Hit

The deceptive evening primrose ( Oenothera × fallax ), also known as the deceptive evening primrose or bastard evening primrose , is a species of the evening primrose genus ( Oenothera ) in the evening primrose family (Onagraceae) that has emerged in Europe . It is probably a hybrid between the red-goblet evening primrose ( Oenothera glazioviana ) and the common evening primrose ( Oenothera biennis ).

description

The Deceptive Evening Primrose is a biennial plant with a stature height of 0.8 to 1.6 meters. Long bristly and shorter curved hairs are formed on the stem and flower stalk. The base of the bristly hair is red, so that the stems and flower stalks are spotted with red. The 10 to 15 cm long and 2 to 3 cm wide leaves have an elliptical to ovate-lanceolate leaf blade. The central rib of the leaf is strikingly white or red in color. The leaf margin is serrated, the lower stem leaves are wavy.

The calyx tube is 30 to 40 mm long. The yellow petals are (15 to) 20 to 30 mm long and 18 (22) to 34 mm wide. A capsule fruit 20 to 30 mm long is formed.

The number of chromosomes is 2n = 14.

Occurrence

The Deceptive Evening Primrose is a hybrid of the red-goblet evening primrose ( Oenothera glazioviana ) and the common evening primrose ( Oenothera biennis ) that emerged spontaneously in Central Europe . It is common throughout Central Europe. In Germany it is one of the most common types of evening primrose.

It grows ruderally in the early phases of vegetation development on open ground, for example at roadsides, at railway and ship ports, industrial or fallow land. The ruderal corridors , in which it mostly grows dominantly, are characterized by bee plants and, in terms of plant sociology, belong to the donkey thistle corridors .

Systematics

The deceptive evening primrose ( Oenothera × fallax ) is probably a hybrid between the red-goblet evening primrose ( Oenothera glazioviana Micheli ) and the common evening primrose ( Oenothera biennis L. ). Synonyms for Oenothera × fallax Renner are Oenothera coloratissima Hudziok and Oenothera × oehlkersii Kappus ex Rostanski .
