Darkness at night is as important to plants and wildlife as sunshine in the day. Plants need periods of darkness for healthy flowering, pollination, fruit set, and dormancy. The wildlife associated with our native plants need darkness, too. In this presentation, we’ll look at what goes on in the dark, why your native landscaping needs darkness at night, and how light pollution affects flora, fauna, and humans. We will also discuss easy and cost-effective solutions to this growing problem.
