“I want to explode the idea of beautiful ikebana,” says Kosen Ohtsubo, one of the foremost conceptual artists working in the Japanese tradition.

Since the 1970s, Ohtsubo has been unsettling the ancient art of flower arranging. Incorporating atypical botanicals like cabbage leaves or weaving in unconventional materials like bathtubs and scrap metal, the artist approaches making with the mindset of a jazz musician, a genre he frequently listens to while working. Improvisation and experimentation are at the core, along with an unquenchable desire for the unexpected.

An exhibition at Kunstverein München in Munich pairs Ohtsubo with Christian Kōun Alborz Oldham who, after discovering the ikebana icon’s work in a book in 2013, became his student. Titled Flower Planet—which references a sign that hangs outside Ohtsubo’s Tokorozawa home and studio—the show presents various sculptures and installations that invite viewers to consider fragility, decay, and the elusive qualities of beauty and control.

Given the ephemeral nature of the materials, photography plays an important role in most ikebana practices as it preserves an arrangement long after it has wilted. This exhibition, therefore, pairs images of earlier works with new commissions, including Ohtsubo’s standout orb titled “Linga München.” Nested in a bed of soil and leaves, the large-scale sculpture wraps willow with metal structures and positions a small candle within its center.

Similarly immersive is “Willow Rain,” which suspends thin branches from the ceiling. Subverting the way we typically encounter fields of growth, the work is one of many in the exhibition that seeds questions about our relationship to the natural world and the limits of human control.

Flower Planet is on view through April 21. Explore Ohstubo’s vast archive on Instagram.
