The Eastern Redbud is one of the first trees in the spring to burst into a pink cotton ball of blossoms. The flowers come straight out of the branches and even the trunk and pop out before the leaves do. This is a beautiful and popular accent tree in Denver. The Eastern Redbud tree is surprisingly hardy, has a yellow fall color and does well in protected spaces. This tree is an understory species and thus, much like the Quaking Aspen, is somewhat shade tolerant.
This tree is native to the Americas spanning from Michigan to Texas, and requires very little maintenance. It grows 1 to 2 feet per year until it peaks out at he redbud grows to 25 feet with roughly a 20-foot spread. When the leaves drop in the fall, the bean-like seed pods that have formed on the tree branches throughout the summer remain.
The Eastern Redbud adapts easily to most soils, is disease resistant, and thrives in the Colorado Front Range. Ideally planted in full sun, or a spot with partial shade.
A gorgeous spring flowering crabapple, ‘Adams’ is a great Colorado tree and perfect for small yards or spaces due to its smaller stature than other crabapples. Adams Crabapple is a strong tree with good disease resistance. The foliage has a reddish tint in spring, is green all summer, and turns golden yellow in late autumn. It produces 5/8” bright, glossy red fruit that persists all winter. This crabapple grows to 20′ and does best in full sun and moist, well drained, slightly acidic soil.

The American Hornbeam is a slow growing, deciduous, small-to-medium sized understory tree with an attractive round form. Being a native forest understory tree, it is useful for shady landscapes and naturalized or woodland gardens. It is native to the midwest where it is typically found in rich moist woods, valleys, ravine bottoms, and rocky slopes along streams. That said, this tree thrives where many others do not—in 'partly shade' and 'mostly shade' areas in your landscape. It should be noted that this tree can be planted in full sun as well, but due to the very hot Denver sun (as compared to the midwest) it may do best with some shade. This tree is highly adaptable which is why ArborAdvisor recommends this tree for areas with questionable or varying sunlight.
This tree typically grows to be 20 feet tall by 20 feet wide. The trunk is a unique smooth grey color and larger branches of a mature tree exhibit a distinctive muscle-like fluting that has given rise to another common name of "musclewood" for this tree. Flowers appear in spring in separate male and female catkins, with the female catkins giving way to distinctive clusters of winged nutlets. New leaves emerge reddish-purple in the spring, changing to dark green, then turn yellow to orange in the fall.
The extremely hard wood of the Hornbeam was once used by early Americans to make bowls, tool handles, and ox yokes. Commercial use of the hornbeam is not practicable, however, due to the limited amount of wood that can be harvested per tree.

The American Linden starts out pyramidal in shape but becomes rounded at maturity. Its benefits go far beyond its ornamental features. The wood is valued for its light but strong nature and is suitable for a wide variety of uses. Parts of the tree have medicinal uses, and some consider the honey from Linden flowers to be some of the best available. Be careful when applying street or sidewalk ice melt/salt as Linden trees don’t do well with salts.
The American Linden tree is an excellent choice for almost any yard or landscape–simply plant it in full sun and enjoy it for years.
