Asteraceae (Composite Sunflower) Family
Plant is an upright, hairy annual or short-lived perennial. Preferred habitat is roadsides, fields, woods and the margin of fresh marshes. Distribution is throughout the Escambia region.
Leaves are alternate on the stem, often opposite at the stem base; consists of one whole part; pinnately (an elongated axis with branches, leaflets, or veins arising along both sides of the leaf stalk) to bi-pinnately dissected into filiform segments.
Flowers are in a panicle of heads; symmetrical in form; bisexual in nature. Flower color is yellowish-white to purplish-white. Flowers occur in the autumn.
Fruit is achene (a seed which outer layer is fused to it).
Though harmless, the plant is often mistaken for ragweed. Dog Fennel is pollinated by insects while all ragweed is airborne.
