Description
This annual herb grows tall. It has few or many tufted branches originating from the base of the plant. They are crowded together in small but distinct groups and some stems may have one or two branches near the base. The stems are glandular and are covered in small, down-like hairs. They may have a few reduced leaves low down on the stem. The radical leaves are oppositely arranged and cross each other. The bases are cone-shaped and each leaf tapers to a petiolar part that is at least half as long as the length of the blade.Flowers are borne in terminal racemes. The flowers can be quite dense at first, but they spread as they open. The densely hairy corolla tube ranges from white to a mauve-blue in colour and change colour on individual plants. There is some white or yellow around the mouth and in the throat. Each flower has four stamens that are just visible in the mouth. The flowers produce capsules as fruits. They contain violet-blue or pale seeds.
