To propagate from seeds, plant in moist soil and transfer to the margins of your pond once sprouted and somewhat established. Eckert. Diploid populations of B. umbellatus can reproduce sexually via seed production and clonally via the branching and fragmentation of rhizomes and the production of small bulbils on both the rhizomes and inflorescences (Lui et al. It is also very difficult to eradicate once established. Interim Invasive Species Plant List. Available http://www.issg.org/database/species/ecology.asp?si=610&fr=1&sts=sss&lang=EN. In fact, muskrats are thought to be a factor in the spread of this plant. This information is preliminary or provisional and is subject to revision.

Care Tips - Divide Butomus umbellatus on a regular basis to encourage flowering. White, D., E. Haber, and C. Keddy. 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. Since then, it has become an established invasive species in many locations. Some animals, such as muskrats, frequently eat these rhizomes. Grassy rush; Water gladiolus; Butomus junceus Turcz.

Minnesota Sea Grant. Current research on socio-economic impact of Butomus umbellatus in the Great Lakes is inadequate to support proper assessment. Public and private landowners are required by state law to eradicate this plant when it occurs on their property. Suggested planting locations and garden types Wildlife Gardens Cottage & Informal Garden. 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. Find specific plants with our Plant Finder & Plant Selector. However, it can become problematic in ponds and gardens elsewhere and is not recommended outside of its native range. 2 pp. 90 pp. Variation in sexual and clonal reproduction among introduced populations of flowering rush, Butomus umbellatus (Butomaceae). ¡ 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! Flathead Lake (MT) has been infested by monocultures of flowering rush that have inhibited boat passage and reduced open water availability for swimming and fishing. Flowers: June/July.

Depth of water is from soil surface to water surface not including top dressing – planting depth 10-25cm Flowering rush is a perennial freshwater aquatic plant that grows in lakes, rivers, and wetlands. 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.

Journal of Great Lakes Research 33:705—721. 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. Flowering rush tends to form large clusters of plants and can easily crowd out native species. For one, this species can be hard to distinguish from other, native species unless it is in bloom, and therefore a permit is absolutely required to remove it to help prevent the accidental eradication of native species. July 2009 What is flowering rush? Flowering rush can displace native riparian vegetation, and can be an obstacle to boat traffic. This plant will grow at the margins of a water source, growing tall above the waterline, as well as completely submerged. Sampling along the St. Lawrence River in Quebec suggested that B. umbellatus was less common than purple loosestrife (Lythrum salicaria) but tended to be much more invasive when present. (2) Stem/Leaves: The stem is green and triangular in shape.The leaves can grow to be 3 ft. long and the tips are often spirally twisted. 2010, Jensen 2011). However, many locations have outlawed this plant due to its invasive properties. Butomus umbellatus (Flowering rush) will reach a height of 1.5m and a spread of 0.45m after 2-5 years. 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. It contains more than 50% starch [13]. It is on New York State’s Interim Invasive Species Plant List (NYDEC 2011). (Cold Water & Plecos), Do Pond Fish Hibernate? It tends to be an easy plant to care for, and will spread enthusiastically. Potential: Butomus umbellatus can displace native riparian vegetation via competition and could diminish native biodiversity as a result (MPLP 2006). 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.

Flowering rush is not thought to be toxic. 12 pp. 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). We maintain a planting depth of 40 cm. 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. It is capable of forming dense mats that could affect the availability of light, nutrients, and dissolved gasses in colonized waters (MPLP 2006). Phylum: Magnoliophyta - Class: Equisetopsida - Order: Alismatales - Family: Butomaceae. Rice, P. and V. Dupuis.

Flowering rush rhizomes are rich in starch, and some people do choose to eat them. Physical Butomus umbellatus spreads by floating seeds and vegetatively by rhizomes and root pieces (Campbell et al.
