Flexi Says: The first vascular plants were just a few centimeters tall. As they evolved, they grew taller. All tree species are vascular plants. The tallest trees are redwoods (Sequoia sempervirens), which grow in California. Redwoods typically reach heights of 300 feet (91 meters). The tallest known redwood, a tree named Hyperion, was discovered in 2006 and is 379.7 feet (115.7 m) tall.
