They are biennial plant that grows at copse and grassland meadow in the sunny countryside fields (biennial plant sprouts in autumn, overwinter, and bear flowers in next spring). The bud shape reminds us of the writing brush, which is the reason they are named Gentiana zollingeri. When it’s clear and sunny, they’re open. Meanwhile, when cloudy or rainy, keep close. The flower is a horn shape about 2 to 2.5 cm long and several of them gather to bloom at the top of stalk. The flower is divided into 5 at the top, and there are also accessory paraflocculus between the divided flowers. This makes them seen 10 divided flower petals. The flower is blue-purple, and rarely white. The leaves thickly growing on the stalk are small egg-shaped, a bit thick, 0.5 to 1.2 cm long, and are often tinged with purplish red color.
