Quotes about MacDonald

Saviez-vous qu’il existait des dizaines de variétés de rhubarbe? Certaines à tiges vertes, rouges, courtes ou longues? Une grande majorité de celles qu’on cultive encore aujourd’hui proviennent de Chine, Russie et Mongolie. Elles auraient été introduite en Amérique du Nord au début du 19e siècle et servaient, en grande majorité, à la confection de tartes; une tradition des anglo-saxons appelée « pieplant ». C’est justement à cause de son utilisation « sucrée » qu’elle a été classée comme un fruit par la Direction des Douanes de New York en 1947. Mais en réalité, les livres de botanique la classe comme un légume. Par ailleurs, l’une d’entre elles a été créée au Québec dans les années 1920 par le professeur Harold Murray du MacDonald Agriculture College: la « MacDonald ». Ce cultivar aux longues tiges rouges (jusqu’à 2 mètres) peut servir à d’autres usages insoupçonnés. Justement, une entreprise du Lac-Brome, La Rhubarbelle, utilise d’anciens cultivars de rhubarbe notamment la « MacDonald » pour confectionner des jus haut de gamme. Comme ce jus est disponible dans quelques établissements seulement dont le IGA Pépin de Saint-Hilaire, j’avais bien envie d’y goûter cette fin de semaine. Malheureusement, j’ai eu beau faire les allées, demander aux commis, impossible d’en trouver. Si vous avez davantage de chance que moi, j’aimerai bien avoir vos commentaires. Bonne dégustation!

This is a variety of Rhubarb that is from Canada! It was bred at the Macdonald College of McGill University in Quebec in the 1920’s. We grew it from seed that was obtained through Seeds of Diversity. Although the name is Macdonalds’ Seedless, it still produces seed stalks and it too had a noticeable upright form of growth. We have 2 or 3 starter clumps of Macdonalds’ Seedless at the museum and are hoping that it will establish itself over the next couple of years.

MacDonald is a snappy "new model" Rhubarb. The attractive features are the new bright red color combination and a “pick up” that will surprise you. It “gets into high” so quickly that you can cut stalks from it a year sooner than you can from the old style green-stalked varieties. Another great improvement in the new MacDonald is its excellent quality, sweeter than common Rhubarb and requiring less sugar. Plant some of this splendid red Rhubarb this year. It yields heavily and lasts a lifetime. When once you have tried MacDonald you will grow no other. ENDORSED BY MacDONALD COLLEGE — Prof. L. G. Bunting, MacDonald College, Quebec, where this variety was originated, writes: “MacDonald is very highly colored, attractive, red stalk, of large size, productive, very tender and succulent, and of excellent quality, and particularly valuable for pie and desserts. Its color, when cooked without peeling, is as attractive as that of raspberries.” REQUIRES LESS SUGAR — “Hardy Fruits” Magazine, Winnipeg, Canada, describes MacDonald as follows: “MacDonald requires less sugar for cooking than any of the old standard varieties.
