Vegetables are having a major moment right now, and obscure vegetables even more so. We’re in an era where heading to your weekend farmers markets and subscribing to local community supported agriculture (CSA) shares are hip and trendy. Whether you are a vegetarian, flexitarian, full-on vegan or simply a vegetable lover, you’re going to want to scope out these 10 veggies. Get to know the following vegetables on a more intimate level -- how they taste, why they’re good for you, where to find them and ways to prepare them.

1 Kohlrabi

Sometimes known as a German turnip or turnip cabbage, kohlrabi is a bulb-like cruciferous vegetable that’s praised for its cancer-fighting properties. Both the vegetable and its leaves are edible and taste similar to the stalk of broccoli. Kohlrabi is delicious sliced thin and tossed in salads, steamed and mashed or roasted in wedge form for a low-carb potato alternative.

2 Celeriac

Celeriac, widely known as celery root, is a root vegetable with a knobby and gnarly appearance. It is edible both in raw and cooked forms, with a vibrant and distinctive celery flavor. Because of celeriac’s comforting quality, it often stars in soups, stews, casseroles, mashes and other savory dishes. For a fresh, raw take on the root vegetable, try shredding it and adding it to tossed salads, grating it onto roasted vegetables and lean meats or adding it to your favorite green juice. Celeriac is low in calories and high in flavor, making it a root-vegetable superstar.

3 Sweet Potato Greens

While sweet potatoes get a lot of love, their greens are all but overlooked. But these deep-green beauties are loaded with vitamin B-6, vitamin C and riboflavin. They have a velvety-soft texture and are less bitter and more pleasant that their competitors, kale and Swiss chard. Sweet potato leaves can be found at your local farmers market, in your CSA share or by simply asking a local farmer to save some for you. They are delicious raw or cooked. Try adding them to your green smoothie, cooked in a simple stir-fry or sauteed until just barely wilted and dressed with a little olive oil, sea salt and lemon juice.

4. Romanesco

4 Romanesco

Romanesco is some kind of magical lovechild between a cauliflower and broccoli. First documented in Italy, and also known as romanesco broccoli or roman cauliflower, this veg can now be found at your local farmers market during the fall months. This vegetable is striking in appearance, with its fractal, chartreuse peaks, and is crunchy and mild-tasting. Romanesco is rich in vitamin C, vitamin K and fiber. The best way to eat romanesco is to roast it.

5. Garlic Scapes

5 Garlic Scapes

Although garlic scapes are becoming more and more popular and widely coveted by the foodie and chef community, this less-than-conventional vegetable is still unknown to most. Garlic scapes (commonly shortened to just scapes) are the curly, shoot-like stalks growing from the bulb of the garlic plant. Scapes are harvested at the beginning of the growing season, typically late spring to the middle of summer, to direct more of the plant’s energy into developing the bulbs’ intense flavor. A popular way to prepare scapes is to blend them into a pungent pesto, but they’re also fantastic when treated like asparagus and grilled or roasted with a sprinkle of sea salt.

6. Purple Sweet Potatoes

6 Purple Sweet Potatoes

The purple sweet potato, also going by the name Stokes Purple, is in the morning glory family. It has a rich, deep flavor and can sometimes be slightly denser and drier than its orange cohort. What the purple sweet potato lacks in texture, it gains in its striking appearance. Purple sweet potatoes should be used in the same way that you’d use an orange sweet potato. And they’re starting to become regularly available at most conventional grocers. Purple sweet potatoes are loaded with antioxidants that are known to prevent cardiovascular disease, fight cancer, boost immunity and lower inflammation.

7. Sunchokes

7 Sunchokes

These hearty tubers are high in dietary fiber and have a mild, artichoke flavor. Something worth noting is that this vegetable is made of a carbohydrate called inulin, which the human digestive system has a harder time digesting. This can lead to flatulence if overconsumed. Sunchokes are wonderful blended into soups or added into vegetable mashes.

8. Fennel

8 Fennel

Fennel may be the least obscure vegetable on this list, but more often than not it can be intimidating to prepare. Both the fennel bulb and its fronds can be consumed raw or cooked, but the two have very distinct flavor profiles. Raw fennel tastes strongly of anise, while roasted fennel magically transforms in the oven and comes out with a mellow, celery-like vibe. Fennel is also harvested for its seeds, which are popularly used in Indian and Italian cuisine.

9 Fiddleheads

Fiddleheads, also known as fiddlehead ferns or fiddlehead greens, are the curled fronds of a young fern plant that are harvested as a vegetable. Fiddleheads, which have a short growing season, have a taste and texture similar to asparagus. You can find these rare treats at your local farmers market in the springtime. For perfection, wash your fiddleheads well and saute them gently in some ghee and garlic.

10. Cassava

10 Cassava

Cassava is an edible, starchy tuberous root that’s also known as yuca or yucca. It’s a drought-tolerant crop and a major food staple in the developing world that has recently gained more popularity in the United States. Cassava root has white flesh and thick, brown, waxy skin. The root itself contains residual amounts of cyanide and must be carefully prepared before consumption. Cassava flour is also becoming a popular gluten-free baking option.
