Soldier - Galinsoga parviflora
Family: Asteraceae
THIS PAGE IS UNDER CONSTRUCTION.
Description
Galinsoga is an annual herb up to 2 m tall. The glabrous to pubescent stems are erect and often branched. The ovate to ovate-lanceolate leaves are opposite with short petioles. The leaf blades are sparsely hairy with three prominent nerves, shallowly toothed margins and wedge-shaped bases. The inflorescence is a small head composed of ray and disk flowers. The ray flowers are white usually five in number and lack a pappus. The disk flowers are yellow with a pappus of conspicuously fimbriate scales. The fruit is a four-angled achene flattened parallel to the involucral bracts.
Interesting facts
Galinsoga is a prolific seed producer. It is primarily a weed during the early growing season thriving under moist conditions. It is found in crop fields and waste places,
Galinsoga can readily germinate and make rapid growth early in the growing season allowing it to compete with crop plants. Because it grows best under moist conditions it can become a serious problem under irrigation or in areas that receive year-round rainfall.
