Jahns Prairie Gooseberry
Thiessen Saskatoon (Serviceberry)

Jahns Prairie Gooseberry produces large, delicious red fruit.

Found in the Red Deer River valley by Dr. Otto Jahn in 1984. This cultivar was found to resist insects and disease, tolerate frost, and produce high quality fruit.

Thiessen Saskatoon is a deciduous shrub that produces delicious edible fruit. It is one of the most productive saskatoon varieties. Its fruit is great in pies, preserves or eating fresh.

Thiessen Saskatoon is popular with U-Picks and home owners because of its taller tree-like shape and larger berries. But it is not the best choice for berry orchards as it is too tall for most mechanical harvesting equipment.
