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.

The American Yellowwood is a medium sized, low branching deciduous tree which features a broad, rounded crown and typically grows to around 30 feet tall in Colorado. This tree has 7-11 leaflets per stem which open in the spring as yellowish green, turn bright green in summer, and then turns beautiful yellow or orange in the fall. The Yellowwood has intensely fragrant white flowers appear in late spring and early summer, often in alternate years. These white, pea-like flowers form in 8 to 14 inch long clusters, followed by a flattened pod 2 to 4 inches long. This tree may or may not flower for the first handful of years, depending on the soil and conditions, but once the bloom begins it is a spectacular sight. Most often these trees are multi-trunked and have a smooth light gray bark. 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). The roots of the Yellowwood grow deep so other plants can be grown underneath where they will get filtered shade. This tree is very adaptable and can be planted in urban areas, used as a medium-sized shade tree near patios, or as a landscape tree.
This tree is a top choice among horticulturists and does very well in Colorado. ArborAdvisor gives you a tip-of-the-cap for originality to all of our clients who choose this tree.
