The American Sentry Linden is a large, fast-growing shade tree also referred to as an American Basswood Tree. It is a hardy shade tree, with a tall stately presence, providing great shade during hot summer months. This is a low maintenance tree–basically just plant it in a full sun location and watch it grow. (Just water occasionally in the first couple years during the hot summer months).
It grows to roughly 45 feet in height with a spread of 20 feet, substantial enough for a large landscape, but not too big or wide for a more smaller yard. It has heart shaped leaves that give a full effect to its spreading branches. The Linden is resistant to Japanese Beetles which are plaguing the Ash trees around Colorado.
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.

Even though this tree is native to North America it is uncommon which makes it even more unique when you see it in a landscape.
The Yellowwood is a moderate to slow growing tree which has a rounded bloom at maturity. Once established this tree is drought tolerant and would be considered a low maintenance tree. Basically just occasional watering in the middle of summer months and pruning as needed for shape (prune this tree in the summer).

A medium sized, upright deciduous tree native to Colorado. Small, heart-shaped leaves are a waxy-green in summer and brilliant shades of yellow to gold in the fall. A fast growing tree with smooth, white bark that becomes furrowed with age. This tree can be purchased in single stem or multi-stem "clump" form. Aspens can be planted in full or partly sunny areas. A very adaptable tree for a wide range of soil conditions.
It should be noted that Aspen trees don't always do well in the Front Range and have been know to have roots that spring up small sucker trees around the area below. Aspens are naturally a “succession” tree, moving into areas where other trees and shrubs were removed by logging, fire, erosion, insects or disease. As a succession species, they are not long lived and can be prone to disease and insect damage. It is smart to plant a few of these together as they seem to do best planted in groves. We did not remove them from the ArborAdvisor list however because of their iconic Colorado status, shimmering beauty, and the fact that they are perfect for certain types of planting locations—just not all.

Red Delicious Apple
Malus sylvestris 'Red Delicious'

Red Delicious apples are sweet, but very mild in flavor. The flesh is juicy with a light crispness. Blooms appear around mid April, with fruit ripening around mid September.
