Visitor Center, Classroom 2, $45. Deserts are among the most inhospitable habitats on our planet, yet somehow they contain a vast amount of plant diversity. Kevin Tarner, succulent enthusiast and professional horticulturist, will begin with an overview of how cacti and succulents are able to thrive in the hottest places on Earth. Next, he’ll introduce the most desert-adapted and horticulturally popular plant families. We’ll then explore how to successfully cultivate and propagate desert plants. Each participant will get their hands dirty by creating their own succulent dish garden to take home.  Bring a container for planting.  Some light refreshments will be provided but you are welcome to bring your dinner with you.
