Moonflower is also called as moon vine. It is a species of night-blooming morning glory. It is native to Mexico and Florida. The flowers are fragrant, white or pink and large about 8-14 cm in diameter.
The flowers open quickly in the evening and last through the night, remaining open until touched by the morning sun. The Moonflowers bloom in spring and summer. The name moonflower derives from their blooming in the evening and their being round in shape like a full moon.
