description

Appearance and leaf

Forage comfrey grows as a perennial herbaceous plant with thickened roots . With the stalks, it reaches heights of up to 2 meters. The above-ground parts of the plant are downy to stiff-haired, but not prickly haired .

The alternate leaves are simple . The upper stem leaves are sessile, short run down or more or less encompassing the stem . The approximately 25 centimeters long leaf blade is never heart-shaped. There are no stipules .

Inflorescence of the forage comfrey

Inflorescence, flower and fruit

The flowering period extends from May to August. The inflorescence is a terminal double wrap . It has no cover sheets .

The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope . The five sepals are fused into a 5 to 7 millimeter long calyx with usually pointed calyx lobes. The five petals are either initially pink and later blue or constantly purple. The corolla measures 12 to 18 millimeters in diameter. In the corolla tube there are five coronet scales, which are broadly triangular-lanceolate like the common comfrey, but not as wide at the base. The stamens of the stamens standing in a circle to five are narrower than the anthers.

The fruits are Klausen fruits , which disintegrate into four egg-shaped and upright partial fruits.

Chromosome number

The number of chromosomes is 2n = 36.

ecology

The spread of the fodder comfrey occurred mainly through humans z. B. with the topsoil; so the plant became a cultural relict and a cultural refugee.

Once naturalized, it can become a pesky weed that overgrows native species.

However, the plant provides the best composting material and mulch material.

It is also useful as a fodder plant for bees because of the abundant visit from insects .

Occurrence

The original range of the forage comfrey is Asia. It was once introduced as a fodder plant in numerous European countries and on the Azores , it became wild in a row and is now naturalized worldwide. In Central Europe he can be found in Germany , Liechtenstein , Austria and the Czech Republic . In Austria, forage comfrey was previously grown as pig feed and is now rarely found wild or naturalized on ruderal areas and floodplains . It occurs in all federal states except Salzburg .

Systematics

Symphytum × uplandicum was first described by Carl Frederik Nyman in Sylloge Florae Europaeae , page 80, in 1855 . A synonym for Symphytum × uplandicum are Symphytum asperum auct. non Lepech. and Symphytum peregrinum auct. non Lepech. . It is a hybrid of the rough comfrey and the real comfrey ( Symphytum asperum × Symphytum officinale ). Symphytum × uplandicum is in turn a parent of two hybrids described in 2009:

  • Symphytum × hidcotense P.D.Sell : The second parent is the large-flowered comfrey ( Symphytum grandiflorum ) DC.
  • Symphytum × perringianum P.H. Oswald & PDSell : The second parent is the oriental comfrey ( Symphytum orientale ) L.
