Vinca, commonly known as the "Day's Spring," is a flowering plant that blooms daily throughout the seasons. Belonging to the Apocynaceae family, it is an evergreen, upright subshrub with a height ranging from 30 to 60 cm. Its leaves are opposite, elongated and oval-shaped, with a dark green color and a subtle lighter tone. The flowers grow in the leaf axils, featuring a salverform corolla with five lobes arranged in a ring. They measure about 3 to 4 cm in diameter and come in shades of white, pink, or purplish red. One unique characteristic of Vinca is that, at the tip of its tender shoots, two flowers emerge between each pair of leaves as they grow. This unusual blooming pattern results in a long and continuous flowering period, making the plant appear lush and vibrant throughout the year. From spring to autumn, it never stops flowering, which has earned it the reputation of being the "Sun, Spring, and Eternal Bloom." Native to the West Indies, Vinca was introduced to China as early as the Song Dynasty. It thrives in warm and humid conditions and can tolerate partial shade. Propagation is typically done through sowing. Beyond its ornamental value, Vinca is also known for its medicinal properties. It contains over 55 types of alkaloids, including vinblastine and vincristine, which have shown significant effectiveness in treating various cancers such as choriocarcinoma, lymphosarcoma, and childhood acute leukemia. These compounds are among the most widely used anticancer agents worldwide, making Vinca not only a beautiful garden plant but also a crucial element in modern medicine. Its dual role as both an aesthetic and therapeutic plant makes it a remarkable species worth appreciating and studying further.
