This image is in the public domain because the copyrights of the original work of art have expired. It is a reproduction of a painting by the Swedish botanist C. A. M. Lindman (1856–1928), taken from his book(s) Bilder ur Nordens Flora (first edition published 1901–1905, supplemented edition 1917–1926?).
The author died in 1928, so this work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 95 years or fewer.
