Description edit

This is an erect annual herb reaching about 35 centimeters in maximum height. It produces a thin stem and narrow leaves and looks grasslike before flowering. It produces a showy inflorescence which is separated into interrupted levels, with each level producing a row of one to several flowers. Each pea-like flower is just over a centimeter wide and bright purple with white upper lips. The fruit is a capsule containing four seeds. The plant is relatively small, but its features are larger than most other Collinsia, hence its common names.
