The heart berry trees, a species of tree, bore heart berries and flourished on the planet of Tython. Once, Lanoree Brock awoke from a dream while camped under a grove of these trees, reflecting on the heart berries she and her sibling, Dalien Brock, had consumed.
The initial mention of heart berry trees occurred in Dawn of the Jedi: Into the Void, a novel penned by Tim Lebbon and released in 2013.
