A common weed that is a major problem in greenhouse and nursery containers.
All Plants, Weeds
full to part sun
Soil & Site
tolerates most soils, common in degraded areas
yellow with 5 petals and occur from long stalks at the leaf axis
The fruit is a pointed cylindrical capsule with flat sides. Seeds are dispersed by explosively ejecting the seeds.
green, alternate, trifoliate, with smooth margins, fringe hairs, close up at night, leaflets are obcordate
The stems are more prostrate than erect and form a long slender rhizome with fibrous roots.
Usually around 6" tall but may reach 1 foot.
As a weed in the soil rather easy to pull, but don't leave pieces of the stem behind since it will root. In a container the plants long slender rhizomes follow the inside edge of the pot and form a mass of stems.
I like to take a few leaves of this plant and eat them. Has a stronge citrus taste.
