Streets lined with greenery create a pleasant atmosphere and enhance the experience and livability of these often concrete-filled environments. Depending on the width of the street and the volume of traffic, there is more or less space available for trees. Underground infrastructure also determines the growing space available for trees. Additionally, factors such as wind, sun or shade, heat, and the degree of paving play a role in selecting tree species for streets.

Sun-drenched streets create very warm growing conditions for trees during the summer. If there is a lot of paved surface, little rainwater infiltrates the soil, resulting in very dry conditions.

Examples of trees that can withstand this heat and drought include Koelreuteria paniculata, Celtis australis, Styphnolobium japonicum, and Gleditsia triacanthos.

A street tree suitable for all conditions is Liquidambar styraciflua. This sweetgum tree has an upright trunk and central leader, as well as healthy, fresh-green foliage that turns shades of purple, purplish-red, red, orange, and yellow in the fall.

Road salt and wind can also play a role on streets. Fruit drop is also undesirable on streets for traffic safety reasons. Several cultivars of the silver linden (Tilia tomentosa) do not drop fruit.

Cultivars of oak (Quercus), poplar (Populus), and sycamore (Platanus) are resistant to road salt.
