Flowering trees are a type of tree that produce flowers, often in the spring or summer. Two examples of flowering trees are lindens and catalpas. Lindens are deciduous trees that are native to Europe and North America and have heart-shaped leaves. They produce fragrant yellowish-white flowers in the summer. Catalpas are also deciduous trees that are native to North America and have large, heart-shaped leaves. They produce white, bell-shaped flowers in the spring.
