Kiku: The Art of Chrysanthemums Opens at NYBG

The New York Botanical Garden is celebrating chrysanthemums — the most iconic of all Japanese Fall-flowering plants – in an elaborate new Kiku exhibition running from October 8-30 in the Enid A. Haupt Conservatory.

As the latest in a compendium of beautiful programming for the garden’s most underrated season, the annual display of Kiku– which means ‘chrysanthemum’ in Japanese– is sure to enchant. Kiku is the national flower of Japan, part of the Imperial Crest, and the subject of regular exhibitions at the Shinjuku Gyoen National Garden in Tokyo, where over the years Japanese masters have trained New York Botanical Garden Staff to cultivate special shapes and colors in the traditional Imperial style.

Kiku Modern

What is so amazing about this year’s kiku exhibit is the preparation and meticulous technical skills employed behind the scenes to create both traditional and new experimental flower forms.

It takes the staff up to 11 months to grow and sculpt the various forms to be displayed. The kiku design team includes the Foreman of Gardeners, James Harkins, who trained with and works alongside kiku expert Yukie Kurashina, who was educated by kiku masters in Tokyo starting in 2004.

Francisca P. Coelho, the Vivian and Edward Merrin Vice President for Glasshouses and Exhibitions, who designed the display, likes to call it “kiku modern” for its “contemporary take” on traditional Japanese designs; for example, Coelho has incorporated stunning sweeps of native grasses like the pinkish-lavender Muhly Grass (Muhlenbergia capillaris) and South African Bristle-leaved Red Top (Melinis nerviglumis).

Living Sculptures

One of the most beautiful plant forms showcased in the exhibit is called Ozukuri (thousand bloom)– a dome-shaped array of 200 symmetrically-placed chrysanthemum blooms grown from a single plant stem. The process is incredibly intricate: as the plant grows from its single stem, branch tips and side branches are pinched off until only five strong branches remain.

The plant is then re-potted in a special large wooden container (called a sekidai). Each of the branches is tied to a vertical stake to help it grow straight, and when the branches reach 6 feet high, they are untied and re-tied to an even larger frame. In the end, hundreds of simultaneous blossoms are shaped into a massive display; and just in case a bloom is damaged or a stem breaks, back-ups are cleverly tucked away beneath the branches.

Besides the impressive Ozukuri form, the exhibit features a dramatic cascading form called Kengai, meaning “overhanging cliff.” These flowers have been trained to look like plants in the wild flowing down the side of a cliff– an awesome visual effect.

The plants are each grown from a single stem trained along a wire. As the branches grow, the chrysanthemums are pinched off so that many short branches develop. Eventually, when it is large enough, each plant is moved to a larger pot and tied to a boat-shaped, horizontal frame of wire mesh. Branches are precisely woven through the mesh and tied in place so that the frame will become covered with hundreds of small flowers. When the buds start to open, the frame is tilted down like a cascade.

Starting in July, hundreds of plants in the greenhouses are covered and ‘put to bed’ from 3 in the afternoon to 8 in the morning. In this way they will be tricked into blooming in early October, just in time for the exhibition.

Two additional forms– Shino-tsukuri (Driving Rain) and Ogiku (Double and Triple Stem)– are also carefully cultivated for the exhibition. For Ogiku, which are luscious, large blooms perched at the end of tall stems, only three flower colors are used– pink, yellow, and white. The stems are in pots buried in soil and placed in a diagonal braided design that is supposed to mimic the bridle of the emperor’s horse.

Butterflies, Bridges, and A Blooming Wall

New this year are colorful, butterfly-shaped kiku, created by using a technique similar to the cascading forms. Each wing of the butterfly is grown from a single stem and the branches are woven into a mesh armature that is tilted into its final “flying” position when the buds are ready to bloom. Other new contemporary forms include curve-shaped bridges and a blooming wall of flowers, both of which are constructed using techniques adapted from the cascading forms.

Carefully-Timed Blooms

In general, chrysanthemums need about 14 hours of darkness in order to form flower buds, and the darkness cannot be interrupted. Normally they would bloom in November, when the days are shorter, so getting the plants to bloom in October is a challenge.

The solution: Starting in July, hundreds of plants in the greenhouses are covered and ‘put to bed’ from 3 in the afternoon to 8 in the morning. In this way they will be tricked into blooming in early October, just in time for the exhibition. The blooms only last 10 days to two weeks. So, during a long exhibition period, a lot of substitute plants are kept in reserve.

Blazing Colors of Japanese Maples

Prominently placed throughout the exhibition are gorgeous varieties of Japanese maple trees– a perfect complement to the flowers. Outside on the grounds, the Japanese tradition of momijigari –– literally “maple hunting”– can be experienced at the newly expanded Judy and Michael Steinhardt Maple Collection. The collection, which covers about five acres amidst huge rock outcroppings, now boasts new Japanese maple species and cultivars specially selected for their adaptability to the New York climate and suitability for home gardens. For their brilliant colors and lovely feathery leaves, these autumn trees are a spectacular treat.
