From Cornell Plantations' description:
Gardeners are notorious for experimenting with improbable plants. The wonder of it is not that so many plants die in this process, but that so many live. How do plants not only survive, but even thrive, in garden conditions totally unlike the plants' wild habitats? Taking this question as her underlying theme, Hornig will present some of the less likely inhabitants of her garden, the South African species from the Eastern Cape region. She will compare their garden conditions with their wild habitats, offer some possible explanations for her success in growing these fantastic plants in upstate New York, and encourage all gardeners to be more adventurous.
