This annual grows on a branching erect stem with many pointed leaves. At the top of each stem branch is one or more flowers, each one half to two centimeters wide. The tubular flower has two long, narrow, pointed upper lobes which are generally rich purple. The lower lip is fused into one three-lobed surface, which is purple with a large blotch of white in the center. The lobes may be quite pointed. There is sometimes some yellow coloration near the mouth of the tube.
