Keralas Neelakurinji flower, scientifically known as Strobilanthes kunthiana, blooms only once every 12 years, transforming the hills into a stunning blue and purple landscape. The rare spectacle attracts nature lovers to destinations like Munnar, Eravikulam National Park- a UNESCO World Heritage Site, Rajamala, Koviloor and Top Station. According to Kerala Tourism, the best time to witness the bloom is between August and October. Visitors should check access restrictions, as some areas have been protected due to conservation concerns and elephant movement.
