Ludwigia erecta, commonly known as the upright primrose-willow, is an annual herbaceous plant that typically grows as an erect, highly branched herb reaching heights between 1 and 3 metres. During its flowering season the plant produces solitary yellow flowers in the upper leaf axils, each featuring four petals and eight stamens. Primarily found in tropical and subtropical regions of the Americas, it thrives in wet environments such as marshes, swamps, and ditches, where its square, four-angled capsules eventually release numerous tiny seeds.
Description
• Ludwigia erecta, commonly known as yerba de jicotea or primrose, is an erect, branching annual herb in the evening primrose family (Onagraceae). It can grow from about 30 centimetres to over 1 metre tall, with angular stems that may be tinged reddish. Its alternate leaves are narrow oval to lance-shaped, with smooth margins and pointed tips. Small, four-petalled yellow flowers grow singly in the leaf axils. The fruit is an elongated, four-angled capsule containing numerous tiny seeds.
Range
• Ludwigia erecta is native to the Americas, ranging from the southern United States through Mexico, Central America, and the Caribbean to much of South America, including Brazil and Paraguay. It is native to Zihuatanejo, Guerrero, and the surrounding area.
Habitat
• It grows in wet or seasonally waterlogged habitats, including marshes, pond margins, riverbanks, drainage ditches, muddy clearings, and other moist, disturbed areas. It is often found in open, sunny sites with saturated soils and can grow in shallow standing water or on exposed mud.
