Can we pollinate Catharanthus without bees or insects? If yes, then how to do it?
Due to the floral structure of the Rosy Periwinkle, they require insects such as butterflies and moths that have long tongues, and serve as better pollinators for this plant. The flowers of the Madagascar Periwinkle are often visited by a wide variety of insects including butterflies, moths, bees and even beetles. Furthermore, other studies have shown that the Madagascar Periwinkle is a very unique species within its family because of its self-compatibility meaning that they are able to pollinate themselves.
But how we can do it if we want to do it?
