Rhubarb is a popular ingredient in many sweet and savory dishes, from pies and tarts to jams and sauces. One of the most common misconceptions about rhubarb is that it turns red when it’s ripe. But is this really true? In this article, we’ll delve into the world of rhubarb, exploring its unique characteristics, growth patterns, and the factors that influence its color.
Understanding Rhubarb’s Unique Characteristics
Rhubarb is a type of vegetable that belongs to the Polygonaceae family. It’s a perennial plant that grows from thick, underground rhizomes, producing large, leafy greens and colorful stalks. Rhubarb is often mistaken for a fruit, but it’s actually a type of petiole, which is a leafy stem that grows from the ground.
Rhubarb’s Growth Patterns
Rhubarb plants typically grow in the spring and summer months, producing new stalks and leaves throughout the season. The stalks can grow up to 2-3 feet tall, with some varieties producing longer or shorter stalks. Rhubarb plants require a period of cold weather to induce dormancy, which helps to promote healthy growth and fruiting.
Factors That Influence Rhubarb’s Color
So, what makes rhubarb turn red? The answer lies in the plant’s unique pigmentation. Rhubarb contains a range of pigments, including anthocyanins, carotenoids, and chlorophyll. Anthocyanins are responsible for the red, purple, and blue colors of many fruits and vegetables, while carotenoids produce yellow and orange hues. Chlorophyll, on the other hand, gives plants their green color.
The combination and concentration of these pigments can vary depending on factors such as:
- Variety: Different rhubarb varieties can produce different colors, ranging from deep red to pale green.
- Maturity: Rhubarb stalks can turn red as they mature, but this is not always the case.
- Light exposure: Rhubarb plants that receive more sunlight may produce more anthocyanins, resulting in a deeper red color.
- Temperature: Cooler temperatures can slow down the breakdown of chlorophyll, allowing the red pigments to become more visible.
- Soil quality: The pH and nutrient levels of the soil can impact the plant’s ability to produce certain pigments.
Debunking the Myth: Not All Rhubarb Turns Red When Ripe
While some rhubarb varieties do turn red as they mature, this is not a universal trait. In fact, many varieties remain green or produce a range of colors, including pink, yellow, and white.
Some popular rhubarb varieties that do not turn red include:
- ‘Victoria’: A popular variety that produces green stalks with a sweet, tender flavor.
- ‘Canada Red’: Despite its name, this variety produces stalks with a greenish-pink color.
- ‘Valentine’: A variety that produces bright red stalks, but only in certain growing conditions.
How to Determine if Rhubarb is Ripe
So, if rhubarb doesn’t always turn red when it’s ripe, how can you tell if it’s ready to eat? Here are a few tips:
- Check the stalks: Ripe rhubarb stalks should be firm, but not hard. Avoid stalks that are soft or mushy.
- Look for color: While not all rhubarb turns red, a deepening of color can indicate ripeness. Check for a rich, vibrant color, whether it’s red, green, or something in between.
- Taste it: Ripe rhubarb should have a sweet, tart flavor. Avoid stalks that taste bitter or sour.
Cooking with Rhubarb: Tips and Tricks
Rhubarb is a versatile ingredient that can be used in a range of sweet and savory dishes. Here are a few tips for cooking with rhubarb:
- Use the right variety: Different rhubarb varieties can have different flavor profiles and textures. Choose a variety that suits your recipe.
- Balance the flavor: Rhubarb can be quite tart, so balance the flavor with sweet ingredients like sugar or honey.
- Don’t overcook it: Rhubarb can become mushy and unappetizing if it’s overcooked. Cook it until it’s tender, but still crisp.

What is rhubarb and how does it grow?
Rhubarb is a type of vegetable that belongs to the buckwheat family. It is a perennial plant that grows from thick, underground stems called rhizomes. Rhubarb plants have large, leafy greens and long, stalky stems that are typically harvested for use in cooking and baking. The plant grows best in cooler climates with well-drained soil and full sun to partial shade.
Rhubarb plants typically take a few years to mature, and they are usually harvested in the spring when the stalks are tender and flavorful. The stalks can be harvested by cutting them off at the base of the plant, leaving about an inch of stem intact. This allows the plant to continue growing and producing new stalks throughout the season.
Does all rhubarb turn red when ripe?
No, not all rhubarb turns red when ripe. While some varieties of rhubarb do develop a reddish-pink color as they mature, others remain green or have a more pale yellowish color. The color of the rhubarb is determined by the variety, with some being bred specifically for their red color and others being more focused on their flavor and texture.
It’s also worth noting that the color of the rhubarb does not necessarily determine its ripeness or flavor. Rhubarb is typically ready to harvest when the stalks are tender and slightly tart, regardless of their color. The best way to determine if rhubarb is ripe is to taste it, as the flavor will be more sweet and less tart when it’s ready to eat.
What are some common varieties of rhubarb?
There are several common varieties of rhubarb, each with its own unique characteristics and uses. Some popular varieties include ‘Canada Red’, ‘Valentine’, and ‘Victoria’, which are known for their bright red color and sweet-tart flavor. Other varieties, such as ‘Rheinlander’ and ‘Crimson Cherry’, have a more greenish color but are still prized for their flavor and texture.
Some varieties of rhubarb are also bred specifically for their cold hardiness or disease resistance, making them well-suited to certain climates or growing conditions. When choosing a variety of rhubarb to grow or purchase, consider factors such as flavor, texture, and color, as well as any specific growing requirements or needs.
How do I know when rhubarb is ready to harvest?
Rhubarb is typically ready to harvest in the spring, when the stalks are tender and slightly tart. The best way to determine if rhubarb is ripe is to taste it, as the flavor will be more sweet and less tart when it’s ready to eat. You can also check the stalks for tenderness by gently bending them – if they snap easily, they’re ready to harvest.
It’s also important to harvest rhubarb at the right time to avoid damaging the plant. Rhubarb plants typically go dormant in the summer, and harvesting the stalks too late in the season can weaken the plant and reduce its productivity. Harvest the stalks when they’re between 12 and 18 inches long, and avoid pulling on the stalks or twisting them, as this can damage the plant.
Can I grow rhubarb in my garden?
Yes, you can grow rhubarb in your garden, provided you have the right climate and growing conditions. Rhubarb prefers cooler temperatures and well-drained soil, making it a great choice for gardens in the northern United States or other temperate climates. Rhubarb plants are also relatively low-maintenance, requiring only occasional watering and fertilization.
To grow rhubarb, choose a location with full sun to partial shade and well-drained soil. Plant the rhizomes in the early spring or fall, and water them regularly until they’re established. Rhubarb plants typically take a few years to mature, but they can produce stalks for many years with proper care. Be sure to divide and replant the rhizomes every few years to keep the plant healthy and productive.
Is rhubarb a fruit or a vegetable?
Rhubarb is technically a vegetable, although it’s often used in sweet dishes and desserts. From a botanical standpoint, rhubarb is a type of petiole, which is a leafy stem that grows from the ground. While it’s often paired with fruits like strawberries and raspberries, rhubarb is actually a savory ingredient that’s more closely related to vegetables like celery and asparagus.
Despite its classification as a vegetable, rhubarb is often used in sweet dishes and desserts, where its tart flavor adds a nice balance to sweet ingredients like sugar and fruit. Rhubarb is also a popular ingredient in savory dishes, where its flavor pairs well with ingredients like pork and chicken.
How do I store and preserve rhubarb?
Rhubarb can be stored in the refrigerator for up to a week, where it will keep its flavor and texture. To store rhubarb, trim the stalks to remove any leaves or woody ends, and wrap them in plastic wrap or aluminum foil. You can also freeze rhubarb for later use, where it will keep for several months.
To freeze rhubarb, chop the stalks into small pieces and blanch them in boiling water for 30 seconds to 1 minute. Then, shock the rhubarb in an ice bath to stop the cooking process, and package it in airtight containers or freezer bags. Frozen rhubarb is perfect for using in pies, tarts, and other desserts, where its flavor and texture will remain intact.
