Parks & Recreation Suggested Woody Understanding Santa Fe’s Desert Vegetation This is a working draft list of plants that can reasonably be expected to grow acceptably in the Santa Fe area, given proper siting and care. Some of these have limited availability at this time, though supplies are increasing. There are others that might grow equally well here, but they have been excluded at this time due to their even more limited availability. This list will be reviewed and modified periodically as potentially useful plants are introduced or become more readily available, and new information about plants currently on the list is developed. This list is not intended to be used to limit selection, but to serve as a guide for those who want to know more about reasonable choices for this area. For those who wish to experiment with plants not listed here, we urge you to find out all you can about the plants’ expected hardiness, cultural requirements, and potential problems. The plants are listed in columns by Latin name, common name, water needs, cautions, and comments. When the terms “cultivars”, “selections” and “forms” are used, it indicates that there is more than one variety of that type of plant sold. Water needs are given for most plants as a range, since soil type, microclimates, type of irrigation, and many other variables can affect the water requirements of plants on a specific site. The irrigation frequencies suggested are only a guideline meant to be used after new plantings are well established, typically from the third season on. Large may need more frequent supplemental irrigation for additional years before these guidelines apply. The suggested watering frequencies are meant to be applied during dry spells when there is no significant natural precipitation. The categories are as follows: VL (Very Low) is for plants that require little or no supplemental irrigation to grow acceptably once they are established. Most of these are native to our environment.

Page 1 Parks & Recreation Suggested Woody Plants

The next category, L (Low), is for plants that need some supplemental irrigation to remain pest and disease free and reach their highest potential in the landscape. They grow well with relatively infrequent irrigation, typically every three to four weeks through the growing season. The third category, M (Moderate), is for plants that need regular irrigation to grow well here, typically every week or two during the growing season. These plants may also need supplemental irrigation monthly during dry winters. For most landscape applications, we recommend using plants with water requirements in these first three categories. The last category, H (High), is for plants that typically grow in areas with much more natural precipitation or available groundwater than is common in Santa Fe. These plants should be used sparingly, and only in areas where site variables like runoff patterns, mulch applications and shade/wind protection can help lessen their water needs, or in streamside areas where water is naturally available. They will usually need to be watered at least once a week during the growing season and at least once a month in dry winters to stay healthy. Caution categories are listed to help alert plant buyers to potential problems that certain plants may develop, especially if they are not sited in favorable locations and maintained in good health. The importance of matching the plant to the conditions of the site cannot be overstated; the right plant in the right place is naturally healthier and more pest and disease resistant. If you want to use plants with cautions applied to them, investigate what is meant by the caution category and what that means in regard to using the plants on your site. The caution categories are as follows: “Al” stands for alkaline- sensitive; these plants may develop iron and other trace mineral deficiencies and grow very poorly (or even die) in soils which are highly alkaline. Page 2 Parks & Recreation Suggested Woody Plants

“Exp” is used to note plants considered experimental in Santa Fe. Some of these are new introductions to the nursery trade, while others have not been used widely enough or long enough in the Santa Fe area to know what their cultural limits and needs are here. The next caution category is labeled “I” for plants which tend to be invasive under certain conditions. Though many plants naturally spread to form clumps, these plants can easily get out of hand in certain locations and crowd out or overrun other plants near them. Some of these are useful for stabilizing slopes and rough areas, but they must be sited very carefully. The notation “P/D” stands for pest/disease potential. Plants marked with this notation have a high likelihood of developing problems with significant pests and/or diseases when they are grown under less than optimal conditions. Plants marked “Sh” are those which either grow naturally in shadier environments or are easier to grow here when they are planted where they receive some shade, especially afternoon shade. The plants in this group also typically do best in locations where they are sheltered from high winds and heat-reflecting surfaces. These are not plants to be used in hot, dry environments.

The Comments section includes other information useful in helping to decide whether or not to use certain plants. Compiled by Tracy Neal. Consulting Horticulturist. Santa Fe, .
