The kapok tree is a large tropical tree native to Central and South America, as well as parts of Africa and Southeast Asia. It can grow up to 200 feet tall and is known for its wide, buttressed trunk and large, spiky seed pods. The tree produces a lightweight fiber called kapok, which is often used as stuffing for pillows and mattresses. Kapok trees thrive in humid, tropical climates and are typically found in rainforests. They play a vital role in their ecosystem by providing habitat for various species, including birds and insects. The tree's flowers are also a food source for pollinators like bees.
