This is a tall bush along ravine stream bank in Parkwood Park of Decatur, GA. Note tall spikes of greenish-white flowers, straight or gently curved spikes. Leaves are opposite, with large leaves 5-lobed and smaller leaves 3-lobed or 2-lobed. Leaves feel rough and sandpapery. From the base of each pair of opposite leaves emerges another stem, which gives rise to more opposite leaf pairs, which gives rise to more stems with more leaves and flower-spikes, etc. Very fractal-like pattern. This bush stumped a Master Gardener with us.

    It is fall and the ambrosia is in full bloom.
    Giant ragweed (Ambrosia trifida)

    During the winter the stalks split or get cut off and Mother Nature pulls ice ribbons from the rooted remains.
