A tree that never stands above the ground: Explore the underground species that flower, store water, and survive fires invisibly

Most people imagine trees stretching skywards, with towering trunks and leafy canopies reaching into the light. But in some of the world’s harshest landscapes, a far stranger form of growth has evolved: entire trees that live almost completely underground. These remarkable species hide their trunks, branches, and sometimes even their flowers beneath the soil, revealing only a small crown or a few blooms above the surface. This unusual strategy helps them survive wildfires, scorching heat, and extreme drought, making underground growth one of nature’s most ingenious survival adaptations. From the red sands of South Africa to the deep Kalahari and the lush forests of Borneo, scientists are uncovering a hidden world of subterranean trees, each one reshaping what we thought we knew about how
