This week’s guest is Scott
Calhoun – a well-known lecturer, writer, editor and author of several books
including a few that take on gardening in dry climates like that of his home
state of Arizona. We talk about the conscientious use of water, and plants some
people call “the wood lilies:” Yucca, Agave, Nolina (bear grass), and the like. (RIGHT: Spiky Yucca
rostrata with dark pink allium and

species and varieties I might grow in my Zone 6 garden. Scott tells of Yucca
rostrata, a strappy leafed plant that
eventually develops a trunk like a palm tree. He’s seen them growing in Denver
on mounded, fast-draining soil. Drainage is the key to growing most of these
plants – especially the cold-hardy cacti we also talk about. All cacti
originated in our hemisphere, and there are even some super-hardy species that
are indigenous to Canada.
Below is a list of hardy “wood lilies.” For more information, visit Scott’s website.
