Everything you want to know about native flowers!

It's time for our weekly expert feature where we select a subject and put your questions to the people who know it best. Today we're talking about flowers - specifically the native flowers of Aotearoa. We're lucky enough to have so many beautiful native species in New Zealand, in fact our guest today reckons there's approximately 2200 of them. It's Victoria University Emeritus Professor of Botany Philip Garnock-Jones, author of the Ockham Award-winning book "He Puawai: A Natural History of New Zealand Flowers". If you have questions for Philip send them through to 2101.
