This plant species possesses several uses and qualities that make it appealing for various purposes:

1. Ornamental Plant: Piptanthus nepalensis is prized as an ornamental plant for its beautiful golden-yellow, pendulous flowers that appear in late spring or early summer.

Its aesthetic appeal makes it an attractive choice for gardens, parks, and landscapes.
2. Wildlife Attraction: The bright and showy flowers of Piptanthus nepalensis attract pollinators like bees and butterflies, contributing to biodiversity and ecosystem health. The plant's nectar and pollen provide essential food sources for these beneficial insects.

For instance, some communities in the Himalayan region use the bark and leaves in herbal remedies for certain ailments, though it's essential to exercise caution and consult qualified healthcare professionals before using plants for medicinal purposes.
5. Nitrogen Fixation: Like other leguminous plants, Piptanthus nepalensis has the ability to fix nitrogen from the atmosphere into the soil through its root nodules. This nitrogen-fixing capability enhances soil fertility, benefiting neighbouring plants.
