Now that we are officially “in” Spring, here are some facts about California Poppies. It became the official state flower of California on March 2, 1903. And, on April 6th it is California Poppy Day. Poppies are bright, cheerful, and easy to grow in your garden too. Like all plants, wildlife, and resources in our parklands–they are protected by law. Keep them in the ground where they belong.
