The Nilkantha flower plant is a name often used in South Asian regions, especially in India and Nepal, and may refer to more than one species depending on local usage. However, in many areas, the "Nilkantha" flower is commonly associated with plants that bear blue or violet flowers, given that "Neel" means blue and "Kantha" can refer to throat or neck, often linked symbolically to Lord Shiva (who is called Neelkanth due to his blue throat).

Another candidate, in Himalayan regions, might be Rohdea japonica or certain native blue-flowered forest species. Below is the description based on the most commonly accepted plant:
