Purple loosestrife (Lythrum salicaria) is listed as a noxious weed in nearly every state in the U.S, and is therefore illegal to sell, buy, trade or transport. Reed canary grass is present and expanding. lanceolatum (Elliott) Torr. Two hundred and seventy-nine characters could be assorted into four categories based on their evolutionary pattern in the NJ tree. Thanks for your understanding. In the individual examination of each of the 64 AFLP characters in the global data, 16 AFLP markers were found in only L. salicaria. salicaria Homonyms Lythrum salicaria L. Common names (pohjan)rantakukka in Finnish Gray ex Rothr. Of 115 diagnostic characters identified in L. alatum, only two were clearly shown to have introgressed into L. salicaria. 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. Lythrum alatum aka Winged Loosestrife. Another 71 characters were found in only L. salicaria, and as a result could not have been derived from introgression. Hardiness zone 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b. 4B).

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. It was introduced to the United States as an ornamental plant. This central stem is strongly winged and hairless. Numbers along branches indicate bootstrap support for that branch (1000 replicates). This indicates that these cultivars have not extensively hybridized with North American L. salicaria, and the integrity of the cultivars in nursery stock remains. One character was found in North American L. alatum and in two of the cultivars, supporting a hybrid ancestry for them. Several scattered patches were found in a former agriculture field that is converting to wet meadow. Purple Loosestrife (Lythrum salicaria) 1 Introduction Purple loosestrife (Lythrum salicaria L.) is an invasive, emergent, perennial plant, native to Europe and Asia. 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). Lythrum Alatum is a native of the US. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees, flies. In states where they may be grown legally, they should be sited in medium to wet soils in full sun to light shade. Stems are 4-sided, have slightly raised ridges or wings that run parallel the length of the stems, and are hairless. It is noted for attracting wildlife. 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. 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. All rights reserved. long (45 cm) held atop lance-shaped leaves. I have some winged loosestrife that has shown up in my garden-should I keep it? National Plant Data Center, Baton Rouge, LA, USA. – winged lythrum Subordinate Taxa.

It was brought to North America in the early 1800s through a number of pathways including Description. Your Name: Ten AFLP characters were identified in L. alatum but not in European L. salicaria. Common Name(s): purple lythrum [English] rainbow weed [English] spiked loosestrife [English] purple loosestrife [English] Taxonomic Status: … AFLP characters shared by Michigan populations of L. alatum and L. salicaria. Individual flowers are ¼ to ½ inch across with 6 petals, pale lavender, purple or rose-pink with a darker mid-vein, rounded at the tip and fused at the base into a short tube, forming an off-white throat. 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. lanceolatum Lythrum alatum Pursh var. Likewise, L. salicaria and L. alatum were well differentiated within the sympatric populations. Pick an image for a larger view. It features pink, purple or magenta flowers in dense spikes, up to 18 in. This pattern supports introgression, but the character was also found in European L. salicaria and therefore could have been introduced. The latter is an aggressive Eurasian plant that invades wetlands and forms dense stands that exclude other species. It is hardy to zone (UK) 3. 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. Numbers along branches indicate bootstrap support for that branch (1000 replicates). Common names are from state and federal lists. The characters evaluated here are probably good representatives of the various taxa examined, as they clearly distinguished them in the phylogenetic analysis.

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. 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. 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. Naturalist 3: 265. Its flowers are extremely attractive to bees and butterflies. 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. 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. 2. Purple Loosestrife may be distinguished from other species of Lythrum by its stems that end in dense, showy flower spikes. Web design and content copyright © 2006-2020 MinnesotaWildflowers.info. Found still blooming on Aug 10 at Iron Horse prairie SNA. Flower Color is and blooms in . 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 salicaria var. The Purple Loosestrife flower inhabits reed swamps, margins of lakes and slow-flowing rivers, ditches and marshes. Life Cycle: Hardy perennial. & A. 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. couldn't find them in any of my reference books. The unrooted neighbour-joining dendogram for 71 accessions in a global survey of Lythrum salicaria and L. alatum in North America and Europe. & A. 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. This native plant should not be confused with Lythrum salicaria (Purple Loosestrife). 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. Love your site. Strefeler MS, Darmo E, Becker RL, Katovich EJ. 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. lanceolatum (Elliott) Torr. Map of native plant purveyors in the upper midwest, Photos courtesy Peter M. Dziuk taken in Dodge County. 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. 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. Lythrum species Lythrum salicaria Name Synonyms Lythrum intermedium Ledeb.

The seller's sales listing, if you read, is Lythrum Alatum NOT Lythrum Salicaria.. The molecular data indicate that introgression may have occurred between the two North American Lythrum species, although the number of genes incorporated into the genome of L. salicaria appears to be limited. Leaves are elliptical to lance-shaped, rounded at the base and tapered to a Variation in 279 AFLPs was evaluated. 2011. plant. Minnesota Environment and Natural Resources Trust Fund, part shade, sun; along shores, wet meadows, wet prairies. It can spread through seeds when cross-pollinated with other Lythrum species or through rooting stem fragments. Where in Minnesota? alatum winged lythrum Lythrum alatum var. Whether hybridization with L. alatum (winged loosestrife) could have played a role in its ultimate spread was tested. This is the expected pattern for a locus at which introgression occurred from L. alatum to L. salicaria. Lythrum salicaria by Ettore Balocchi. 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. 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).

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. Sakai AK, Allendorf FW, Holt JS, Lodge DM, Molofsky J, With KA, et al. Once established, however, L. salicaria can exist in a wide range of soil types. 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 … 1914, non Sessé y Lacasta & Moçiño 1888. Batra SWT, Schroeder D, Boldt PD, Mendl W. Mack RN, Simberloff D, Lonsdale WM, Evans H, Cout M, Bazzaz FA. The stems are reddish-purple or red to purple and square in cross-section.

Lythrum alatum var. 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. Growing alongside Valley Redtsem (Lythraceae) in a muddy patch that had ponding due to wet springs. Sixty-six characters were fixed in both species, so could not be used to evaluate whether introgression had occurred. 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. Variation in 64 AFLPs was analysed. Saw these along the sidewalk near the visitors entrance. Have never come across it before- super cute plant! However, it is possible that the genes responsible were introduced from an unsampled part of the range of L. salicaria. Lythrum alatum - Winged Loosestrife by bob in swamp. Plants may be sheared to the ground after flowering or if foliage becomes tattered from insect damage. Grows in Sun to Part Sun. It was introduced to the United States and Canada as an ornamental for wetlands in the 1800s. It is possible that all the Michigan L. salicaria were fixed for the other 19 traits because of an ancient introgression resulting in a single Michigan founder, but this is deemed unlikely because L. salicaria carries so much genetic variability in Michigan. Gray ex Rothr. View a photo. ), please check the links and invasive species pages for additional resources. Flowering spikes should be deadheaded immediately after bloom to prevent self-seeding. 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. The plant prefers moist soil with neutral to slightly acidic pH. The lance-shaped leaves are up to 4 inches long, and mostly opposite or in whorls of 3 (which may appear alternately arranged). Lythrum Plant Growing and Care Guide. Note that L. salicaria (below) and L. alatum (above) form distinct clusters. Lythrum alatum var. Please, research before posting negative comments.

Petals are textured like wrinkled tissue paper. It is in flower from June to August, and the seeds ripen from August to September. Winged Loosestrife is the native next of kin to the widely invasive and destructive Purple Loosestrife, Lythrum salicaria that was introduced by gardeners via the global nursery industry and is now ranked among the most highly problematic invasive species in North America. For info on subjects other than plant identification (gardening, invasive species control, edible plants, etc. Lythrum is a genus of 38 species of flowering plants native to the temperate world. 6 purplish brown stamens extend out of the throat with the single greenish style hidden inside the tube. 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. Lythrum alatum Pursh – winged lythrum Variety: Lythrum alatum Pursh var. 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. The calyx holding the flower forms a narrow tube and has strong parallel veination and 6 sharp tips curved outward. It infests waterways across the entire continental U.S. (with the exception of Florida below the panhandle) and Canada below the Arctic Circle. Found this in an Ag field that has been converted to a CREP easement. Winged Loosestrife, Lythrum alatum is not the same as the botanical scourge, Purple Loosestrife, Lythrum salicaria. All of the cultivars, including the apparent introgressants Morden's Gleam and Happy, grouped more closely with European L. salicaria than North American L. salicaria or L. alatum. ex Colla Lythrum salicaria var. Lythrum Alatum is a native of the US. In the study of sympatric and allopatric populations in Michigan, these three characters were found in all L. alatum and at least some individuals of all L. salicaria populations (Table 4). (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. The unrooted NJ dendrogram for the 71 accessions in the global data set is shown in Fig. If sheared in mid-summer, new foliage generally will app… Commonly known as loosestrife (a name they share with Lysimachia, which are not closely related), they are among 32 genera of the family Lythraceae. Winged Loosestrife, Lythrum alatum is not the same as the botanical scourge, Purple Loosestrife, Lythrum salicaria. tomentosum (Mill.) 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. Purple Loosestrife (Lythrum Salicaria Rosy Gem) - This attractive perennial produces a showy display of carmine-colored flower spikes throughout much of the summer. Lythrum salicaria is a PERENNIAL growing to 1 m (3ft 3in) by 0.5 m (1ft 8in) at a fast rate. 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.

These characters could not have been acquired by L. salicaria through introgression with L. alatum because they are not in L. alatum. 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 Location and mean plant height, leaf length and leaf ratio of populations of Lythrum alatum and L. salicaria sampled in North America. 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. Synonym Full Citation Basionym Type; Lythrum cordifolium Lythrum cordifolium Nieuwland, Amer. 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 The PLANTS Database. Height: 24 to 60 inches (60 to 150 cm). Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. 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 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. Midl. Very similar to the more commonly known purple loosestrife (Lythrum salicaria), wanded loosestrife is a European wetland plant that has been introduced to North America and widely sold as an ornamental.Plants grow 3-4 feet tall with showy pink to purple flowers on four-angled stems. Its flowers are extremely attractive to bees and butterflies. Nineteen AFLP characters were found in Michigan populations of both L. salicaria and L. alatum (Fig. DC. Lythrum salicaria and L. alatum also formed distinct and well-separated clusters in the unrooted NJ dendogram using the Michigan AFLP data set (Fig. 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. This plant has no children Legal Status. One hundred and twenty-three characters were found in L. alatum but not in L. salicaria, which also does not support introgression. 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. 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. They may not be sold in commerce and, if currently growing, must be controlled. The website also provides access to a database and images of herbarium specimens found at the University of South Florida and other herbaria. lanceolatum winged lythrum Legal Status. 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.
