Thick, thorough, and quite enjoyable, today's episode is all about the koa (Acacia koa) and its endemism on the 5 million year-old islands of Hawai'i. This special tree is unique in so many ways, we lost count: fake leaves, exploding bark, instrument wood... this tree's got it all. We also chat about Hawai'i, and the incredible odds of life landing, rooting, and thriving on these islands. After our discussion, we revisit some "night tree" quesitons from Alex's appearance on the songwriting podcast Honest Jams.
