Creeping Indigo, often mistaken for common clover due to its simple leaf structure, is a herbaceous plant with sturdy stems and an extensive crawling taproot system. Recognizable by its small pink or pinkish-orange pea-shaped blooms, this invasive species poses a challenge with clusters of flowers measuring 4-5 mm in length, extending up to 10 cm. Another distinctive feature is its slender cylindrical seed pods spanning 15–25 mm.
Creeping Indigo employs several strategies for dissemination. Seed dispersal commonly occurs through mowers and contaminated soil, while water and mud attached to animals and vehicles serve as additional carriers. Flourishing predominantly in subtropical climates of south-eastern and coastal Queensland, this persistent weed has also found its way into the northern regions of the Northern Territory.
Though various herbicides show temporary effectiveness against Creeping Indigo, its deep taproot demands a gradual approach for lasting eradication. Swift treatment may trigger the weed to shut down, safeguarding its roots from the herbicide. While this approach may initially eliminate the flowers, expect a resurgence in a matter of weeks.
