But there is also plenty more to learn about this great vegetable. Let’s start with the facts and by the end, you’ll find five great recipes, none of them are for pie, enjoy!

What is Rhubarb

Rhubarb is a vegetable, not a fruit. However, it is usually sold and used as a fruit. The latin name is Rheum rhabarbarum. The perennial plant grows in single stalks with one big leaf at the top of each stalk.

The stalks have a light red color that turns more green as the stalks get bigger. Young examples are tender and can be eaten as they are but older stalks need to be peeled. It is only the stalks that are consumed.

How does Rhubarb Taste

Eaten raw the stalks is sour and very tart. It has an aromatic fruity flavor that like most flavors are hard to describe. Somewhat like the combination of an almost fully ripened strawberry and a granny smith apple maybe. Fresh and crisp but not a very distinct flavor.  The texture raw is similar to a stick of celery.

More or less all recipes call for sugar. If you grew up with rhubarb in your garden you probably tried dipping a raw stalk in sugar and then eating as a child. This changes it and brings out the flavor and reduces the tartness and acidity.

Is It Poisonous?

Yes, it is poisonous. It contains oxalic acid which is a corrosive acid. Therefore the leaves shouldn’t be consumed. The stalks also contain some oxalic acid but in far less quantities so they are safe to eat.

How To Grow Rhubarb

If you have a garden or somewhere else to grow rhubarb it is a great thing to have. If you take care of it you will have a safe supply for the next 20 years, maybe even longer.

You can grow them from seeds but that’s not common. It takes much longer and the chances are it will die on you. Instead, go for an already grown plant. You’ll have no problem finding one in your local garden shop.

You can plant it anytime as long as the soil is fairly warm. Spring and fall work best. During the first summer, you shouldn’t harvest any of the stalks. This makes it stronger for the coming year and it will produce more. However, I have taken just a few stalks and mine and it survived so you can take the chance.

Once the plant is rooted you should leave a few stalks by the end of each season. This is for the same reason as you did when first planting it, to make it stronger the following year. The rhubarb might produce flowers, those should be removed, they look kind of cool but the energy for the flower means less stalks for you.

During the season you will also need to fertilize it with manure or other types of fertilizers. Also make sure to water it if it isn’t raining, especially during the summer months. It likes the sun so try to find a sunny place to keep it.

After 4-6 years the rhubarb will have grown large and then you can dig it up and split it. This will give you more plants and keep it producing more. Make sure each split part of the rhubarb have at least one or two stalk buds that look whole and healthy.

All in all, it is very easy to grow and requires very little work, give it some love and water and it will give you new stalks all season long. Just remember these points.

  • Get a plant, not seeds. Plant it in a sunny place.
  • Fertilize and provide water
  • Remove flowers and split once it’s big

Where in the World Do Rhubarb Grow?

Rhubarb is a cool climate vegetable so it can’t be grown successfully in too hot climates. It works great in the Northern States of the US and in Canada. It is also commonly grown in most parts of Europe.

How To Harvest Rhubarb

Harvesting is as easy as it gets. Once a stalk is big enough just take a firm grip on it and pull it out. It should come out easy. If it happens to sit firm you can cut it off close to the soil. Remove and discard the leaf and rinse in water. Done.

When Should Rhubarb Be Harvested

Here’s the great thing. You can harvest all through summer. As long as there are new stalks growing you can pick as much as you need. I live in Sweden and I usually start picking in May and pick them from time to time until October. Just take the biggest ones and leave the small to get bigger.

How To Store Rhubarb

This is easy. First, don’t harvest unless you plan on eating the rhubarb. The best place to store it is not to harvest it, at least not as long as it is reasonably warm. Once you’ve harvested some they will keep for at least a week in the fridge if they are clean and not damaged.

If you are harvesting much rhubarb you can freeze it as well. Just rinse in cold water and cut into pieces and freeze as they are. A great thing to have in the freezer during those winter months.

Rhubarb Varieties

There are around 100 different varieties of rhubarb and they all have different characteristics. Some grow early in spring, some get long, more red, more green, sourer or tart. The best idea is to simply go to your local garden shop and ask what types they have and which suits your garden best.

Rhubarb History

The root of the rhubarb has been used in Chinese medicine for thousands of years. The plant reached Europe via the Silk Road in the 14th century. It also spread to Europe via Russia by land. The stalk of the rhubarb wasn’t popularized until the 18th century when the cost of sugar had been decreased. The variety that was used then was the so-called Siberian rhubarb which is the ancestor of modern rhubarb.

Turn the meat a few times during cooking and adjust the time since it can vary.

Once cooked remove the meat and pour the juices into a pot. With a spoon remove most of the fat and then reduce the juice into a slightly sticky syrup.

Cut four slices of the meat and brush with the syrup and serve. If you prepared the meat beforehand you can reheat it when it’s cut in a pan with some of the syrup.
