Minnesota Sea Grant: Regents of the University of Minnesota. It spreads quickly through bulbils (small bulb-like structure), and fragments of the rhizomes (a type of underground stem). The PLANTS Database. The root can also be dried and ground into a powder [179], it can then be used as a thickener in soups etc, or be added to cereal flours when making bread [2]. Although Canadian populations of B. umbellatus appeared to be incapable of autonomous seed production (without external pollination assistance), plants were self compatible and produced more seed when self-pollinated (Eckert et al. Biological Invasions 1(2): 281-300. Follow all label instructions.

Further concerns have arisen regarding the role of B. umbellatus populations as an ideal habitat for the great pond snail (Lymnaea stagnalis), an intermediate host of a trematode (Trichobilharzia ocellata) responsible for swimmer’s itch (Rice and Dupuis 2009). Realized: Flowering rush was found at a third of sampled coastal wetlands on Lake Erie and Lake Ontario, although it was never a dominant species where it was documented (Trebitz and Taylor 2007). Flowering rush can also be easily grown from a rhizome cutting. It is capable of forming dense mats that could affect the availability of light, nutrients, and dissolved gasses in colonized waters (MPLP 2006). 1974) indicated that apparently the genus has become naturalized in North America at two separate locations, one near Detroit and another in the St. Lawrence River region.

Hand digging is feasible with small infestations but care must be taken to remove all parts of the plant - root fragments can drift with water movement and result in new infestations 2. North American triploid populations rarely flower and also have a limited ability to multiply and disperse via clonal reproduction, although they may have a greater ecological tolerance than diploid populations as a result of polyploidy or of greater investment in vegetative growth (Lui et al. 2003). 1996). Control Butomus umbellatus has a similar appearance to some native plants, such as common bulrush (Typha latifolia) (Jensen 2011). It is being provided to meet the need for timely best science.

Flowering Rush (Butomus umbellatus) General Characteristics Spread Abundance Control Disposal Methods Don’t Buy. (2003) speculated that even the densest populations of flowering rush may leave some space available for native species as a result of its particular growth form. Post-establishment survival was also over twice as high for North American populations as it was for European populations (Brown and Eckert 2005). Populations may be spread via the horticulture trade (Lui et al. There is currently no herbicide that targets B. umbellatus, but initial testing shows that a mid-summer application of imazapyr (labeled as the herbicide ‘Habitat’) during calm weather may be effective (MNDNR 2012, Parkinson et al. 126 pp. Discover RHS expert help and advice on growing, feeding, pruning and propagating plants.

Research Coordination Committee, GLPANS. 2009. Pretty pink flowers in umbrella-like umbels rise above the long slim leaves which turn from red to dark green as they mature. Infestations could also result in increased water temperatures and altered nutrient flows and/or sedimentation rates (Rice and Dupuis 2009). Flowering rush produces beautiful flowers and can be an excellent addition to ponds within its native range of the UK and other portions of Eurasia. ¡ Outcompetes native plants ¡ Limits water flow in irrigation canals ¡ Interferes with recreational activities ¡ Creates habitat for snails that carry swimmer’s itch ¡ Alters habitat for fish and wildlife Do NOT pull or dig!
