Black-Jack flowers are white with 5 petals. The center of the flower is bright yellow. The petals grow back from the center, creating a convex shape. The stamens of the flower protrude from the center of the flower. The 5-petal flowers of this plant make it a dicot Angiosperm. This flower can be found in eastern Canada and the south of the Unites States. They have bur-like fruits that stick to animals for dispersal. Because of this, they grow about 2 feet high, which allow them to attach to passing animals.
The flower had a bright yellow center covered in pollen with five white petals. The petals had ruffled edges and were wider near the ends. The whole flower was about an inch long and wide, and the center was about a centimeter long. The flower was light, so when the breeze blew by, the flower bent in the wind on its thin green stem. It would also bend easily when someone walked past it and brushed their leg against it.
