![]() ![]() The photographs here show the species in its typical range of metropolitan ecotones, from mown nature strip to less frequently managed verges to river muds dividing the minor channels of the Merri Creek above the gorge at Galada Tambore. It prefers slightly damper, calcareous sites, where it can grow so dense that it forms yellow meadows that dazzle in the sunshine. The same pattern is on display in NSW, where a correspondent at Kiama submitted a sample to Australian Town & Country for identification in 1900, but the first (digitised) botanical collection dates only to 1924. It grows in wet habitats, such as irrigation ditches. Meadow buttercup is a widespread and common perennial in meadows and pastures, and is also found in parks, gardens and at woodland edges. Initially a weed of domestic lawns and other cultivated places, the colonial presence of this species was often presumably wholly unremarkable. By 1909 the species was described by Ewart and Tovey as one of the two buttercups which were serious pests in Victoria, ‘intensely acrid useless for grazing,’ but following their advice apparently controllable in wet pastures by planting the dominating Birds Foot Trefoil (Lotus corniculatus).Īt SA, while the first formal collection appears only to have been made in 1892, the species was reportedly common around parts of Adelaide by 1879. Unpalatable, tolerant of mowing and happy to persist in feet wet conditions, it would soon be widespread on moist ground across the colony. Tall Buttercup is predominately a weed problem in hay meadows and pastures. Included on the laundry list of common weeds proclaimed by the Commonwealth in 1909 under its new Quarantine Act, Sharp Buttercup like most of the plants on that list had already conclusively established here long before the barn door was performatively closed by federal legislation.Ĭollected at Melbourne by von Mueller in 1853, Sharp Buttercup presumably arrived as a contaminant amongst the earliest imports of lawn and pasture seed. Tall Buttercup - Ranunculus acris, exotic and Noxious: Basal leaf blades pentagonal (5-sided) in shape that are mostly deeply divided into about 3 palmate lobes that again deeply divided into 2-3 acute segments. Leaves are typically dark green but may have lighter spots. The leaf blade is divided or deeply lobed into three broadly toothed segments. Leaves are also hairy, with long petioles. The stems are hairy and root at the nodes when they contact the soil. One of the most high-profile broadleaf weeds in this mix is buttercup (Ranunculus spp.), a species that turns fields into a sea of yellow blooms by mid- to late-spring. Biology Creeping buttercup is a creeping perennial plant that is usually fairly low-growing. Known to occur in king county Historically present, but thought to be eradicated. Sharp Buttercup (Ranunculus muricatus), a southern European mainstay of damp verges and river muds. In untreated pastures and hayfields, there are likely dozens of cool season broadleaf and grass weed species that blanket the landscape. The King County Noxious Weed Control Board has adopted this Noxious Weed List in accordance with RCW 17.10 and WAC 16-750. ![]()
