Morrison Polkinghorne is an Australian artist whose practice centres on monochrome ink works created from lotus petals collected in Cambodian temples. He lived for almost a decade in Cambodia where he lived and worked. There he developed a distinctive process of making ink from charred lotus petals offered at monasteries. The petals are transformed through a slow artisanal process using rainwater and earthenware vessels, often resting for a year or more before use.

Each artwork is created through repeated impressions of freshly cut lotus stems using this ink, forming layered tonal compositions in black and white. Numerology and counting are integral to his practice, with every lotus impression recorded and totalled. His works range from single impressions to large-scale paintings containing tens of thousands of marks, with his cumulative count now exceeding half a million lotus impressions.

Polkinghorne now lives and works in regional Australia, continuing his research into regenerative art practices, material processes, and the relationship between repetition, landscape, and stillness.
