Minnesota Environment and Natural Resources Trust Fund, part shade, sun; along shores, wet meadows, wet prairies. Ten AFLP characters were identified in L. alatum but not in European L. salicaria. 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 Lythrum species Lythrum salicaria Name Synonyms Lythrum intermedium Ledeb. No L. salicaria from Asia or North Africa were examined. Purple Loosestrife may be distinguished from other species of Lythrum by its stems that end in dense, showy flower spikes. This is the expected pattern for a locus at which introgression occurred from L. alatum to L. salicaria. The unrooted neighbour-joining dendogram for 71 accessions in a global survey of Lythrum salicaria and L. alatum in North America and Europe. Abstract • Background and Aims Although Lythrum salicaria (purple loosestrife) was introduced to North America from Europe in the early 1800s, it did not become invasive until the 1930s. The seller's sales listing, if you read, is Lythrum Alatum NOT Lythrum Salicaria.. Grows in Sun to Part Sun. The latter is an aggressive Eurasian plant that invades wetlands and forms dense stands that exclude other species. The PLANTS Database. Your email address: (required) & A. The stems are reddish-purple or red to purple and square in cross-section. Variation in 279 AFLPs was evaluated. It can spread through seeds when cross-pollinated with other Lythrum species or through rooting stem fragments. Crossing among genotypes from multiple introductions may have played an important role in the invasion of L. salicaria, through segregation of previously unassociated genes. 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. United States Department of Agriculture, Natural Resource Conservation Service. 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. Lythrum salicaria var. I have some winged loosestrife that has shown up in my garden-should I keep it? Individual patterns of AFLP variation in the Michigan survey of allopatric and sympatric populations of North American Lythrum salicaria and L. alatum. 4B). View a photo. Winged Loosestrife, Lythrum alatum is not the same as the botanical scourge, Purple Loosestrife, Lythrum salicaria. thanks to you, the problem is solved! The characters evaluated here are probably good representatives of the various taxa examined, as they clearly distinguished them in the phylogenetic analysis. However, it is possible that the genes responsible were introduced from an unsampled part of the range of L. salicaria. Found this in an Ag field that has been converted to a CREP easement. Plants may be sheared to the ground after flowering or if foliage becomes tattered from insect damage. 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. This central stem is strongly winged and hairless. ), please check the links and invasive species pages for additional resources. Please, research before posting negative comments. Pick an image for a larger view. 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. Height: 24 to 60 inches (60 to 150 cm). Lythrum Plant Growing and Care Guide. Where in Minnesota? Lythrum salicaria and L. alatum also formed distinct and well-separated clusters in the unrooted NJ dendogram using the Michigan AFLP data set (Fig. Petals are textured like wrinkled tissue paper. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. The website also provides access to a database and images of herbarium specimens found at the University of South Florida and other herbaria. If this volunteered in my garden I'd surely keep it. Numbers along branches indicate bootstrap support for that branch (1000 replicates). Location and mean plant height, leaf length and leaf ratio of populations of Lythrum alatum and L. salicaria sampled in North America.

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 Naturalist 3: 265. 1914, non Sessé y Lacasta & Moçiño 1888. Map of native plant purveyors in the upper midwest, Photos courtesy Peter M. Dziuk taken in Dodge County. 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). It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Please, research before posting negative comments. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. The unrooted NJ dendrogram for the 71 accessions in the global data set is shown in Fig. Life Cycle: Hardy perennial. Leaves are elliptical to lance-shaped, rounded at the base and tapered to a Of 115 diagnostic characters identified in L. alatum, only two were clearly shown to have introgressed into L. salicaria. gracile DC., 1813 Lythrum salicaria var. It appears that L. alatum contributed some unique genes to L. salicaria through introgression, and this could have played a role in L. salicaria becoming more invasive in North America than in Eurasia. 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. Numbers along branches indicate bootstrap support for that branch (1000 replicates). 2011. tomentosum (Mill.) One character was found in North American L. alatum and in two of the cultivars, supporting a hybrid ancestry for them. plant. Twenty-seven characters were shared by L. alatum and L. salicaria in a broad sense, with bands both in L. alatum and in either European populations or both the European and the native North American populations. It is hardy to zone (UK) 3. Web design and content copyright © 2006-2020 MinnesotaWildflowers.info. 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. Purple Loosestrife (Lythrum salicaria) 1 Introduction Purple loosestrife (Lythrum salicaria L.) is an invasive, emergent, perennial plant, native to Europe and Asia. DC. Spectacular when in full bloom, Purple Loosestrife (Lythrum salicaria) is a vigorous, upright perennial enjoying an extremely long bloom season from late spring to late summer. Your Name: All rights reserved. alatum winged lythrum Lythrum alatum var. 3). Lythrum salicaria is a PERENNIAL growing to 1 m (3ft 3in) by 0.5 m (1ft 8in) at a fast rate. Comment (max 1000 characters): Note: Comments or information about plants outside of Minnesota and neighboring states may not be posted because I�d like to keep the focus of this web site centered on Minnesota. Batra SWT, Schroeder D, Boldt PD, Mendl W. Mack RN, Simberloff D, Lonsdale WM, Evans H, Cout M, Bazzaz FA. 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 is a native of the US. It was introduced to the United States and Canada as an ornamental for wetlands in the 1800s. Of these, eight were found only in L. alatum in North America and as a result had not been transferred to L. salicaria via hybridization. 6 purplish brown stamens extend out of the throat with the single greenish style hidden inside the tube. Lythrum salicaria by Ettore Balocchi. Inaccurate comments hurt sellers. 2. It was brought to North America in the early 1800s through a number of pathways including They may not be sold in commerce and, if currently growing, must be controlled. This plant has no children Legal Status. gracilior Turcz. – winged lythrum Subordinate Taxa. Purple Loosestrife (Lythrum Salicaria Rosy Gem) - This attractive perennial produces a showy display of carmine-colored flower spikes throughout much of the summer. It is in flower from June to August, and the seeds ripen from August to September. 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. Help support this site ~ Information for sponsor opportunities. Lythrum alatum aka Winged Loosestrife. This indicates that these cultivars have not extensively hybridized with North American L. salicaria, and the integrity of the cultivars in nursery stock remains. In the individual examination of each of the 64 AFLP characters in the global data, 16 AFLP markers were found in only L. salicaria. lanceolatum (Elliott) Torr. Love your site. 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. Likewise, L. salicaria and L. alatum were well differentiated within the sympatric populations. 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. Purple loosestrife, Lythrum salicaria, is a tall-growing wildflower that grows naturally on banks of streams and around ponds.It has strong, upright stems, topped in summer with long, poker-like heads of bright purple-red flowers. 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. 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. Lythrum alatum var. See Terms of Use and Privacy Policy. Note that L. salicaria (below) and L. alatum (above) form distinct clusters. One hundred and twenty-three characters were found in L. alatum but not in L. salicaria, which also does not support introgression. 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. Lythrum is a genus of 38 species of flowering plants native to the temperate world. 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. This suggests that breeders have hybridized the two species in their cultivar development efforts, although the reported hybrid Morton Rose did not carry this fragment. 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. It infests waterways across the entire continental U.S. (with the exception of Florida below the panhandle) and Canada below the Arctic Circle. Winged Loosestrife, Lythrum alatum is not the same as the botanical scourge, Purple Loosestrife, Lythrum salicaria. Strefeler MS, Darmo E, Becker RL, Katovich EJ. This native plant should not be confused with Lythrum salicaria (Purple Loosestrife). Sakai AK, Allendorf FW, Holt JS, Lodge DM, Molofsky J, With KA, et al. 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. 05 (LSD test). The lance-shaped leaves are up to 4 inches long, and mostly opposite or in whorls of 3 (which may appear alternately arranged). Common names are from state and federal lists. The Purple Loosestrife flower inhabits reed swamps, margins of lakes and slow-flowing rivers, ditches and marshes. Reed canary grass is present and expanding.
