Restoration on the colonies of black tulips

Memorial project of the 100th anniversary of Kuroyuri-kai

The Kuroyuri-kai of Hokkaido University was founded in 1908 by students with a love for the fine arts. The club was named after the black tulips, Fritillaria camschatcensis, once found in abundance throughout the campus but virtually extict in recent years. Thanks to the efforts of students and alumni who secured and planted bulbs in 2005 as part of the club's centennial activities, their blooms may be enjoyred again each May.
