Our artificial outdoor plants and fake flowers are the most durable and weather-resistant. Improve the longevity of your silk outdoor arrangements with water-resistant UV treatment. These realistic outdoor plants and flowers make a lovely accent for your porch decor. We cannot guarantee the longevity of this product due to the varying levels of sun exposure in different states. We do always recommend adding a layer of protection with our UV Krylon Spray to help extend the life of the florals.
