Spotted jewelweed (or orange jewelweed), Impatiens capensis, has orange flowers, and pale jewelweed (or yellow jewelweed), Impatiens pallida, has yellow flowers (rarely cream-colored flowers).
These are plants of moist, rich soils in valleys and stream-bottoms. The pale jewelweed tends to grow slightly taller and to tolerate somewhat shadier sites than the orange jewelweed, while the orange jewelweed is more common and more able to grow in disturbed areas.
Both have been used as preventatives and palliatives for poison ivy rash.
