Davis Mountains State Park receives more rain than the surrounding desert. A variety of trees are found here, such as Mexican pinyon (Pinus cembroides), Emory oak (Quercus emoryi), gray oak (Quercus grisea) and one-seed juniper (Juniperus monosperma). Shrubs such as scarlet bouvardia (Bouvardia ternifolia), little-leaf leadtree (Leucaena retusa), trompillo (Ipomoea hederifolia), evergreen sumac (Rhus virens), fragrant sumac (Rhus aromatica), Apache plume (Fallugia paradoxa), little walnut (Juglans microcarpa), tree cholla (Cylindropuntia imbricata), Torrey yucca (Yucca torreyi), catclaw acacia (Acacia greggii), and agarita (Mahonia trifoliolata) abound. The high elevations above sea level, not in the park, boast ponderosa pine (Pinus ponderosa) and quaking aspen (Populus tremuloides).
