Habit Indigofera tinctoria grows as a perennial shrub up to 2 m in height. New vegetation is pubescent. The odd pinnately compound leaves are arranged alternately with small linear stipules at the petiole base. The 9-15 leaflets are oval to obovate with a mucronate leaf apex and an entire margin. The abaxial leaf surface is minutely pubescent.
The complete, perfect, zygomorphic flowers are arranged in terminal or axillary racemes. The calyx 5 are partially fused, pubescent green sepals forming a tube with the sepal lobes the same length as the tube. The corolla has 5, pink to salmon, petals, the upper enlarged to form the banner and the lower 2 fused to form the keel. There are 10 diadelphous stamens. The ovary is superior and has a single locule with numerous seeds. The fruit is a straight, round, pubescent when immature becoming glabrous with age, brown legume up to 4 cm (usually less) in length at maturity that splits along 1 suture line.
Indigofera tinctoria differs from I. suffruticosa primarily on the shape and length of the fruits.
