Rhubarb, a plant known for its tart stalks used in pies, tarts, and jams, has been a favorite among gardeners and cooks for centuries. With its vibrant green and red colors, it not only adds a pop of color to gardens but also provides a delicious and versatile ingredient for a variety of dishes. However, with numerous varieties of rhubarb available, choosing the best one to grow can be a daunting task. This article aims to guide you through the process of selecting the most suitable rhubarb variety for your needs, considering factors such as climate, desired stalk color, and disease resistance.
Understanding Rhubarb Basics
Before diving into the various types of rhubarb, it’s essential to understand the basics of this plant. Rhubarb is a perennial vegetable that thrives in cool, temperate climates. It prefers well-drained soil and full sun to partial shade. Rhubarb plants are typically hardy in USDA zones 3-8, making them a great addition to gardens in these regions. The plants grow from crowns, which are the underground stems that produce new growth. Each crown can produce multiple stalks, and with proper care, rhubarb plants can be productive for many years.
Rhubarb Varieties: An Overview
There are several types of rhubarb, each with its unique characteristics, advantages, and disadvantages. Some varieties are better suited for specific climates or uses, while others offer a combination of desirable traits. When choosing a rhubarb variety, consider factors such as stalk color, flavor, texture, and disease resistance. Popular varieties include Canada Red, Cherry Red, and Victoria, but there are many more to explore.
Color Varieties
Rhubarb stalks can range in color from a deep red to a light green. The color of the stalk does not necessarily affect the flavor, but it can impact the appearance of the final product. For example, red stalks can add a beautiful pink hue to jams and preserves, while green stalks may produce a more neutral-colored product. Some popular color varieties include:
- Green Petrovka: Known for its bright green stalks and sweet flavor.
- Crimson Wine: Offers deep red stalks and a rich, full-bodied flavor.

For example, if you plan to use your rhubarb for cooking and baking, you may want to choose a variety that is known for its tart flavor, such as ‘Timperley Early’ or ‘Stockbridge Arrow’. If you prefer a sweeter rhubarb, you may want to choose a variety like ‘Sunrise’ or ‘Crimson Wine’. You should also consider the growth habits of the plant, such as its mature size, spread, and productivity, to ensure that it will thrive in your garden.
What are some popular varieties of rhubarb for beginners to grow?
For beginners, some popular and easy-to-grow varieties of rhubarb include ‘Victoria’, ‘Canada Red’, and ‘Valentine’. These varieties are known for their cold hardiness, disease resistance, and high productivity, making them ideal for gardeners who are new to growing rhubarb. ‘Victoria’ is a classic variety that produces tender, sweet stalks with a mild flavor, while ‘Canada Red’ produces bright red stalks with a tart flavor. ‘Valentine’ is another popular variety that produces deep red stalks with a sweet, slightly tart flavor.
These varieties are also relatively low-maintenance and can thrive in a variety of soil types and conditions. They are also less prone to bolting, which means they are less likely to produce flowers and seeds, allowing you to harvest the stalks for a longer period. Additionally, these varieties are widely available at most nurseries and gardening stores, making them easy to find and purchase. With proper care and attention, these varieties can provide a bountiful harvest of delicious rhubarb for years to come.
How do I plant and care for rhubarb to ensure optimal growth and productivity?
To plant and care for rhubarb, start by choosing a location with full sun to partial shade and well-draining soil. Rhubarb prefers a slightly acidic to neutral soil pH, ranging from 6.0 to 7.0. Plant the crowns in early spring, as soon as the soil can be worked, or in the fall, about 8 weeks before the first frost. Space the crowns 3-4 feet apart, and water them well after planting. During the growing season, keep the soil consistently moist, but not waterlogged, and feed the plants with a balanced fertilizer in the spring and summer.
To ensure optimal growth and productivity, it’s essential to provide your rhubarb plants with proper care and maintenance. This includes removing any seed stalks that form, as they can reduce the plant’s energy and productivity. You should also divide and replant the crowns every 5-10 years to maintain their health and vigor. Additionally, keep the area around the plants weed-free, and mulch around the plants to retain moisture and suppress weeds. With proper care and attention, your rhubarb plants should thrive and provide a bountiful harvest of delicious stalks for years to come.
Can I grow rhubarb in containers, and if so, what are the best practices for container-grown rhubarb?
Yes, you can grow rhubarb in containers, provided you choose a large enough container with good drainage and a well-draining potting mix. A container that is at least 12-18 inches deep and 2-3 feet wide is recommended, as rhubarb has a deep root system. Choose a variety that is compact or dwarf, such as ‘Glaskin’s Perpetual’ or ‘Victoria’, as they are better suited for container growth. When growing rhubarb in containers, make sure to provide the plants with full sun to partial shade, and keep the soil consistently moist, but not waterlogged.
When growing rhubarb in containers, it’s essential to provide the plants with adequate nutrients and care. Use a balanced fertilizer that is specifically formulated for container-grown plants, and follow the instructions on the label for application rates. You should also repot the plants every 2-3 years, as the soil will eventually become depleted of nutrients. Additionally, keep an eye out for pests and diseases, such as slugs and powdery mildew, which can be more prevalent in container-grown plants. With proper care and attention, container-grown rhubarb can thrive and provide a bountiful harvest of delicious stalks.
How often should I harvest rhubarb, and what is the best way to harvest the stalks?
Rhubarb is typically ready to harvest in the spring, about 8-10 weeks after the plants emerge from dormancy. The frequency of harvest will depend on the variety, climate, and growing conditions, but as a general rule, you can harvest the stalks every 7-10 days. To harvest the stalks, simply grasp the base of the stalk and pull it away from the crown, taking care not to damage the crown or the surrounding stalks. You can also use a sharp knife or clippers to cut the stalks at the base, just above the crown.
When harvesting rhubarb, it’s essential to leave at least 2-3 stalks on the plant to allow it to continue growing and producing new stalks. Over-harvesting can weaken the plant and reduce its productivity, so be sure to harvest the stalks in moderation. You can use the harvested stalks immediately, or store them in the refrigerator for up to a week. Rhubarb can also be frozen or canned for later use, making it a versatile and convenient ingredient for a variety of recipes. With proper harvesting and care, your rhubarb plants should continue to thrive and provide a bountiful harvest of delicious stalks for years to come.
Are there any common pests or diseases that can affect rhubarb, and how can I prevent or control them?
Yes, there are several common pests and diseases that can affect rhubarb, including slugs, snails, aphids, and powdery mildew. Slugs and snails can chew holes in the leaves and stalks, while aphids can transmit plant viruses and reduce plant growth. Powdery mildew is a fungal disease that can cause a white, powdery coating to form on the leaves and stalks, reducing plant growth and productivity. To prevent or control these pests and diseases, use organic or chemical controls as needed, and maintain good garden hygiene, including removing any debris or weeds that can harbor pests or diseases.
To prevent pest and disease problems, make sure to provide your rhubarb plants with good air circulation, full sun to partial shade, and well-draining soil. You can also use physical barriers, such as copper tape or fine mesh, to deter slugs and snails. For aphid control, use neem oil or insecticidal soap, and for powdery mildew, use a fungicide specifically labeled for use on rhubarb. Additionally, divide and replant the crowns every 5-10 years to maintain their health and vigor, and remove any infected or damaged stalks or leaves to prevent the spread of disease. With proper care and attention, you can prevent or control common pests and diseases and maintain healthy, productive rhubarb plants.
