Ohanabatake: Norikura’s Alpine Flower Garden
Ohanabatake, meaning “field of flowers,” is Mt. Norikura’s alpine flower paradise. Just a few minutes’ walk from the Norikura Bus Terminal, this natural garden is nestled in a hollow between two peaks. Its level terrain and wooden boardwalk give easy access to visitors of all ages and ability levels. Many flower varieties are in bloom during Mt. Norikura’s short summer, from mid-July to mid-August.
One of Ohanabatake’s most prominent species is the deciduous shrub known as Aleutian avens (chinguruma), whose flowers have creamy white petals and a bright yellow center. Like many alpine plants, it is small and appears delicate, but is actually hardy enough to withstand the severe winds, deep snows, and intense sunlight of an environment 2,680 meters above sea level. In autumn, Aleutian avens is transformed: its green leaves turn red, and the developing seeds sprout pink-and-white, frond-like filaments reminiscent of waving sea grasses.
The narcissus anemone (hakusanichige), another yellow-and-white flower, grows in clusters reaching 30 to 60 centimeters high. The white “petals” of its blooms are actually sepals—the leaf-like structures at the base of flowers where the stem attaches. The sepals of most flower species are green, not white, but those of the narcissus anemone have evolved to mimic white petals. There is also a rare form of the plant with sepals that retain patches of greenish-yellow. Narcissus anemone is a favorite of bees and butterflies.
The Kamchatka lily (kuroyuri) is easy to spot. Its tall stems are topped by blackish-purple flowers, sometimes dappled with yellow. In English, the species is known by many different names, not all of them flattering. In addition to “chocolate lily” and “wild rice,” it may also be called “outhouse lily,” “skunk lily,” and “dirty diaper.” These nicknames come from its smell, which varies in strength but is generally unpleasant. Even so, the odor serves a useful purpose—it attracts flies, which are the flower’s main means of pollination.
A full circuit of the boardwalk takes 30 to 40 minutes, but visitors may wish to spend longer examining and photographing the more than 30 alpine species at close range.
