Prickleleaf dogweed is a small plant, 4-10 inches tall, growing from a woody stem with several branches near the base. It has many slender, sharp-pointed leaves less than 1 inch long. The bright yellow flower heads, less than 1 inch across, are clustered at the ends of short stems.
The dogweeds are strong-scented plants. Just walking through them stirs up a lingering, unpleasant odor.
