This is the image I see when I start up the steps to our house. The Passion Flower vine grows every year and by September has completely taken over. The vine brings butterflies that lay eggs which turn into caterpillars which eat the leaves. The environment is perfectly balanced because the plant grows faster than the caterpillars eat. Also, I have Green Anoles that eat some of the caterpillars. No pesticides are needed. The blooms bring bees of all sizes that load up on the pollen.
