![]() Further experiments are needed to assess whether there is a viability of the root system after shoot senescence due to extreme drought. It features large, pointed, dark green leaves up to 8 inches long that have a coarse, hairy texture. The plant grows slightly taller than it is wide. It also can be a nice addition to a wildflower garden and container plantings. The water deficit affected the growth and metabolism of comfrey plants, but adjustments in photosynthetic apparatus and increased dry mass productivity indicated a possible adjustment to severe drought. Comfrey ( Symphytum officinale) is a perennial flower that grows in clumps naturally along riverbanks and in grasslands. The plant aerial parts were more visually affected than the roots, which showed secondary growth after the water restriction imposition, a possible response of tuberization to drought. Photochemical activities were affected in the first days, with less intensity on the seventh day for the photosystem II performance index (PI abs). This plant has medium severity poison characteristics. Comfrey has also been used in veterinary medicine ( Rabinovich, 1981 ). Native Americans also recognized its healing powers and included comfrey in their therapeutic armamentarium ( Hamel and Chiltoskey, 1975 Stammel, 1986 ). Commonly known as Comfrey this plant is usually used as a homeopathic remedy which does not typically exhibit side effects and harmful drug interactions. Commonly found throughout Europe and parts of Asia, the plant also naturalized in North America, where it rapidly spread. Symphytum officinale (Common Comfrey) is a coarse, spreading perennial forming a clump of long, elliptic, dark green leaves, 10 in. Symptoms of water deficit were evident from the third day onwards, such as leaf wilt and senescence of a greater quantity of leaves, as well as reduction of stomatal conductance. Symphytum Officinale from Boiron® may support and promote the healing of bones. ![]() Climatological data, growth parameters, pigment content, stomatal conductance, chlorophyll a fluorescence, Normalized Difference Vegetation Index, plant morphological responses, and anatomical differences of roots were evaluated. We aimed to assess the morphophysiological responses of comfrey to short-term severe water restriction (seven days) and to a control treatment under irrigation. On the growing conditions and physiological responses of this plant to stress are scarce. Symphytum officinale, commonly called comfrey, is a large, coarse, tuberous-rooted, clumping perennial (to 3 tall and 2.5 wide) that is primarily grown today. Symphytum officinale, comfrey, is a medicinal plant known for its healing properties. ![]()
