Throughout a go to to the Zürich arboretum, Jonas Frei got here throughout a nut species hardly ever present in Europe. The Juglans cinerea, or white walnut, is native to the U.S. and Canada and has a ribbed, rectangular shell that after cracked, reveals a candy, fleshy innard. Its presence within the Swiss enclave dates again to 1887, when the botanist Carl Joseph Schröter planted a tree that finally produced the non-native fruits and sparked Frei’s enduring curiosity within the plant genus.
Based mostly in Schaffhausen, Frei is a naturalist, illustrator, and panorama architect whose curiosity in botany has taken him to gardens, arboretums, and parks all through Europe and North America. He lately hung out in Harvard’s Arnold Arboretum after being awarded the James R. Jewett Prize, which allowed him to expand his research on the walnut and discover the way it’s migrated over centuries. A lot of his work is concentrated on making science simply digestible and visually intriguing to a basic viewers. “Analysis itself actually is my purpose,” he tells Colossal. “I need to perceive the topic and make the data accessible by means of my writing and the aesthetical presentation of the range of species and cultivars.”
Shared by means of illustrations and flat-lay images, Frei’s research have lately culminated in a e-book dedicated to walnuts and hickories, which brings collectively the cultural, historic, and botanical significance of those numerous vegetation. “I used to be pushed not solely by my scientific curiosity in Juglandaceae but in addition by my enthusiasm for the aesthetics of their habits, leaves, and fruits. The readers of my e-book ought to be capable to make their very own journey of discovery by means of the walnut household, on the tracks I’ve uncovered with my analysis,” he says.
The expanded version of Frei’s e-book, which incorporates updates from his research at Arnold Arboretum, is out there together with posters, prints, and an analogous quantity centered on hazelnuts on his site. Observe his newest analysis on Instagram.
