In this episode of The Sentimental Gardener, Cass chats with Jay Young, co-founder of Flinders Farmgate, a small-scale regenerative farm on Victoria's Mornington Peninsula. Alongside her husband Nick, Jay grows garlic, sunflowers, dahlias and seasonal flowers, while finding ways to share their special patch of land with the local community. We talk about how a friend's suggestion to grow garlic set their farming journey in motion, how losing an entire garlic crop led them to diversify into flowers, and how a sunflower picking event grew into something much bigger than they expected. Jay also shares what she's learnt about regenerative farming, building healthy soil, working with nature rather than constantly intervening, and the realities of balancing a growing farm business with family life. And, of course, we talk about her sentimental plants: the climbing beans that take Jay back to her grandparent's garden, the winter-scented flowers that remind her of an early job at a flower shop, and the sunflowers that continue to bring her joy.

Australian landscape architect and garden designer Timothy Mitchell joins Cass Dowding on The Sentimental Gardener podcast to talk about his early memories of plants, transforming tennis courts into a meadow of flowers and designing gardens en plein air. They also dive into finding beauty in Australian native plants, building a dry climate garden that actually works, letting a garden evolve naturally over seasons, and why the most alive gardens are always being edited, observed and mulled over.
Are you an Australian native plant fanatic? Well you're going to love this episode! Cass Dowding chats with Ben Clark, co-owner of Kuranga Native Nursery, about growing up surrounded by the bush in Warrandyte, followed by an early obsession with plants, to building a family business around Australian native plants. Ben shares how he first came to Kuranga as an apprentice, what happens behind the scenes in the nursery he now owns, and why the nursery has become such a loved destination for native plant buffs. They also talk about Kuranga's expansion to a second site at Warrandyte, running the business with his wife Alexa, raising kids around the nursery, and the joy of dispersing native plants into gardens across the state, and maybe Australia!
