Page: 1 (revision date:4/7/2021) Weeds: Purple deadnettle (Red deadnettle)(Lamium purpureum) family: Lamiaceae (Labiatae) cycle Annual plant type: Broadleaf Use Integrated Pest Management (IPM) for successful plant problem management. Biology Purple deadnettle has the square stems and opposite leaves characteristic of most plants in the mint family. Plants usually branch from the spreading base. Leaves mostly occur near the top of the branches, which are up to a foot tall. Branches may root at the lower nodes. Leaves (up to nearly one inch long) are all somewhat hairy, but never shiny. The lower leaves have long petioles, while the upper leaves have very short petioles (but do not surround or clasp the stem). Upper leaves may be densely crowded and have a purplish to reddish appearance. The flowers are pink to purplish, appearing in whorls in the axils of the upper leaves. Purple deadnettle may sometimes be confused with henbit (Lamium amplexicaule), but the upper leaves of henbit clasp the stem and are not hairy, and leaf pairs are more widely spaced on the stem. Habitat Purple deadnettle occurs in gardens, fields, and other cultivated areas, typically on rich soils.

Research Regarding the Melliferous Charactheristics of Labiates from Xerophile Meadows from Danube Valley
Lucr ări ştiin Ńifice Zootehnie şi Biotehnologii , vol. 41(1) (2008 ), Timi şoara RESEARCH REGARDING THE MELLIFEROUS CHARACTHERISTICS OF LABIATES FROM XEROPHILE MEADOWS FROM DANUBE VALLEY CERCET ĂRI ASUPRA VALORII MELIFERE A LAMIACEELOR DIN PAJI ŞTILE XEROFITE DIN LUNCA DUN ĂRII ION NICOLETA Apiculture Research and Development Institute of Bucharest, Romania The xerophile meadows in the Danube Valley are dry meadows, located at a great distance from the Danube and with underground waters at greater depth. Their floral composition is characterized by a small number of species pertaining to both mezoxerophiles and to xerophiles, yet the highest percentage is covered by xerophile species, which are characterized by their small foliage surface, the very narrow and tough limb, and acute porosity etc.In the floral composition of these species, the graminaceae species are best represented, followed by leguminous and lamiaceae, known in beekeeping as good honey plants. Thus, the researches carried out have shown that Lamiaceae species have a good participation, with variation limits raging from 15% to 50-60%. Leguminous species are represented less on xerophile meadows than in hidrophile meadows. Among these we mention: Lotus corniculatus L., Trifolium repens L. şi Medicago lupulina L., all these species being known in beekeeping as good honey plants. Among gramineae species the most representatives are: Lolium perene L. and Poa pratensis L., yet with no melliferous value. Likewise, the group of „various” plants varied a lot as participation in the structure of the vegetal cover of xerophile meadows, depending on the place of research, all these species having no melliferous value. The current paper describes the results o biometric and melliferous researches carried out over the period 2003- 2005 on 5 plant species pertaining to the Lamiaceae family, namely: Salvia nemerosa L.

The Herbaceous Vascular Plants of Blackacre Preserve a Preliminary List II Additions for 2011 Season
The Herbaceous Vascular Plants of Blackacre Preserve A Preliminary List II Additions for 2011 Season December 8, 2011 Submitted to: Kentucky State Nature Preserves Commission Submitted by: William E. Thomas Herbarium Indiana University Southeast Photo: Purple Rocket by Richard Lyons 1 Scope The goal of this survey was to compile a rough list of herbaceous vascular plant species on the below described tract. The survey was conducted from July 11, 2010 through the end of the growing season in 2011. This report is the second of the survey and augments the first report of December 2010 by adding many of the spring ephemerals which were missed due to the late start in the 2010 season. Any extensive populations of invasive alien species were noted as well. Locale Description The Blackacre Preserve website states that the property consists of 170 acres in eastern Jefferson County Kentucky. It is the authors understanding that some additional acreage (size?) was appended to the southern border of the original 170 acre tract. The property is located at 3200 Tucker Station Rd. The tract is bordered on all sides by housing and urban areas; a railroad track runs along the north border. The terrain is of mostly gentle slopes with some wooded areas and open fields formerly used for pasture or crops. There are several ponds on the property; a limestone glade area constitutes the northeast corner of the tract. A small creek flows east to west across the tract north of the center. There are numerous foot trails, some designated and some rogue. An old section of Mann’s Lick road runs northward about midway in the tract.

Interaction of Purple Deadnettle, Lamium Purpureum, Soybean
INTERACTION OF PURPLE DEADNETTLE, LAMIUM PURPUREUM, SOYBEAN CYST NEMATODE, HETERODERA GLYCINES AND ITALIAN RYEGRASS, LOLIUM MULTIFLORUM Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Bruce Austin Ackley Graduate Program in Horticulture and Crop Science The Ohio State University 2013 Committee: Dr. Kent Harrison, Advisor Dr. Mark Sulc, Advisor Dr. Emilie Regnier Copyrighted by Bruce Austin Ackley 2013 Abstract Soybean cyst nematode (SCN; Heterodera glycines) causes more economic damage to U.S. soybean producers than any other soybean pathogen. Greenhouse and field studies have shown that the winter annual weed purple deadnettle (PDN) is an alternate host of SCN. Previous work has shown that Italian ryegrass significantly reduced SCN populations in soil under greenhouse and field conditions, but the nature and extent of this suppressive effect on SCN is not well understood. My research focused on investigating the nature of the Italian ryegrass x SCN interaction and the effectiveness of Italian ryegrass as a winter cover crop to suppress SCN and PDN. The first study was conducted in the greenhouse and consisted of a replacement pot experiment in which plant biomass and SCN reproduction was measured from pots containing various ratios of Italian ryegrass (IR) and PDN, +SCN. The second study was conducted at Waterman Agricultural and Natural Resource Laboratory of The Ohio State University, Columbus, OH in SCN infested field microplots and was designed to duplicate treatments investigated in the greenhouse with the addition of other forage species. The studies focused on the dual ability of Italian ryegrass to provide suppression of PDN and reduce SCN populations.

New York City Ecoflora
New York City EcoFlora Lamium (Lamiaceae, Mint Family) Deadnettle Description: Herbs, annual or perennial, aromatic or foetid. Leaves opposite, usually ovate or reniform, the margins crenate or toothed, the bases usually cordate, upper leaves usually crowded, short-petiolate. Flowers sessile (or nearly so) in verticels of clustered cymes, cleistogamous flowers sometimes present; calyx tubular to campanulate, sharp-toothed; corolla, pink, purple, white or yellow, the tube usually longer than the calyx, 2-lipped, the upper hooded, the lower 3-lobed; stamens 4, in 2 pairs, ascendant under the upper corolla lobe, not exserted, the anthers ciliate. Fruit a schizocarp of 2–4 nutlets. Where Found: The genus is native to Europe, Asia and North Africa and is naturalized in North America. The "weedy" annual species are adapted to disturbed sites in urban and agricultural areas. Natural History: Henbit (Lamium amplexicaule), Deadnettle (Lamium purpureum) and Cut-Leaved Deadnettle (Lamium hybridum) are winter-annuals that germinate in the fall and overwinter as small plants, often going unnoticed in the landscape. As the weather warms in spring, they grow vigorously, flower and set seed before the heat of summer, germinating in fall and starting the process over. Other common winter annuals in our area include Chickweed (Stellaria media), Mustards (Brassica spp., Barbaraea vulgaris, Capsella bursa-pastoris), Bedstraw (Galium spp.), Sow-Thistles (Sonchus spp.), Prickly Lettuce (Lactuca serriola), Persian Speedwell (Veronica persica) and the native Common Horseweed (Erigeron canadensis var. canadensis). Many winter-annuals are autogamous, a reproductive strategy common to short-lived species in unpredictable circumstances. These species are typically self-fertile and sometimes the flowers don't even open (cleistogamous).

In foraging for nectar, animals carry out the amino acids whilst plants pollinated by birds exhibit vital role of pollination. Many animal taxa visit flowers, but the low concentrations of amino acids (Baker and Baker most abundant pollinators are insects. Although amino acids are 1973, Baker 1982). The ecological rationale underlying detectable by insects, little work has focussed on the role of taste this is that butterflies are specialized liquid feeders as in the ecology of pollination (with most studies concentrating on foraging choice).
