Easter Lilies, (Lilium longiflorum), with their large, white, trumpet-shaped flowers and wonderful fragrance are a traditional Easter time treat. Here are some tips for choosing lily plants that will last through the holiday season and beyond. Choose a plant with flowers and buds in various stages of development, preferably from tight bud to partially opened flower. Make sure the foliage is dense, extends all the way down the stem to the soil line and has a uniform rich, healthy, green color. All lilies are extremely toxic to cats and can cause kidney failure. Don’t bring lilies into a home with cats. Display your plant in bright, but indirect sunlight. Keep reading what to do with Easter lilies here.
