Even with several years of studies abroad, the Norwegian landscape remained an important motif in Sohlberg's production. He visited and stayed places where his contemporary artist colleagues did not necessarily go. This way, it can be said that he contributed to giving more unknown places in Norway a cultural and artistic identity, through his paintings.

Sohlberg's depictions are drawn between the traditional landscape motif and the abstract form. In any case, his strength lies in the presentation of nature, showing a metaphysical universe where thoughts, the sensual and the eternal merge in the motif, and is taken out of time and place.

Blomstrende kirsebærtre (Kalviken, Kjerringvik) (1907) shows a summer landscape from his stay in Kjerringvik between Larvik and Sandefjord. The area was a favorite subject for Sohlberg in the period 1907-1910, where he painted landscapes both summer and winter
