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.

This tree is very popular due to its attractive mottled bark, fast growth rate, adaptability to many planting environments and soils. Its leaves turn yellow in the fall but it is not known for its brilliant fall color.
Its handsome mottled bark and large leaves make it an asset in any location where there is room for it to grow and display its best features. This tree will grow to 80-100 feet tall in time with a 30-50 foot spread, so plant your American Sycamore in the right spot with plenty of room.

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.

Prunus avium ‘Bing’
The Bing Cherry is one of the best and most famous cherry tree varieties. This is ArborAdvisor's SWEET cherry tree recommendation for Colorado. The Montmorency Cherry tree is the SOUR variety recommendation. The main difference between the two is the Montmorency is self-pollinating so you can plant just one to get fruit, the Bing however, requires a pollinator tree nearby to help it produce fruit. (Yes, both cherries taste great in pies.)
The Bing Cherry is a beautiful small fruit tree with spring flowers and delicious sweet cherries. In early spring, this tree is covered in beautiful white flowers. Later in the spring and through the summer bright green leaves persist with deep garnet, almost-black looking fruit. At maturity this tree will reach 16-20 feet but can be held to any height with pruning. The cherries are very large, dark, delicious—great for baking and preserves. It's cherries will be ready to harvest in mid to late June.
Note: The Bing Cherry does require cross-pollination, so another variety cherry tree nearby is necessary if you want it to produce fruit. Although almost any other sweet cherry will cross-pollinate with a Bing, we recommend the Black Tartarian Cherry tree which does well in Colorado and is a great pollinator tree. You may consider looking at existing trees within 100 feet of your property to see if a pollinator tree already exists.
As with all cherry trees, the Bing has a beautiful round shape for a featured spot in the landscape. It is extremely winter hardy and very adaptable. Fruiting time can take a couple years depending on soil and weather.
Hardy to -30° Maximum elevation: 6,000 ft
Black Tartarian Cherry
Prunus Avium 'Black Tartarian'
The Black Tartarian Cherry is a beautiful tree that provides excellent fruit. ArborAdvisor recommends that this tree be planted within 100 yards of the Bing Cherry (a recommended sweet cherry tree) for pollination purposes. The Black Tartarian acts as a great pollinator for many cherry tree varieties and is a beautiful tree that provides years of delicious fruit. This cherry tree is the quickest to produce fruit after planting—about one year later.
The Black Tartarian will have an abundance of white, fragrant flowers in the spring which attracts butterflies. As the summer arrives, this cherry tree will fill out with shiny green leaves and begin to form dark cherry fruit which will be ready to pick around June. The Black Tartarian is about 1-inch in size with a deeply purple hue. The stone comes loose easily from the cherry, so even if you’re pitting the cherries, you won’t have to work very hard.
This tree is hardy, disease resistant, and tolerant of most soil conditions. It is bigger than the other (semi-dwarf) cherry trees in our catalog, growing to around 25-30 feet tall. This tree can be trimmed back to be smaller as needed.

Malus sylvestris 'Honeycrisp'
The Honeycrisp Apple is consistently one of the best-selling apples trees on the market and one of the best fruit trees for cold weather. One of the benefits of this tree is that the delicious round yellow fruit that ripen in September don’t immediately drop, so you can take your time picking them. Plus, the apples keep until roughly April in storage and retain their crispness. This apple can be used for cooking and baking.
Note: This tree requires another type of apple tree within 500 feet to act as a pollinator. You may want to look around your neighborhood to see if another apple tree exists already.
This tree only grows to 20 feet and spreads an equal distance so it is the perfect size for an urban or suburban garden. Its low canopy makes it ideal for planting under power lines or in other such troublesome locations as well as convenient in picking apples without needing an extension ladder. It needs full sun for optimal growth and you can increase your fall yield if you plant another variety of apple tree close by to aid in pollination.
