9 feet high under ideal conditions. But don’t let that confuse you—it packs a punch in both flavor and utility.

  • Watering: Keep soil moist but not soggy
