The Autumn Brillance Serviceberry is a medium-sized shrubby tree popular for its fall color and succulent summer berries (referred to as juneberries). This tree grows to be about 15-20 feet tall at maturity and is typically used as a shrub border in yards or grown as a small tree. In the spring, 5-petalled clusters of white flowers emerge which are followed by small green berries which gradually progress to red and then deep purple in the summer. In the fall, the 5 inch long leave turn into a spectacular reddish-orange in the fall.
This Serviceberry can be grown alone as a shrub or pruned to be a multi stemmed or single stemmed small tree. Many people in Colorado use this tree as a privacy screen as it has a wide spread and dense foliage. This is a very hardy shrubby tree which grows best in full sun and is tolerant of a wide range of soils. It has smooth light gray bark.
The juneberries which grow on this tree are commonly eaten raw or can be used in jams and pies.
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.

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.

This tree has fragrant smelling yellow clusters of yellow flowers that grace its branches in the spring. As summer progresses you’ll enjoy watching woody, pea-sized seeds form. Their light green shade provides a slight variation in color throughout your tree for the late summer. When autumn appears, your Linden’s leaves will take a dramatic step as green leaves transform to brilliant yellow.
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.
