What is the world's largest type of flowering plant by height?

The world's largest type of flowering plant by height is the Eucalyptus regnans tree, also known as the mountain ash. It is native to southeastern Australia and Tasmania, and can grow up to 330 feet (100 meters) tall, making it one of the tallest trees in the world. These trees have a straight trunk, with a rough bark that sheds in strips, and produces clusters of white flowers from November to February.

Due to their rapid growth, eucalyptus trees have been planted throughout the world, but they are not always considered beneficial to the environment. In some regions, they are considered an invasive species because they consume large quantities of water and nutrients, and release chemicals that can inhibit the growth of other plants.

Overall, the Eucalyptus regnans is an impressive specimen of the natural world, with a distinctive appearance and diverse ecological impact.
