Origin:

Flowers occur in an elongating cluster at the ends of the stems, well above the rest of the plant. Flowers are bright yellow with purple-brown veining along the petals, and they are irregular in shape.

Characteristicts Important to Control:

Physical removal of individual plants can be very effective.
