Populus fremontii, commonly known as Frémont's cottonwood, [1] is a cottonwood (and thus a poplar) native to riparian zones of the Southwestern United States and northern through central Mexico. [2] It is one of three species in Populus sect. Aigeiros. The tree was named after 19th-century American explorer and pathfinder John C. Frémont.
In riparian areas (streamside and moist habitats) some of the trees include: California sycamore (Platanus racemosa) White alder (Alnus rhombifolia) Quaking aspen (Populus tremuloides) Fremont cottonwood (Populus fremontii) Black cottonwood (Populus trichocarpa) Arroyo willow (Salix lasiolepis) [10]
They are large, deciduous trees that are 15–30 m (50–100 ft) tall and diameters of 4 m (13 ft), [2] distinguished by thick, deeply fissured bark and triangular-based to diamond-shaped leaves that are green on both sides (without the whitish wax on the undersides) and without any obvious balsam scent in spring.
The plant is a flowering evergreen hardwood shrub or small multi-trunked tree, growing from 2.4–5.5 metres (8–18 ft) in height and 1.8–3.0 m (6–10 ft) in width. The 1–5 cm (3 ⁄ 8 –2 in) leaves are olive to gray−green, fuzzy and flannel-like, palmately to pinnately lobed. The hairs covering the leaves are easily brushed off in ...
Poplars of the cottonwood section are often wetlands or riparian trees. The aspens are among the most important boreal broadleaf trees. [2] Poplars and aspens are important food plants for the larvae of a large number of Lepidoptera species. Pleurotus populinus, the aspen oyster mushroom, is found exclusively on dead wood of Populus trees in ...
There are several types of riparian forest, the South Fork Valley has the Great Valley Cottonwood Forest, distinguished by a majority of Fremont cottonwood and willow tree species. The understory is dense with wild rose and shade-tolerant Oregon ash. The soils are fine-grained alluvial with annual river flooding that maintains fertility.
