Seven Top Turnip (Brassica rapa “Seven Top”), have an incomparable sweet flavor when harvested when nighttime temperatures remain 40° F and below. The colder temperatures promote sweetness in the leaves. Although, some do prefer the slight bitterness that develops when the turnip greens mature a bit longer. You may be able to harvest the turnip root, but you must do so when it’s very young. Otherwise, they are considered inedible.

Seven Top Turnip is a cool-weather biennial but is grown as an annual in much colder regions, usually over the winter for a spring harvest. In zones 9-10, Seven Top can be grown and harvested throughout the winter. Allow the plants some partial shade to avoid bitterness in the leaves.

Growing indoors is possible. However, managing temperature may be difficult. Consider a porch garden where you can move the plants indoors or outdoors, depending on temperatures and weather conditions.
