Summary[edit] Description: Like all Rumex species, both native and non-native, Rumex venosus has a predilection for disturbance prone settings (e.g., roadsides) or for sandy soils. The sheathing stipules are characteristic of most genera in the Polygonaceae. Date: 1 June 2009, 09:58. Source: Rumex venosus. Author: Matt Lavin from Bozeman, Montana, USA.

Summary[edit] Description: Native, warm-season, perennial, rosette-forming herb when young, later becoming erect, branched and 50-80 cm tall. Leaves are paddle-shaped and up to 12 cm long, often with wavy margins. Flowers are very small and greenish red, occurring in distinctly separate whorls along the spikes. Small triangular fruits have hooked teeth, which allow them to cling to clothes and fur. Flowering is from spring to summer. Found in lawns, pastures and roadsides in full sun or partial shade, but is not restricted to wet areas as the name suggests. Native biodiversity. It may cause oxalate poisoning, but this usually only occurs when starving animals are grazing high densities of the plant. Poisoning is rarely a problem, as plants are usually scattered and large quantities need to be eaten to cause problems. Generally unpalatable, although some landholders report that it is readily eaten in summer. Becomes more abundant with overgrazing, but generally not present in large enough numbers to warrant control. Most effective control is to maintain a healthy vigorous pasture. Slashing is ineffective. Hoeing requires the taproot to be cut off at deeper than 15 cm below ground level. A number of herbicides are registered for control. Date: 20 June 2015, 13:44.

2011-05-13 Lower Austria, district Bruck/Leitha (in a - temporarily? - abandoned gravel pit - on rough gravel with hardly any humus covering; 250 msm Quadrant 7965/2).Not uncommon but avoiding carbonaceous soil; here, on 'raw' gravel, it seems to feel at home.German name: Zwerg-SauerampferSeveral sub-species are native to Austria, but to determine those fruit are necessary, which haven't developed here yet; I'll try and visit that place later in the year for sub-species ID.
