Painted Leaf

Habitat:

part shade, shade, sun; moist, gravelly soil; disturbed areas, roadsides, open woods, floodplains

Notes:

'tis the season, I guess. A large patch of this native wild poinsettia was growing at the park. Growing together there were individuals with very different leaves (seemingly a different species all together), however it seems the leaf shapes are very variable within the species. Compare the 1st and last photo.
