Turnips are a fast-growing, cool-season root crop that matures in 6-10 weeks. Both the root and the nutritious leafy tops (turnip greens) are edible. They are easier and faster than swedes, making them a better choice for warmer Australian zones where swedes struggle. An underrated vegetable that deserves a place in every winter garden.
