The winter season in South Australia is known as one of the coldest seasons of the year, with an average temperature of 16-22 degrees Celsius daily.

Hardy vegetables include spinach, sweet corn, cabbage, Brussels, kale, broccoli, rabi, leek, garlic, mustard, radish tara beans, corn salad, sprouts, and turnip.
Semi Hardy vegetables thrive in winter but only do well in light frost without damage. Semi-hardy vegetables include Swiss chard, radish, lettuce, celery, parsley, endive, and parsnips.
Although cabbage, swiss chard, and lettuce must be covered with row covers or frost blankets if the temperatures go below the freezing point for a long time.
Other winter vegetables to grow include sweet potatoes, silverbeet, fennel, Jerusalem artichoke, and kale.

Carrots are a good source of beta-carotene converted to vitamin A. Vit A is good for vision, proper growth, development, and immunity. Carrots are also loaded with carotenoids, an antioxidant.
This antioxidant helps to protect against chronic diseases such as cancer(prostate and breast cancer), high blood pressure, heart disease, and stroke.
10. Brussels Sprouts
