Vegetative characteristics

The Thuringian poplar grows as a perennial herbaceous plant that reaches heights of 50 to 125 centimeters. The leaves and flowers of the upper part are covered with felty star hairs ( indument ). The upper stem leaves are up to 10 centimeters long, three- to five-lobed and divided up to the middle, the lower leaves are pentagonal.

Generative characteristics

The flowering period extends from July to October. The flowers are arranged in a loose, racemose inflorescence . The hermaphrodite flowers are five-fold and with a diameter of 5 to 8 centimeters radial symmetry . The outer chalice has grown into a three-column shell and is shorter than the chalice. The five nailed petals are 2.5 to 4.5 inches long, hairy at the base, deeply edged at the tip and pink with dark veins.

The partial fruits are bare and wrinkled on the back.

The number of chromosomes is 2n = 40 or 44.

Occurrence

In German-speaking countries , it has only been introduced almost everywhere and has run wild. It is probably only native to the Pannonian region of Austria, where it occurs scattered in the federal states of Vienna , Lower Austria and Burgenland .

The Thuringian poplar grows best on nitrogen-rich , moist loam or clay soils , which can be somewhat salty . It prefers warm locations in summer and predominantly colonizes wasteland and alluvial areas on rivers, but also grows in the bank bushes. It is a character of the Arction association, but also occurs in societies of the Origanetalia order.

Taxonomy

The first publication of Lavatera thuringiaca was in 1753 by Carl von Linné . A synonym for Lavatera thuringiaca L. is Malva thuringiaca (L.) Vis.
