In the plant world, rhubarb and red chard are often mistaken for one another due to their visually similar crimson stalks, but they have distinctly different characteristics and culinary uses. As you begin to explore these two vibrant plants, it’s important to recognize the key differences to ensure they’re used appropriately in your cooking. Rhubarb, for instance, is botanically classified as a fruit and is renowned for its tart flavor, which makes it a popular component in desserts, often requiring sweetening.
On the other hand, red chard, a leafy vegetable from the beet family, offers an earthy taste and is packed with nutrients, suitable for a variety of savory dishes. While both share a color palette that ranges through shades of red and magenta, telling them apart is straightforward if you know what to look for. The texture of the leaves and the flavor profile of the stalks are your immediate clues, with Swiss chard having shinier, more ruffled leaves and a milder taste compared to rhubarb’s wide, triangular leaves and sharp tartness.
Rhubarb Overview
In your exploration of garden plants, rhubarb stands out for its perennial growth and unique culinary applications, particularly in pies due to its tart flavor profile. Dive into the specifics of rhubarb’s taxonomy, how to cultivate it in your garden, and its identifiable characteristics.
Taxonomy and Species
Rheum, the genus to which rhubarb belongs, is part of the Polygonaceae family. The species commonly known as rhubarb in culinary contexts is Rheum rhabarbarum. It is cultivated primarily for its fleshy stalks which have a noteworthy tartness.
Growing Rhubarb
Rhubarb is a hardy perennial that can thrive in your garden. Here’s what you need to consider for growing rhubarb:
Climate: Prefers cool climates; growth can be suboptimal in warmer zones.
Soil: Well-drained, fertile soil with plenty of organic matter.
Planting: Start with rhubarb crowns or divisions; situate in an area with full sun to partial shade.
Care: Minimal once established; keep soil moist and free of weeds, and apply a balanced fertilizer annually.
By following these guidelines, you ensure strong rhubarb plants that can be harvested for years.
Characteristics of Rhubarb
When discussing rhubarb’s characteristics, focus on the stalks and leaves:
Stalks: These are the edible portion, exhibiting a striking reddish color. Crisp and tart, these stalks are often used in desserts like pies and compotes.
Leaves: Rhubarb leaves are inedible and can be toxic due to high levels of oxalic acid. They are large and have a triangular shape, often with a green hue that can have red patches.
Keep in mind that while their appearance may be similar to red chard, rhubarb stalks are distinct in their culinary use and flavor.

Magnesium: Supports muscle and nerve function
Dietary Importance
You’ll find that chard is a more nutrient-dense option, which can be particularly important if you’re aiming to increase your intake of essential vitamins and minerals. Both rhubarb and chard contain potassium, beneficial for heart health. However, chard has a higher potassium content along with a richer complement of anti-inflammatory enzymes.
When considering their place in your diet, understand that chard’s lower caloric content accompanied by a higher water content makes it a hydrating and low-energy-dense food, possibly supporting weight management goals without sacrificing nutrient intake.
Rhubarb:
Potassium: Supports heart health
Calories: Low energy contribution
Red Chard:
Potassium: Higher than rhubarb for heart health
Water: Contributes to hydration
Calories: Low, supports weight management
Fiber: High, enhances satiety and digestion
Both rhubarb and red chard can be valuable additions to your diet. The choice between them may come down to specific nutritional needs or personal preference.
Potential Health Concerns
When you’re incorporating vegetables like rhubarb and red chard into your diet, it’s critical to be aware of possible health concerns associated with them. Each has distinct characteristics that can impact your well-being if not handled or consumed appropriately.
Rhubarb Toxicity
Rhubarb stalks are safe to eat, but the leaves contain oxalic acid, which is poisonous. Consumption of the leaves can lead to severe symptoms and may be fatal in extreme cases. Oxalic acid can bind with calcium in the body, which not only diminishes its nutritional value but can also contribute to the formation of kidney stones. If you experience symptoms of rhubarb leaf poisoning, which might include difficulty breathing, burning in your mouth, or stomach pain, seek medical attention immediately.
Toxicity: Primarily from leaves, not stalks
Symptoms: Stomach pain, difficulty breathing
Compound of concern: Oxalic acid
Considerations with Red Chard
Red chard, on the other hand, is high in nutrients like calcium, potassium, and vitamins; however, it also contains oxalic acid, especially in the leaves. While it’s not in a concentration high enough to be considered toxic, it can be a concern for individuals with a predisposition to kidney stones. To reduce the oxalic acid content, you can cook red chard, which lowers its level and its potential risk.
Oxalic acid: Lesser concern than rhubarb, but noteworthy for those susceptible to kidney stones
Cooking: Reduces oxalic acid levels
Remember to enjoy these vegetables for their taste and health benefits, but also be mindful of their potential health concerns.
Harvest and Post-Harvest
Proper techniques for harvesting rhubarb and red chard are crucial for maximizing their freshness and shelf life. Precise storage methods also play an essential role in preserving their quality after harvest.
Harvesting Techniques
Rhubarb:
Timing: Begin harvesting rhubarb in early spring, once the stalks reach a usable size, typically around 10–15 inches long.
Method: Grasp the base of the stalk, pull it sideways, and gently twist to break it off—avoid cutting as this can lead to rot.
Frequency: Harvest in moderation to ensure the plant remains productive; leave at least two-thirds of the plant intact to allow for continuous growth.
Red Chard (also known as silverbeet or bright lights):
Timing: You can start harvesting red chard leaves once they are about 8–12 inches tall.
Method: Pick the outer leaves first, cutting them near the base of the leafstalk to encourage new growth from the center.
Size Consideration: For tender leaves, opt for smaller sizes, similar to kale, whereas larger leaves can be harvested for a more robust flavor.
Storage and Preservation
Rhubarb:
Short-term: Store fresh rhubarb stalks in the refrigerator wrapped in a damp cloth or in a plastic bag for up to two weeks.
Long-term: For extended storage, rhubarb can be frozen. Cut the stalks into pieces and blanch them before freezing, or simply freeze them raw.
Red Chard:
Short-term: Keep unwashed red chard in the refrigerator in a plastic bag to maintain moisture. It should last about a week.
Long-term Option: Blanch the leaves and stalks for two minutes, then transfer them into ice water before draining and freezing for long-term use.
By following these specified techniques, you can effectively harvest and preserve rhubarb and red chard from your home garden to ensure they retain their quality and nutritional value.
