|Common Names||English: Hairy galinsoga, shaggy soldier; German: Zottiges Franzosenkraut, Behaartes Franzosenkraut; French: Galinsoga cilié|
|Description||Seed-producing summer annual weed, 15 to 60 cm (5.9 - 23.62 inch) high, originates from Peru, came to Germany from France.|
Small, 3-toothed ray flowers, opposite leaves, and hairy stems.
Cotyledons club-shaped with slightly indented tip. Hypocotyl is very short, green, becoming maroon with age. Young leaves opposite, triangular with slightly toothed margins, and covered with hairs.
Club-shaped with slightly indented tip.
Erect, reaching up to 60 cm (23.62 inch) height, freely- branched, green or less often maroon-tinted, and covered with hairs.
Opposite, oval to triangular, coarsely-toothed, petiolated, and densely covered with hairs on the upper surface. Lower leaf surfaces have hairs that primarily occur on the veins.
Many flowers are produced from terminal stems or from leaf axils. Flowers are less than 1 cm (0.39 inch) wide and consist of 4 to 5 white (or less often pink) 3-toothed ray flowers, many yellow disk flowers.
May - November.
Brown to black achene, 1.5 mm (0.059 inch) long, hairy, tapered from the base to the apex, with a white pappus that resembles a crown.
Germination occurs in late spring until autumn, fresh seeds are not dormant and can germinate until late autumn.
Viability of Seeds
More than 10 years.
Up to 7,500 seeds per plant.
Waste ground, cultivated areas, roadsides.
Warm and loamy or sandy loam soils.
Galinsoga ciliata is achallenging weed in vegetable and nursery crops and greatly reduces yield due to strong competition for water and nutrients and high abundance.
Useful non-chemical contribution to Integrated Weed Management
Mechanical control methods are very effective in seedling stage.
