RECOMMENDED PLANTS

This list provides guidance when selecting plants for your landscape design project. The City’s Landscape Regulations state: “Landscaping materials are intended to contribute to the community-wide goals of beautification, energy conservation, and the conservation of the community’s water resources through the use of drought tolerant plants, efficient irrigation, reduced turf areas, and proper maintenance and the fundamentals of xeriscape landscaping.” Listed species are particularly well-adapted to Yuma’s climate and have low to moderate water use needs. In addition to low water use, the information provided in the tables describes the basic growth characteristics and maintenance requirements of each plant, including the following:

Water Use: All plants included in this list are low-water-use species, but the Water Use column identifies the most water-conscious varieties. Each plant is classified as Low (L), Low to Moderate (L-M), or Moderate (M). Trees classified as Moderate water use will thrive in grassy areas with sprinkler irrigation. Litter: All plants produce litter when flowers, seedpods, or leaves drop, but some plants produce more than others. Each species is classified as producing minimal (MIN), moderate (MOD), or high (HI) litter. Carefully consider the placement of high-litter plants as they do require more maintenance. Pruning Season: Most plants need to be pruned only once a year. The best season to prune each species differs based on when it flowers, goes dormant, and other factors. Some species, particularly succulents and cactus, do not need to be pruned. Hardiness: The number shown indicates the lowest temperature the plant is known to tolerate. Evergreen: Evergreen plants (Y) leaf throughout the year, while deciduous plants (N) drop their leaves in the winter months. Semi-evergreen plants (SEMI) drop their leaves for a short period with sufficiently cold temperatures.
