Texas Red Oak
The Texas Red Oak, also commonly referred to as Spanish Oak, Nuttall's Oak, Spotted Oak, Rock Oak, and Buckley Oak, is a large deciduous tree native to Oklahoma and Texas. The Texas Red Oak is the red oak tree recommendation by ArborAdvisor for Colorado. (It is almost indistinguishable from the Schumard Oak.)
This is a stately tree with a wide rounded crown which provides great summer shade. Like all oak trees it produces oval acorns (to 1 1/2" long) with scaly cups that mature in two seasons after planting. (The acorns are loved by small mammals.) This tree has dark green leaves that are 4-8'' long. Its fall leaves range in color from yellow-gold to bright red depending on seasonal and soil conditions. This tree's colors change later in the season, so while other trees are already turning brown, this tree will still be brightly colored.
The Texas Red Oak is very popular due to its fast growth rate, ease of care, fall color, and ability to thrive in varying soils including semi-wet areas. This tree is popular with city foresters along the Colorado Front Range. It does well in winter conditions and makes a perfect shade tree, street tree, or ornamental tree. This tree usually reaches a height of around 35-50 feet and a canopy width around 30-35 feet at maturity.

Fagus sylvatica 'Roseomarginata'
The Tricolor Beech is a great shade tree with unusual foliage which thrives best in partially sunny and mostly sunny areas. Its early spring leaves are marbled with silvery-white and cream, changing to purple leaves edged in pink and white in the summer. Up close its leaves are purple with a border of blushing white and rose. This tree blazes with color for a stunning effect— it really stands out with its unique color. The Tricolor Beach becomes a large tree at around 30 feet tall at maturity, so it needs adequate room to grow. It can be a versatile tree but it's mostly ideal for lawns—possibly as a front yard statement tree or possibly as a backyard shade tree in a city environment.
This is a slow-growing tree so it can be used in landscapes, but be thoughtful when planting as it will become a large tree. Requires regular watering especially during the summer months. This is a cold-hardy tree ready to stand up to Colorado winters. It should be planted in well drained areas.
