In the global screen used, there were ten fragments that were found in L. alatum and not in European L. salicaria, but only two of them were observed in North American L. salicaria. It was introduced to the United States and Canada as an ornamental for wetlands in the 1800s. Its flowers are extremely attractive to bees and butterflies. Two characters (M-CAG/E-AAG: 325 bp and M-CAG/E-AGG: 350 bp) were present in L. alatum and a few plants of L. salicaria in Massachusetts and Wisconsin. 1914, non Sessé y Lacasta & Moçiño 1888.

Found still blooming on Aug 10 at Iron Horse prairie SNA. (A) M-CAA/E-AAG: 472 bp, which is found in L. alatum and both allopatric and sympatric L. salicaria, and (B) M-CAG/E-AGG: 300 bp, which is found in L. alatum and only sympatric L. salicaria. Your email address: (required) North American L. salicaria formed its own distinct cluster within the larger L. salicaria group, with the European and cultivar samples clustering separately from the North American group. DC. ex Colla Lythrum salicaria var. In states where they may be grown legally, they should be sited in medium to wet soils in full sun to light shade. Lythrum alatum - Winged Loosestrife by bob in swamp. Lythrum salicaria var. The morphological intermediacy of these populations is consistent with their being hybrid swarms, but the molecular evidence does not support this conclusion, as the sympatric populations of L. alatum and L. salicaria did not carry any more of the unique L. alatum characters than did the allopatric populations. Individual patterns of AFLP variation in the Michigan survey of allopatric and sympatric populations of North American Lythrum salicaria and L. alatum. In the Michigan screen of sympatric and allopatric populations, there were 123 characters found to be unique to L. alatum and 19 that were shared by some individuals of the two species. It is in flower from June to August, and the seeds ripen from August to September. Lythrum salicaria is a herbaceous perennial plant, that can grow 1–2 m tall, forming clonal colonies 1.5 m or more in width with numerous erect stems growing from a single woody root mass. Sakai AK, Allendorf FW, Holt JS, Lodge DM, Molofsky J, With KA, et al. gracilior Turcz. Please, research before posting negative comments. Only one of these was restricted to sympatric populations of L. salicaria and thus could have introgressed; however, it was also found in European populations of L. salicaria and as a result may have been introduced. Species plants are classified as noxious weeds in the State of Missouri. Web design and content copyright © 2006-2020 couldn't find them in any of my reference books. Love your site. Commonly known as loosestrife (a name they share with Lysimachia, which are not closely related), they are among 32 genera of the family Lythraceae. This indicates that these cultivars have not extensively hybridized with North American L. salicaria, and the integrity of the cultivars in nursery stock remains. 4A); however, only one character (M-CAG/AGG: 300 bp) was found to be in L. alatum and only sympatric populations of L. salicaria (Fig. Grows in Sun to Part Sun. 6 purplish brown stamens extend out of the throat with the single greenish style hidden inside the tube. Lythrum Plant Growing and Care Guide. vulgare DC. Lythrum alatum aka Winged Loosestrife. Reed canary grass is present and expanding. Synonym Full Citation Basionym Type; Lythrum cordifolium Lythrum cordifolium Nieuwland, Amer. One other character (M-CAG/E-AAG: 650 bp) was found in L. alatum and two of the L. salicaria cultivars (Morden's Gleam and Happy). Note: All comments are moderated before posting to keep the riff-raff out. Lythrum salicaria var. All rights reserved. Ten AFLP characters were identified in L. alatum but not in European L. salicaria. Sixty-six characters were fixed in both species, so could not be used to evaluate whether introgression had occurred. It infests waterways across the entire continental U.S. (with the exception of Florida below the panhandle) and Canada below the Arctic Circle. A fourth species of Lythrum is now recognized in BC: Lythrum alatum (winged loosestrife). Common Names: Loosestrife, Purple Loosetrife, Purple Willow Herb, False grass-poly, Red Sally. The morphological data also supported introgression between L. alatum and L. salicaria, as most of the North American L. salicaria populations had individuals that carried the L. alatum traits alternate leaf placement and 1–2 flowers per leaf axil. Location and mean plant height, leaf length and leaf ratio of populations of Lythrum alatum and L. salicaria sampled in North America. Hardiness zone 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b. The Michigan Department of Natural Resources and the Michigan Agricultural Experiment Station provided funding for this project through the Wildlife Conservation and Restoration Act (Pittman–Robertson Project Number W-127-R). Lythrum salicaria var. Of 115 diagnostic characters identified in L. alatum, only two were clearly shown to have introgressed into L. salicaria. Batra SWT, Schroeder D, Boldt PD, Mendl W.

This plant has no children Legal Status. The unrooted neighbour-joining dendogram for 40 accessions in a survey of four sympatric and allopatric populations of Lythrum salicaria and L. alatum in Michigan. Winged Loosestrife Lythrum alatum Loosestrife family (Lythraceae) Description: This perennial plant is up to 3' tall, branching occasionally from the lower half of the central stem. Harsen's Island and Sheep Farm appeared to be more xeric than most other L. salicaria habitats, so it is possible that L. salicaria is evolving a more xeric ecotype, by re-assortment and selection of genes already available in its genome. National Plant Data Center, Baton Rouge, LA, USA. gracile DC., 1813 Lythrum salicaria var. Purple loosestrife, Lythrum salicaria, is a tall-growing wildflower that grows naturally on banks of streams and around ponds.It has strong, upright stems, from which long, poker-like heads of bright purple-red flowers appear from midsummer. The seller's sales listing, if you read, is Lythrum Alatum NOT Lythrum Salicaria.. Purple Loosestrife may be distinguished from other species of Lythrum by its stems that end in dense, showy flower spikes. Height: 24 to 60 inches (60 to 150 cm). Another 71 characters were found in only L. salicaria, and as a result could not have been derived from introgression. Naturalist 3: 265. This pattern supports introgression, but the character was also found in European L. salicaria and therefore could have been introduced. Variation in 64 AFLPs was analysed. Petals are textured like wrinkled tissue paper. 2011. Despite the same genus and similar comon name, Winged Loosestrife should not be confused with the non-native, invasive Purple Loosestrife (Lythrum salicaria) that threatens our North American wetlands. No L. salicaria from Asia or North Africa were examined. Winged Loosestrife can be found growing in the same wet-mesic prairies and meadows, fens, marshes and the borders of water bodies. The seller's sales listing, if you read, is Lythrum Alatum NOT Lythrum Salicaria.. Gray ex Rothr. Search for other works by this author on: Journal of the American Society of Horticultural Science, Proceedings of the Entomology Society Washington, Proceedings of the National Academy of Sciences of the USA, © The Author 2005. lanceolatum Lythrum alatum Pursh var. If sheared in mid-summer, new foliage generally will app… There also appears to be a strong environmental component to these characteristics, as most of the L. salicaria plants grown in the common greenhouse had leaf placement and flower numbers typical of L. salicaria, even though plants of both typical L. salicaria and typical L. alatum were collected in the field for use in this study. The stems are reddish-purple or red to purple and square in cross-section. 4B). Lythrum is a genus of 38 species of flowering plants native to the temperate world. Lythrum Alatum is a native of the US. Midl. Have you seen this plant in Minnesota, or have any other comments about it? Single flowers on short stalks blooming from each leaf axil, typically 2 to 5 blooming at a time in a cluster slowly ascending the branch as newer buds mature. Help support this site ~ Information for sponsor opportunities. Numbers along branches indicate bootstrap support for that branch (1000 replicates). Lower leaves are up to 2 inches long and ½ inch wide, more lance-like and opposite, becoming smaller, more oval and alternate in upper portions of the Stems are 4-sided, have slightly raised ridges or wings that run parallel the length of the stems, and are hairless. The PLANTS Database. The latter is an aggressive Eurasian plant that invades wetlands and forms dense stands that exclude other species. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Click on a place name to get a complete protected plant list for that location. Note that L. salicaria and L. alatum form well-separated clusters, and the North American L. salicaria are distinct from the cultivars and European L. salicaria. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. Its flowers are extremely attractive to bees and butterflies. The Atlas of Florida Plants provides a source of information for the distribution of plants within the state and taxonomic information. Again, only a few L. alatum genes must have been retained in the L. salicaria cultivar background, as only this one marker was consistent with introgression, and no visual morphological differences were observed between the cultivars and wild purple loosestrife populations. Found this in an Ag field that has been converted to a CREP easement. Lythrum salicaria Also known as Black Blood, Long Purples, Purple Grass, Rainbow Weed, Red Sally, Rose Loosestrife, Rosy Strip, Sage Willow, Soldiers, Spiked Loosestrife, Willow Weed, Purple Lythrum Common names are from state and federal lists. For info on subjects other than plant identification (gardening, invasive species control, edible plants, etc. Lythrum species Lythrum salicaria Name Synonyms Lythrum intermedium Ledeb. However, the number of L. alatum genes retained in L. salicaria is limited, suggesting that much of the adaptive switch in North American L. salicaria more likely came from the re-assortment and selection of genes within its own genome. See the glossary for icon descriptions. Lythrum salicaria is capable of invading a variety of wetland habitats, including marshes, river and stream banks, pond edges, lakes, road site ditches, and reservoirs. Some of these characters could have been transferred to North American L. salicaria via introgression with L. alatum, but because they were found in European L. salicaria, it is also possible that they were introduced from Europe. This species is not included in the IFBC key, but is described by Hitchcock and Cronquist (1973) as: Main leaves 3-10 cm, not cordate; petals purple, ca 5 mm; plants 4-10 dm. Lythrum alatum var. Variation in 279 AFLPs was evaluated. Life Cycle: Hardy perennial. Winged Loosestrife, Lythrum alatum is not the same as the botanical scourge, Purple Loosestrife, Lythrum salicaria. Nineteen AFLP characters were found in Michigan populations of both L. salicaria and L. alatum (Fig. Two L. salicaria populations (Harsen's Island and Sheep Farm) were intermediate in height and leaf ratio between the typical L. salicaria and L. alatum populations in both the native field and the common greenhouse. alatum winged lythrum Lythrum alatum var. Lythrum salicaria by Ettore Balocchi. & A. lanceolatum winged lythrum Legal Status. lanceolatum (Elliott) Torr. Crossing among genotypes from multiple introductions may have played an important role in the invasion of L. salicaria, through segregation of previously unassociated genes. Funding provided by the Minnesota Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources. Inaccurate comments hurt sellers. Please, research before posting negative comments. Likewise, L. salicaria and L. alatum were well differentiated within the sympatric populations. Plants may be sheared to the ground after flowering or if foliage becomes tattered from insect damage. If this volunteered in my garden I'd surely keep it. Description. The leaves are alternate in the upper half of the central stem and opposite from each other in the lower half; they are usually alternate in the smaller side stems. This is the expected pattern for a locus at which introgression occurred from L. alatum to L. salicaria. One character was found in North American L. alatum and in two of the cultivars, supporting a hybrid ancestry for them. It was brought to North America in the early 1800s through a number of pathways including The field populations of L. salicaria were generally taller and had longer, narrower leaves than those of L. alatum; however, four sympatric L. salicaria populations had mean heights significantly closer to typical L. alatum than typical L. salicaria (HIS, ONP, KIL and SFA), and leaf length in two of the sympatric L. salicaria populations (HIS and SFA) were much closer to the typical mean leaf length of … However, it is possible that the genes responsible were introduced from an unsampled part of the range of L. salicaria. Your Name: It was introduced to the United States as an ornamental plant. Thanks for your understanding. Minnesota Environment and Natural Resources Trust Fund, part shade, sun; along shores, wet meadows, wet prairies. The autopolyploid nature of L. salicaria may have facilitated its adaptation to new habitats in North America, as the increased levels of heterozygosity generally observed in polyploids may have pre-adapted L. salicaria with sufficient plasticity to fill many habitats, and these high levels of allelic diversity were available for re-assortment after hybridization via tetrasomic inheritance. Within the L. salicaria cluster, the introduced North American L. salicaria form a distinct terminal cluster that appears to be derived from within the larger cluster containing the cultivars and the European L. salicaria. A plant has several racemes on erect branching stems in the upper part of the plant.
