Jac Semmler

Plant Practitioner — Australia

Rooted in the dry summer ecology of central Victoria, Jac Semmler’s love of plants and landscapes springs from a deep familial connection to the land. Descending from a lineage of gardeners, she has cultivated a responsive approach that intertwines ecological understanding, artistic vision, and technical expertise as a plant practitioner.

With a plant journey that is as diverse as their inhabited landscapes and a past environmental education and community engagement career in remote Australian locations, Jac’s professional plant path includes significant roles as a senior manager in ornamental plants, seeds, and plant trials, as well as Head of plants and strategy; each experience deepened the approach to plant life, cultivation, and landscape dynamics.

Jac Semmler has become renowned for groundbreaking work in dry summer planting design and a passionate advocate for plants as Director of Super Bloom, championing their adaptive potential and transformative power through planting design, art x plant projects and high-skill horticulture in Australia and Internationally. 

With a mission of ‘plants for the people’, Super Bloom’s work fosters enduring relationships between people and plants, challenging traditional approaches by positioning plants as active, intelligent collaborators in design through dynamic, resilient planting that delights through a year of wonder in dry summer climates.

Author of “Super Bloom” and “The Super Bloom Handbook”, Jac’s writing and practice champion a plant-led approach that heros the intrinsic beauty, complexity, and potential of plant life to be transformative.
