Variety traits
Rheum rhabarbarum L.
A morphological trait defined by the distance from the soil surface to the highest point of the vegetative organs or the flower stalk, used for variety identification and agronomic management.
In the reference 3 varieties crop Rhubarb, where this is mentioned in the description.
According to variety testing protocols, rhubarb height is measured from the soil surface to the most developed leaves during the appearance of flower stalks. Mature plants range from 80–90 cm in the leaf rosette phase to 1.5–2.0 meters during active flowering, with height serving as a key varietal parameter.
Height and overall habit determine the planting density, which requires at least 1 square meter per plant to prevent shading. Intensive vertical stretching of flower stalks signals the need for their removal, as the active growth of generative organs depletes plant resources and reduces the yield of marketable petioles.
