Thiessen is an early saskatoon with large, juicy fruit about ⅔ inch across. The berries ripen over an extended period, giving repeated fresh pickings. It suckers less than Northline.
Its early flowering can expose the blossoms to spring frost, an important distinction from later flowering selections.
