A seed slips beyond a garden wall. A seaweed drifts through an ocean. A tree is planted on a shifting border. A shrub is uprooted from its culture and its land. What happens when these plants leave their original homes and put down roots elsewhere?

Born in Canada to a Taiwanese mother and a Welsh father, steeped in both literary and scientific traditions, Jessica J. Lee is a perfectly placed observer of our world in motion.

In this vibrant book of linked essays she explores the entanglements of the plant and human worlds, and the echoes and counterpoints she detects in the migration of plants and people - and the language we use to describe them.

Each of the plants considered in this collection are somehow perceived as being "out of place"- whether weeds, samples collected through imperial science, or crops introduced and transformed by our hand.

Combining memoir, history, and scientific research in precise and poetic prose, Jessica J. Lee meditates on the question of how both plants and people come to belong - or not - as they border cross, and reveals how all our futures are more entwined than we might imagine.
