The list of references for all nonindigenous occurrences of Butomus umbellatus are found here. You can divide flowering rush, but you should keep in mind the fact that dividing the plant will likely lead to the propagation of more plants. Butomus Umbellatus. Despite its name, flowering rush is not closely related to true rushes but is, in fact, a unique flower with a genus and family (the Butomaceae) all to itself. Accessed 20 March 2012. Propagation Propagate by seed sown as soon as ripe or by rhizome division in spring. In fact, a recommendation for limiting the spread of flowering rush is to limit disturbance, as it is able to spread easily from bulbils that detach and float as well as rhizomes. The biology of Butomus umbellatus in shallow waters with fluctuating water level. Staniforth, R.J. and K.A. Accessed 2011. 15 pp. Canadian Field-Naturalist 94(3):333—336. Great Lakes Panel on Aquatic Nuisance Species (GLPANS). It can tolerate water as deep or deeper than 2 metres, extending to the deepest range of emergent marsh species. Most B. umbellatus populations in the Great Lakes are diploid and capable of producing abundant viable seed, although the major method of reproduction appears to be clonal (Lui et al. 1996). Top tip: Butomus hates being confined in a small basket and flowers best in 20cm water. Triploid populations also appear to be spread more commonly through the horticulture trade. Canadian Journal of Botany 78(4):437 —446.

Shift in wetland plant composition and biomass following low-level episodes in the St. Lawrence River: looking into the future. 2009. It spreads quickly through bulbils (small bulb-like structure), and fragments of the rhizomes (a type of underground stem). However, in southern Lake Champlain, B. umbellatus forms dense stands that appear to displace native species (Marsden and Hauser 2009). In areas where flowering rush is native, such as the UK, it is an important plant for dragonflies and damselflies. For extra colour and length! Invasive Plant Atlas of New England (IPANE). It is possible that plants naturalized in the St. Lawrence River region originated in eastern Asia, and those naturalized in the Detroit area originated in Europe or western Asia. Butomus umbellatus. Lui et al. Flowering rush is native to Europe and Asia but is invasive elsewhere. It grows along lake and river shores as an emergent plant. Relative to native European populations, Brown and Eckert (2005) found that nonindigenous North American diploid populations invested much more biomass in reproduction and were more likely to produce both inflorescences and clonal bulbils. However, it does behave similarly to true rushes, being most commonly found in moist soils such as those present in wetlands, marshes, along creek beds, and pond margins. Flowering rush can also be easily grown from a rhizome cutting. First observed in 1897 in North America. 2012. (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. Accessed 20 March 2012. Flowering rush (Butomus umbellatus). Flowers: June/July. If completely submerged, this plant is much less likely to produce flowers, and should be initially weighed down or placed in a pot at the bottom of the pond until its roots are able to hold it in place.

When flowering rush is in bloom, it produces clusters of attractive pink blooms, which look somewhat similar to cherry blossoms, and this is what most easily distinguishes it from true rushes.

Bees, flies, butterflies, and moths also visit this plant and pollinate its flowers. 1996). Potential: Stands of B. umbellatus can become thick and undesirable, even in its native range (Hroudová et al. 2006. 2003). Flowering rush could also provide structural habitat for some fish species, particularly those that depend on vegetation for spawning (Rice and Dupuis 2009). Is Flowering Rush Edible? Flowering rush is a perennial aquatic plant in the Butomaceae family. This plant will grow at the margins of a water source, growing tall above the waterline, as well as completely submerged. Flowering rush tends to form large clusters of plants and can easily crowd out native species. Folia Geobotanica and Phytotaxonomica 28(4):413—424. Seizer, M. 2009. If pieces of rhizomes break off, they can even travel in water currents and establish quite far away. Grow in full sun in fertile mud at the edge of a pond or in water up to 25cm deep. 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). West of Niagara Falls, the taxon was first collected near Detroit (Wayne County, Michigan, in Brownstown Township and at River Rouge) in 1930 by O. Higman, P., and S. Campbell. In the latter, B. umbellatus has colonized an estimated 150 miles of the 300 mile main canal, threatening water availability for potato and cash crops and requiring removal every 2 or 3 years. Populations may be spread via the horticulture trade (Lui et al. 2005). Flowering rush is a beautiful addition to many ponds within its native range, but it is best to consider planting a different species if you live elsewhere.
