Thiessen is one of the most popular Saskatoon or Juneberry varieties, with a particularly good sharp tangy flavour.
The tree is vigorous and the berry-like fruits are amongst the largest of their kind.
The fruits ripen progressively over a long period, starting in early summer.
Thiessen was discovered as a wild seedling in Sasketchewan, Canada, in 1906, making it one of the oldest and most widely-grown Saskatoon varieties. It is known to grow productively for more than 50 years.
