Description [top]

Galinsogas (Asteraceae) are summer annuals with erect stems. Leaves are opposite, roundish to triangular in shape, 1 to 3 inches long and � to 2 inches wide. The small flower heads have 4 to 5 white ray flowers and yellow disc flowers. Stems and leaves are hairy in the most common species, G. quadriradiata (formerly G. ciliata), but G. parviflora stems and leaves are smooth or only sparsely hairy. In warmer climates, galinsoga is more common in spring and fall, less common in the summer. In cooler climates, germination can occur in spring, summer, or fall. [TOP]
