Indigofera hirsuta has been widely introduced as a cover crop and forage plant in the tropics, and is now naturalized in many parts of the world including the Americas. It may compete with and dominate the native flora, as it is well adapted to a wide range of soil types. As a free-seeding annual without specific Rhizobium requirements, it can quickly spread and naturalize in suitable habitats, especially arable and disturbed land. It has been declared a weed in many countries - in Florida, the species has proven to be self-regenerating, even in fields that have been burned or disked[

]. The seed has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[
