Die Großblütige Vogel-Sternmiere (Stellaria neglecta), auch Auwald-Sternmiere genannt, ist eine Pflanzenart der Familie der Nelkengewächse (Caryophyllaceae).
Die einjährige krautige Pflanze erreicht eine Länge von etwa 20 bis 80 cm. Der Stängel ist einreihig behaart. Sie ist eng mit der Vogel-Sternmiere verwandt und ähnelt ihr im Habitus. Die Laubblätter sind eiförmig, kurz zugespitzt, die unteren mehr oder weniger gestielt und können bis zu 4 cm lang werden.
Die Blütenstiele sind kahl oder ringsum weichhaarig. Die Kronblätter sind weiß und so lang oder etwas länger als der Kelch. Die Kelchblätter sind mehr oder weniger stumpflich und 5 bis 6,5 mm lang. Diese Art besitzt in der Regel zehn purpurrote Staubbeutel. Sie blüht von April bis Juli.
Die Samen haben eine Größe von 1,3 bis 1,7 mm, sind dunkel-rotbraun und besitzen vier Reihen hohe, spitzkegelige Warzen.
Die Chromosomenzahl beträgt 2n = 22.[1]

Die Großblütige Vogel-Sternmiere wächst in Waldsaum-Gesellschaften, an Waldwegen und in Unkrautfluren. Sie bevorzugt feuchte, nährstoffreiche Sand- und Lehmböden.
Die Verbreitung von Stellaria neglecta ist noch ungenügend bekannt. Sie ist wohl ein subatlantisch-submediterranes Florenelement.
In Österreich kommt sie zerstreut bis selten vor, in der Schweiz wächst sie allgemein zerstreut.
Die Großblütige Vogel-Sternmiere kommt in der Mitte und im Norden Deutschlands zerstreut bis selten vor. Darüber hinaus ist sie sehr selten zu finden.
Die Art wurde früher als Unterart der Vogel-Sternmiere (Stellaria media) angesehen und als Stellaria media ssp. neglecta (Weihe) Gremli bezeichnet.
Die Großblütige Vogel-Sternmiere (Stellaria neglecta), auch Auwald-Sternmiere genannt, ist eine Pflanzenart der Familie der Nelkengewächse (Caryophyllaceae).
Stellaria neglecta, greater chickweed, is an annual to short-lived herbaceous perennial flowering plant in the family Caryophyllaceae. It is native to Europe and Asia, where it grows in hedges and woodland margins on neutral to slightly acid, damp soils, and is widespread but rarely abundant. It has been introduced to North America, where it has been spreading in recent decades.
A sprawling annual (to short-lived perennial) with weak branching stems that are usually decumbent at the base, ascending distally to around 80–90 cm, often supported by other plants. The stems are cylindrical and glabrous except for a single line of hairs that runs lengthways, changing sides at each node. Other parts of the plant are usually entirely glabrous. The leaves are arranged in opposite pairs, the lower ones having long (2-5 cm), narrowly-winged stalks and a broadly oval-triangular blade about 3 cm long by 1.5 cm wide. The upper leaves are sessile or only very shortly petiolate, and slightly larger are more oval. The leaves have one strong central vein along the midrib and about 5 lateral veins on each side.[1][2][3]
The flowers are borne singly in the uppermost leaf axils on slender 2-3 cm stalks, initially spreading and reflexed, later erect. Each flower has five sepals, 5−6.5 mm long, lanceolate, glabrous or rarely pubescent, with an acute apex. There are also five white petals which are divided almost to the base, giving the impression that there are ten. The petals are usually just slightly shorter than the sepals, the whole flower being about 10 mm in diameter. There are 8-10 reddish stamens and three styles.[4][1][3][5]
It flowers between April and July in Northern Europe.[1] The stems can remain alive and produce tillers which overwinter and flower the following year.[4] Seeds are tuberculate, dark reddish-brown, 1.3−1.7 mm in diameter.[1] The tubercles are conical, with an acute apex.[3]
This species was first published by Alexandre Louis Simon Lejeune in 1825 as Alsine neglecta, which is therefore the basionym. It was then (the same year) moved to the genus Stellaria L. by Carl Ernst August Weihe and this name is accepted to this day.[6] Over the years many synonyms have been coined, such as Alsine decandra Schur (in 1866), Stellaria media var. decandra Fenzl (in 1842) and Stellaria decandra Schur ex Prodan (in 1953). A full list is given by the Synonymic Checklists of the Vascular Plants of the World.[7]
Numerous subspecies, varieties and forms have been named, but none is currently accepted[7] and it is not known to hybridise with any other species.[8]
Its chromosome number is 2n = 22.[5]
The scientific name Stellaria means "like a star" in reference to the flowers, and neglecta is in acknowledgement that it was long overlooked,[9] something that is still true to this day.[10]
Three species of chickweed have a single line of hairs down the stem. There are various features which can be used to separate them: Stellaria apetala usually has 1-3 stamens and no white petals; S. media has 3-8 stamens and white petals up to 3 mm long; whereas S. neglecta usually has 10 stamens and petals up to 4 mm. As the anthers often fall off, it is best to count the filaments.[5][11]
In the absence of flowers, the size of the plants (up to 10 cm; 25 cm; 100 cm) is a useful character, as are the leaves (up to 7 mm; 25 mm; 50 mm respectively), which also look rather different on the various species.[2]
Greater chickweed is widely distributed throughout Europe and southern Asia as far east as Japan.[7][12] In Great Britain, it is most common in the south and west.[13] In North America, it was formerly rare, but it has spread rapidly in recent decades and is now considered a weed in a number of states, from Maryland to California.[3]
The international status of greater chickweed has not been evaluated,[14] but in Britain it is classified as "Least Concern" on the grounds that it is still widespread, albeit declining.[15][10] In France it is similarly not threatened except in the Alsace region, where it is considered to be vulnerable.[16]
Greater chickweed grows in lightly shaded situations on slightly damp, base-rich and moderately fertile soils. Its Ellenberg values in Britain are L = 6, F = 7, R = 6, N = 7, and S = 0.[17] It is often found in old hedges and on the margins and paths of ancient deciduous woodland, where it is generally sparsely distributed and tends to occur in small patches.[18][19]
In terms of the British National Vegetation Classification it is recorded in MG1 false oatgrass swards on woodland edges, W6 crack willow woodland by rivers, in W10 oak woodland and W24 bramble scrub in hedges.[19] Because it is quite scarce and declining, and largely restricted to old hedges and woods, it is considered an axiophyte in some counties.[20][19]
It is a lowland plant, reaching its altitudinal limit of 345 m in Britain on Stapeley Hill in Shropshire.[21]
Presumably because it is such a little-known plant, there are no recorded instances of insect associations with this species in Britain.[22] There are also no known galls, rusts or smuts.[23]

De plant wordt 30 - 80 cm hoog. De eenrijig behaarde stengel is evenals de bloeiwijzetakken rond. De tot 5 cm lange bladeren zijn eirond met een korte spits. De onderste bladeren zijn gesteeld en kunnen tot 4 cm lang worden.
Heggenvogelmuur bloeit in april en mei met witte, 10 mm grote bloemen. De kroonbladen zijn meestal langer dan de 5 - 6,5 mm lange kelkbladen. De bloem heeft meestal tien meeldraden met purperrode helmhokjes.
De vrucht is een eenhokkige doosvrucht. De donker-roodbruine zaden zijn 1,1 - 1,7 mm lang en hebben vier rijen hoge spitskegelvormige wratten.
