Small Balsam (Impatiens parviflora) is an annual herbaceous plant species native to the United Kingdom, belonging to the Balsaminaceae family. It is commonly found in various habitats, including woodlands, hedgerows, riverbanks, and damp, shaded areas throughout the UK.

Small Balsam thrives in nutrient-rich, moist soils, often favouring shaded habitats with high levels of moisture. It can tolerate a wide range of soil types and environmental conditions, making it a common sight in both natural and human-altered landscapes.

Predators of Small Balsam include herbivores such as insects and grazing mammals, which may feed on its foliage. However, its ability to produce large quantities of seeds and rapid growth often allow it to outcompete native vegetation, leading to concerns about its invasive potential.

As an annual plant, Small Balsam completes its lifecycle within one year, germinating from seeds in spring, flowering in summer, and producing seeds before dying back in autumn. It reproduces primarily via seeds, which are dispersed explosively when the ripe seed pods are touched, aiding its spread to new areas.

Culturally, Small Balsam does not hold significant symbolic or traditional references in the UK. However, it is considered an invasive species in many regions and is subject to control measures to prevent its spread and ecological impact.

An interesting fact about Small Balsam is its rapid growth and ability to form dense stands, which can smother native vegetation and reduce biodiversity in affected areas. Additionally, its distinctive explosive seed dispersal mechanism has earned it the nickname “Touch-me-not.”
