Rumex confertus is known to be one of the most serious invasive weed species infesting meadows, pastures and ruderal lands throughout the Central Europe. It grows quickly, reproduces from rhizomes and seed, and produces large quantities of viable seed. Its seed is adapted for wind and water dispersal and exhibits a high rate of germination. Rumex confertus flowering usually occurs late spring-summer. Along roadsides, waste places, meadows, river valleys.
