Botanic information
Leaf: There is only a single channelled light green linear leaf that clasps the stem and may have a purplish tinge.
Flower: The labiate flowers open during mid-day and are lilac blue with the upper 3-segments spotted in dark blue. All 6-petals and sepals are a similar shape and do not form a lip. The flowers are arranged in an upright raceme that appears during spring.
Fruit: The small capsule is not commonly seen and the plant is normally reproduced vegetatively.
