  • John Little on Caring for Gardens and Gardeners (#48)
    Dec 7 2025

    Learn more about botanicbootcamp.com.

    JOHN LITTLE BIO

    John Little has been reimagining what urban nature can be since founding the Grass Roof Company in 1998. Over the past 25+ years, John has designed and built more than 400 small green-roof structures and various other species-rich planting with walls engineered for nesting, hibernation, and year-round habitat.

    His nonprofit Care Not Capital pushes for a fundamental shift to redirect funds from one-off capital projects toward ongoing, human-powered stewardship that benefits both biodiversity and communities.

    Here are the core ideas John argues for—putting the best gardeners in the poorest places, moving money from capital into care, understanding that gardened places are best for biodiversity and people, moving novel landscapes higher up the Biodiversity Net Gain (BNG) metric, understanding that a modern public space gardener is much more than a horticulturist, keeping waste on site and using it to make places beautiful and biodiverse, and putting soil and plants on roofs.

    You can connect with John on Instagram at @grassroofco and @carenotcapital.

  • Molly Hendry on the Bergamo Landscape Festival (#47)
    Nov 8 2025

    Discount link for Botanic Bootcamp.

    MOLLY HENDRY BIO

    Molly toggles the worlds of design and plants as both a trained horticulturist and landscape architect. She has stepped out to create her own garden design studio, Roots and Ramblings, where she does design work for folks in the Birmingham, Alabama area and beyond. With this studio, Molly is most interested in the intersection between people and places. She loves designing gardens for "hands in the dirt" gardeners, focusing on how design is not just a masterplan on a piece of paper, but an ongoing dialogue between a person and a place... often with a spade in hand!

    Up through July 2023, she was the Associate Director of Gardens Support for the Friends of Birmingham Botanical Gardens for 5 and a half years. There she was actively involved in the horticultural and design development of the 26 unique gardens that make up Birmingham Botanical Gardens. One of her top honors is that she spent 10 months living in the UK, sinking her hands into the soil at some of the top gardens across the country as the Garden Club of America's 2016–2017 Royal Horticultural Society's Interchange Fellow. You can learn more about Molly by visiting her website Roots and Ramblings and by following her on Instagram @mollshendry.
