As autumn sets in, the southern Chinese city of Nanning is welcoming a vibrant display of blooming flowers. Recently, a spectacular sea of Ruellia simplex has come into bloom across the lush lawns of the Yong River.

Widely regarded as the mother river of Nanning, the Yong River's banks were once largely untamed, characterized by rugged wasteland and mudflats. Years of comprehensive rehabilitation and careful cultivation have transformed the area into a beautiful waterfront corridor. Now, the expansive purple blooms stretching over ten acres stand as a signature autumn attraction along the river.

The Ruellia simplex flower lasts only a single day, unfurling at dawn and fading by dusk, with new blossoms eagerly taking their place the following morning—a cycle that has earned it the local name “Day-to-Day New.” The delicate purple petals dance in the breeze, drawing countless residents and visitors, all eager to capture the beauty and immerse themselves in the picturesque riverside scenery.
