I was wondering, “Does the word boysenberry come from the French word Bois for forest?”

Perplexity said, “The term boysenberry originates from its creator, Rudolf Boysen, a Swedish immigrant and horticulturist who developed the hybrid berry in California during the early 20th century. The name combines Boysen (his surname) with berry.”

The hybrid berry includes raspberries, blackberries, Loganberries and dewberries.
