Chromolaena corymbosa, commonly known as Jack in the bush, is a perennial shrub native to tropical regions of South and Central America, including Brazil, Venezuela, and Colombia. It is typically found in disturbed areas, secondary forests, and along forest edges. This species can grow to a height of 1.5-2 meters and a width of 1-1.5 meters. Chromolaena corymbosa has a bushy form with small, white to pale purple flowers that bloom in clusters, known as corymbs, from which the species derives its name. The flowering season extends throughout the year in its native range, with flowers that are modest in showiness.

Jack in the bush is appreciated for its rapid growth and its ability to attract pollinators such as butterflies. It is used in tropical gardens for informal hedges or as a background plant in borders due to its dense foliage. In cultivation, it requires well-drained soil, moderate water, and thrives in full sun to part shade conditions. While not commonly available in the nursery trade, it can be propagated from cuttings or seeds. Gardeners should be aware that in some regions outside its native range, Chromolaena corymbosa can become invasive, so caution is advised when planting it.CC BY-SA 4.0
