Rhubarb Measurements How much rhubarb do you need? 5 Imperial 1 bunch = 5‐8 stems 5‐8 stems = 1lb 1lb = 3 cups diced rhubarb Rhubarb 3 cups diced rhubarb = 2 cups cooked rhubarb Metric 1 bunch = 5‐8 stems 5‐8 stems = 2.2 kg 2.2 kg = 750 ml diced rhubarb 750 ml diced rhubarb = 500 ml cooked rhubarb www.GettyStewart.com Rhubarb Quiz—True or False Test your rhubarb know‐how with this fun yet informative little quiz. 6 1. Rhubarb is a fruit. False. Even though we typically use rhubarb like a fruit in the kitchen, it is technically a vegetable. A fruit is the fleshy part of a plant that comes from a flower and surrounds a seed. The part we use on rhu‐ Rhubarb barb is the leafstalk or petiole. But whatever, just enjoy! 2. Rhubarb leaves are poisonous. True. According to The US National Library of Medicine high levels of oxalates and anthraquinone glycosides are what make rhubarb leaves toxic. However, a 150 lb adult would need to eat about 11 lbs of rhu‐ barb leaves to cause death. While that’s not very likely, smaller quan‐ tities may cause a burning in the mouth and throat, difficulty breath‐ ing, diarrhea, eye pain, nausea, stomach pain, vomiting, kidney stones, seizures, or coma. All reasons to avoid eating rhubarb leaves. 3. Rhubarb leaves should not be composted. False. Rhubarb leaves do not pose any danger to the vital organisms in your compost or soil. You can compost them or use them as mulch. www.GettyStewart.com Rhubarb Quiz—True or False 4. Rhubarb does not like cold winters. False. Rhubarb is perfect for cold climates. This cool season perennial is drought tolerant and actually needs a freezing cold dormant season to stimulate spring growth—perfect for the prairies! It does not grow well in warmer climates, nor does it enjoy hot summers. Expect its growth to slow considerably in heat of July and August. 5. Do not pick rhubarb after it flowers. False. Rhubarb is safe to harvest all season long. However, you’ll get 7 the most tender stalks before rhubarb has flowered or gone to seed. How quickly rhubarb bolts depends on tem‐ perature (the warmer Rhubarb the quicker), age (the older the quicker ) and the variety (Canada Red and Valentine are less likely to bolt). By trimming the flower stalks as soon as you see them, you’ll en‐ courage more growth, so you’ll be able to harvest more rhubarb. Use the flowers in a mixed bouquet. www.GettyStewart.com Rhubarb Quiz—True or False 6. Pick rhubarb when the stalks are red. False. Color indicates variety, not ripeness. Rhubarb varieties may be all green, a mix of green and red or all red. Canada Red and Victoria varieties are vibrant red and slightly sweeter than others. Harvest rhubarb when stems are 8 to 15 inches (25‐40 cm) long. 7. It is better to pull rhubarb stalks than to cut them. True. The plant is less likely to rot and will recover more quickly when stalks are pulled instead of cut. Start from the outside of the plant 8 and work toward the middle. Run your hand down the stalk until close to the ground then gently pull with a little twist. That said, rhu‐ barb is tough and will recover if you prefer cutting the stalks. Rhubarb Leave at least one third of the stalks to promote healthy growth. www.GettyStewart.com Rhubarb Quiz—True or False 8. Rhubarb is a good source of fibre and anti‐ oxidants. True. Rhubarb is low in calories (when not in pie!) and a good source of fibre,

  • Rhubarb Rheum Rhabarbarum
    Rhubarb Rheum rhabarbarum Rhubarb is an herbaceous, cool-weather perennial vegetable that grows from short, thick rhizomes. It produces large, triangular-shaped poisonous leaves, edible stalks and small flowers. The red-green stalks, which are similar to celery in texture, have a tart taste and are used in pies, preserves, and sauces. The leaves contain the toxic substance oxalic acid, a nephrotoxic which is damaging to the kidneys and may be fatal in large amounts but generally causes shortness of breath, burning sensations in the mouth and throat, coughing, wheezing, laryngitis, and edema. If the leaves have been ingested do not induce vomiting but call the Poison Control Hotline. Oxalic acid will migrate from the leaves to the stalks of plants that have been exposed to freezing conditions, therefore those stalks should not be consumed. Soil Requirements Rhubarb has a wide range of acceptable pH, from 5.0-6.8 which makes it well-suited for a Connecticut garden. Have a soil test done through the UConn Soil & Nutrient Analysis Lab and follow the recommendations a year before planting if possible. Amending the soil with aged manure or well-rotted compost will increase plant production. Location Selection & Planting Rhubarb should be planted in an area with full sun or light shade where it will be out of the way, at one end or side of the garden, as it will remain productive for 5 or more years. They should be planted in an area with good drainage or in raised beds. Rhubarb roots may be planted or divided in the early spring while they are still dormant.

  • Preserving Rhubarb
    OREGON STATE UNIVERSITY Extension Service SP 50-882, Revised June 2015 Preserving Rhubarb Rhubarb, which looks like a pink or red celery stalk, is botanically a vegetable, but is used like a fruit. It is most often found in pies and sauces, but can also be added to muffins, fruit crisp and made into jams and jellies. The stalks have an extremely tart flavor so require some sort of sweetener to make them palatable. Rhubarb also can be combined with sweet fruit such as strawberries to cut down on the sugar needed. There are basically two types of rhubarb; 1) hot house-grown, which has pink or light red stalks with yellow leaves, and 2) field-grown, which has dark red or green stalks with green leaves. The hot house varieties have a somewhat milder flavor and are less stringy. Rhubarb can be canned as a sauce, frozen or dried. When combined with strawberries, peaches or other fruit, it can make a great fruit leather. Rhubarb can also be made into fruit spreads, relish or chutney. To Can: (Hot pack only): Select young, tender, well-colored stalks from the spring or late fall crops. Trim off leaves. Wash stalks and cut into ½-1-inch pieces. In a large saucepan, add ½ cup sugar for each quart of rhubarb. Let stand until juice appears. Heat gently to boiling. Immediately pack mixture into hot jars, leaving ½-inch headspace. Remove air bubbles. Wipe jar rims and adjust lids. Process in a boiling water canner, 15 minutes for pints and quarts. After processing, take canner off heat.

    MEDlCINAL PLANTS OF JAMAICA. PARTS 1 & 11. By G. F. Asprey, M.Sc., Ph.D. (B'ham.), Professor of Botany, U.C.W.l. and Phyllis Thornton, B.Sc. (Liverpool), Botanist Vomiting Sickness Survey. Attached to Botany Depart- ment, U.C.W.l. Reprinted from the West Indian Medical Journal. Vol. 2 No. 4. Vol. 3 No. 1. MEDICINAL PLANTS OF JAMAICA G. F. ASPREY AND PHYLLIS THORNTON PART I The use of local plants for medicinal remedies is a very prevalent practice in Jamaica. Among the poorer families, the morning meal frequently consists of nothing more than a cup of bush-tea prepared by steeping the leaves in hot water, with perhaps a small piece of bread or a little corn meal porridge. It is perhaps significant that the term breakfast is not used but 'taking' or ‘drinking' tea is substituted. Many of the plants used for treatment of colds and indigestion also provide the normal morning drinks. The large number of 'cold', 'fever' (which includes malaria) and 'indigestion' remedies is of some interest as providing a guide to the frequency of these complaints. The claims made for some of the plants may occasionally be justified by their chemical constituents. Some of them are, or have been, in the pharmacopoeias. On the other hand, in many cases the claims either have little justification or remain to be substantiated. Many of the doses used are of an unpleasant and even drastic nature. This may account for their popularity in view of the general impression that medicine must be unpleasant to be efficacious.

  • The Return of the Rhubarb by Carol Quish, Uconn Home & Garden Education Center
    The Return of the Rhubarb By Carol Quish, UConn Home & Garden Education Center The appearance of the first leaves of my rhubarb plants unfolding are the best sign of spring for me. Those little shoots spark hopes of winter’s end and a new season’s start, bringing renewal of life to all living things as well as to my garden. Rhubarb’s return is exciting! Rhubarb is one of three hardy perennial vegetables commonly grown in Connecticut. The other two are horseradish and asparagus. These three were common mainstays in our grandparents’ gardens with rhubarb being the first fresh vegetable available before mass transportation made shipping food grown in warmer climates to us possible. It was often referred to as a ‘spring tonic’ after a long winter of canned, frozen and stored food from the root cellar. Pick as a stalk fresh from the garden and rhubarb smells tangy and sour, just like its taste. If you have never bitten into a freshly picked rhubarb stalk, imagine a cross between celery and sour-green apple that gets your cheeks twisting with its tartness. For this reason rhubarb is commonly cooked with sugar into many kinds of baked-goods. Stewed rhubarb is also a wonderful dish consisting of chopped stems simmered in water with a bit of sugar and is really great served with dollop of crème fraiche on top. Rhubarb is often combined with strawberries or other fruits in pies and jams. The strawberry offers sweetness and a more reliable red color to foods. Rhubarb can be added raw to smoothies and salsas.
