You probably know beet as that rich red root staining your cutting board or swirling into salads. But there’s much more to this vibrant veggie than meets the eye. Beet is a multitalented plant—nutrient-rich, incredibly adaptable, and rooted in centuries of cultural and culinary tradition.
In this Plant Compendium entry, we’ll dig into all things beet: where it comes from, how to grow it, and why it’s worth a spot in your garden or plate. Whether you’re a curious gardener, a health-conscious cook, or just beet-curious, this post is for you. Let’s get into it!
History of Beet
Beets have been cultivated for thousands of years, originally prized more for their greens than their roots. The wild ancestor of modern beets grew along the Mediterranean coast. Ancient civilizations like the Egyptians and Greeks used beet leaves as food and medicine.
By the Roman era, people began cultivating beets for their roots, although they looked very different from today’s plump globes. The modern sweet beetroot really took off in 18th-century Europe, especially after scientists figured out how to extract sugar from it—leading to the rise of sugar beets.
Today, beet comes in several varieties: red, golden, white, and even striped!
Botanical Description
Beet (Beta vulgaris) is a hardy biennial plant typically grown as an annual. It’s part of the same species family as Swiss chard, and both share similar leaves and growing habits.
Roots: This is the main event—the edible root is round or cylindrical, firm, and colored red, golden, or white depending on variety. Red beets get their color from betalains, a group of antioxidants responsible for those deep jewel tones (and the occasional pink-stained fingers).
Stems: The stems, called petioles, are strong and colorful—often red or green. They’re edible too!
Leaves: The leafy tops (beet greens) grow in a rosette and resemble chard. They’re bright green with red, pink, or golden veins and are rich in nutrients.
Flowers: In their second year (if left unharvested), beets produce tall flower stalks with small, greenish flowers—not especially showy, but essential for seed production.
Seeds: Each seed "cluster" is actually a group of seeds fused together. These corky, irregularly-shaped seeds germinate into multiple seedlings unless thinned.
Growing Instructions
Beets are cool-weather champs and pretty easy to grow once you know the basics.
Sunlight: Full sun is best, but beets can tolerate light shade—especially in hot climates.
Soil: Loose, well-draining soil is key. Heavy clay can cause misshapen roots. Aim for pH 6.0–7.5.
Temperature: Ideal growing temps are 10–21 °C (50–70 °F). Beets can handle light frost, but high heat can slow root development.
Watering: Keep soil evenly moist. Dry spells can lead to woody roots or split skins. Mulch helps hold moisture.
Spacing: Thin seedlings to 7–10 cm (3–4 in) apart. Crowded beets compete for space and develop poorly.
Pruning: Remove yellowing leaves, but don’t harvest too many greens from a single plant—it can slow root growth.
Life Cycle:
Germination: 5–14 days, depending on temperature.
Vegetative Growth: About 6–8 weeks to reach harvest size.
Bolting (second year): In mild winters, unharvested beets may flower in spring.
Harvesting and Foraging
Harvesting
Roots: Ready when 3–7 cm (1–3 in) across. Pull gently or loosen with a fork to avoid damaging the skin.
Leaves: Pick young leaves anytime. Use scissors to harvest the outer leaves and let the inner ones keep growing.
Foraging
Wild beets (like Beta vulgaris subsp. maritima) are rare in most regions. If foraging, stick to coastal or saline environments—and always triple-check your plant ID.
Plant Companions
Beets play nicely with many plants, but not all neighbors are friendly.
Good companions:
Onions, garlic, and leeks – natural pest repellents.
Bush beans and lettuce – minimal competition and different root depths.
Avoid near:
Pole beans – may inhibit beet root growth.
Mustard family plants – can stunt each other’s development.
Common Pests and Diseases
Beets are hardy, but here’s what to watch out for:
Leaf miners: Tunnel through leaves, leaving trails. Remove infected leaves.
Aphids: Sap-suckers that cluster on leaves—spray with water or insecticidal soap.
Flea beetles: Tiny jumping bugs that chew holes in young leaves. Row covers help.
Downy mildew: Fungal disease causing yellow patches. Improve airflow and avoid overhead watering.
Shopping Tips
Looking to grow your own or buy fresh beets?
Seeds: Choose varieties like ‘Detroit Dark Red’, ‘Golden’, or ‘Chioggia’ depending on your culinary goals. Look for non-GMO or organic-certified seed when possible.
Seedlings: Check that roots aren’t rootbound and leaves look vibrant. Avoid plants with signs of mold or pests.
Farmers Market or Store: Pick beets that are firm and smooth-skinned. Avoid soft spots or long hairy roots. Bright, perky greens are a bonus—they signal freshness!
Storage
Roots: Trim off greens (leave 2.5 cm or 1 in of stem), then store unwashed roots in a perforated bag in the fridge. Keeps for 2–3 weeks or more.
Greens: Use within a few days. Store in a damp cloth or bag in the fridge crisper drawer.
Cooked/Preserved: Cooked beets can be refrigerated for up to a week. They also freeze well (peeled and chopped) and can be pickled for long-term storage.
Culinary Uses
Beets are culinary chameleons, offering delicious versatility in both their roots and greens. Whether you’re a seasoned cook or a kitchen newbie, there’s plenty to explore here!
Beet Roots
The beetroot itself is probably the most familiar part—those deep red, purple, or even golden bulbs packed with earthiness and sweetness. You can enjoy beet roots in tons of ways:
Roasted: Roasting brings out their natural sweetness and softens the texture. Toss cubed beets with olive oil, salt, and your favorite herbs, then roast at 400°F (200°C) for about 30-40 minutes until tender. Perfect as a side dish or tossed in salads.
Boiled or Steamed: Simple and classic, boiling or steaming is a quick way to soften beets for salads or purees. Don’t peel them before cooking—just scrub and cook, then slip off the skins with your fingers once cool.
Pickled: Pickled beets add tang and a pop of color to your plate. Slice cooked beets and marinate them in vinegar, sugar, and spices for a delicious condiment or snack.
Raw: Thinly sliced or shredded raw beets add crunch and vibrant color to salads and slaws. Pair with citrus or creamy dressings for balance.
Juiced or Smoothies: Beet juice is a popular health drink, often mixed with apples, carrots, or ginger for an energizing boost.
Beet Greens
Don’t underestimate the greens—they’re nutritional powerhouses and deserve a starring role in your kitchen! Beet greens have a mild, slightly earthy flavor, similar to Swiss chard or spinach, and are packed with vitamins A, C, and K, as well as minerals like calcium and iron.
Sautéed: The easiest way to enjoy beet greens is by sautéing. Heat olive oil or butter in a pan, add minced garlic, then toss in chopped beet greens with a pinch of salt and pepper. Cook just until wilted—about 3-5 minutes—to keep their vibrant color and tender texture. Finish with a squeeze of lemon juice or a sprinkle of chili flakes for extra zing.
Steamed or Boiled: Lightly steaming beet greens softens their texture and reduces bitterness. Toss with a bit of butter, olive oil, or a drizzle of balsamic vinegar for a simple side dish.
In Soups and Stews: Chop beet greens finely and stir them into soups, stews, or broths near the end of cooking. They add nutrients and a beautiful splash of green.
Raw in Salads: Young, tender beet greens can be eaten raw! Mix them into green salads for extra crunch and nutrition. They pair well with citrus-based dressings and nuts.
Pesto or Sauces: Swap out basil or spinach for beet greens in pesto recipes. Blend with nuts, garlic, olive oil, and parmesan (or nutritional yeast for vegan) for a vibrant green sauce perfect on pasta or sandwiches.
Stir-fries and Grain Bowls: Beet greens hold up well in quick stir-fries. Toss with other veggies, tofu, or grains like quinoa and brown rice for hearty, nutrient-rich bowls.
Beet Green Chips: Similar to kale chips, toss beet greens with olive oil and sea salt, then bake at a low temperature until crispy for a healthy snack.
Beet Stems and Flowers
While less common, beet stems and flowers are edible too! The stems can be sautéed like the greens, adding a slightly crunchier texture. Beet flowers make a pretty garnish on salads or dishes, adding color and a mild beet flavor. By using the whole beet plant—from root to leaves and beyond—you’re embracing zero waste, boosting your meals with nutrition, and expanding your culinary creativity. Ready to dig in?
