The plant is native to southwestern Australia, where it grows in a variety of habitats, including forests, scrub, and coastal areas.
Because of its decorative flowers, the plant is grown in many parts of the world, including North America and Europe.

The black kennedia is especially appreciated as an ornamental plant because of its unique and striking flowers.
The plant is sometimes used for erosion control due to its extensive root system and dense growth.

The plant thrives best in a Mediterranean to subtropical climate. It is fairly drought tolerant and can tolerate light frost.
Kennedia nigricans prefers well-drained, sandy, or rocky soil, but can also grow in poorer soil types.
Full sun to partial shade is ideal for optimal growth and flowering.

Young plants need regular watering, but once established, they are fairly drought-tolerant. It is important to keep the soil moist but not soggy.
During the growing season, the plant can benefit from a balanced fertilizer to promote healthy growth and abundant blooming.
Pruning is usually not necessary except to keep the plant in shape and remove dead or damaged parts.

The flowers of Kennedia nigricans are pollinated by birds, particularly honeyeaters, which are attracted to the striking colors and nectar.
The plant produces pods that burst open when ripe and spread the seeds. The seeds have a hard seed coat and can remain in the soil for a long time before germinating.
