For example, different flowering morphologies could be artificially selected for in varying directions in order to better fit in different environmental conditions and with different populations of other plants. This variety could have significant implications on its role in an actual perennial polyculture. : 341 Indigofera flowers have open carpels, their organ primordial is often formed at deeper layers than other eudicots. Small flowers grow in the leaf axils from long peduncles or spikes, their petals come in hues of red or purple, but there are a few greenish-white and yellow-flowered species. Most of them have pinnate leaves made of three foliolates with short petioles. The branches are covered with silky hairs. Species of Indigofera are mostly shrubs, though some are small trees or herbaceous perennials or annuals. The unique characteristics it has displayed include potential for mixed smallholder systems with at least one other species and a resilience that allows for constant nitrogen uptake despite varying conditions. Some examples of this diversity include differences in pericarp thickness, fruit type, and flowering morphology. Specifically, there is diverse variation among species with a number of unique characteristics. Indigofera is a varied genus that has shown unique characteristics making it an interesting candidate as a potential perennial crop. They are widely distributed throughout the tropical and subtropical regions of the world. Indigofera is a large genus of over 750 species of flowering plants belonging to the pea family Fabaceae.
