Why Go Native?
Arborist Pat Hoff teaches about Native Trees
Native plants and trees need less water and chemicals than non-native species, are more resistant to pests and diseases, and also attract birds, butterflies and other beneficial wildlife to your yard. Simultaneously, they also reduce erosion and protect water quality. Help keep our rivers clean and watershed healthy by planting a native on your property. The City’s commitment to bringing native species to Beaverton has been growing over many years. To continue promoting native species, the City's Public Works department will highlight a native plant each month for home and business owners to consider when working outdoors. Keep in mind; it is the home and business owners’ responsibility to maintain street trees located within the right-of-way adjacent to their properties.
Beaverton's Native Plant of the Month: Ponderosa pine
Common Name: Ponderosa pine
Binomial Name: Pinus ponderosa
Soil Type: Well drained, moist to fairly dry
Sunlight: Full sun
Plant Type: Evergreen tree
Form: Upright straight trunk
Foliage: Needles (in bundles of 3)
The best way to determine a ponderosa pine from the many other types of pine trees is by counting the needles they are usually in groups of three and extra-long (9 to 11 inches). Another way of identifying is the bark, when young the bark is blackish in color, when they are mature the bark develops deep grooves with flaky orange bark and deep black grooves.
The ponderosa pine is a moderate to fast grower and can reach heights of 50 to 100 feet tall in urban settings and around 200 feet tall in the wild. Often grown as bonsai trees or planted in tall groves these trees are not very picky about soil types as long as it is on the dry side. The thick bark makes these trees very fire-resistant and decay-resistant in forest settings.
Ponderosa pines can be seen filling the sky line all over Beaverton, But Beaverton’s “city park” near the library at 5th street and Watson Street is one of the most popular places to see the big ponderosa’s.
