Goa: After eight years, Nirankal hills are alive with the colour of karvi

On the deep green hillsides of the Western Ghat forests at Nirankal, Ponda, specs of purple have begun to appear. This phenomenon is seen once every eight years — the blooming of the karvi flower, known botanically as strobilanthes callosa. In a week or two, the pink and white buds will be replaced by thick patches of purple, once the karvi is in full bloom.
