Plants
| The following plant lists are based on personal gardening experience in the Rim Country of Arizona, coastal Northern California, Northwestern Washington and the Willamette Valley of Oregon. When the list comes from elsewhere we identify the source for you. |

| 4 Hills Natives |
| These plants grow on Four Hills Ranch, above or in Cataract Canyon and its feeder creeks, between Red Lake and Spring Valley Washes. For reference see U.S.G.S. Topographical Map "Mixen Tank." Non-native, invasive species are not included here. |

| Reforestation Plant Types |
| These are the plants we use in wildland plantings between 4800 and 7200 ft. elevation in the Williams/Tusayan area. They have proved themselves over three years in test plots at Four Hills Preserve. Some varieties (eg. Cupressus arizonica) suffer stunting from late frosts above 5800' elevation. |

| Deer-Proof Plants |
|
The plants in this list tolerate some
browsing, or are so thorny, poisonous or bitter that
a deer rarely returns for another bite.
Install your plants when alternative deer-browse is most plentiful. When food is scarce (late Summer in California, pre-Monsoon in Arizona) deer will browse plants that are toxic or harmful to them. Some plants offer edible growth in spring but back it up with thorns or toxins to limit the depth of the browsing damage (ex. Eleagnus pungens). Deer also may browse a well-hydrated, nursery-fresh plant that would not attract them as a dry, dusty specimen. |

| Plants for High and Dry Gardens |
| Gardens in the mountains of the Western states must contend with hard frosts early and late. Following is a list of plants that can endure these conditions and still make a great show through the Summer and Fall. This list was compiled from an inventory of Flagstaff, AZ gardens, local nurseries and the Flagstaff Arboretum in August 2001. That year the temperature dropped to 16 degrees F. on June 16th. |

| Domestic Weeds |
| Some popular garden plants become unwelcome guests soon after they are introduced to your garden. They become problems as they harbor pests and add to your weeding requirements. Others can jump your fence-lines where they crowd out native plants and choke ravines with their dense cover (eg. Lonicera japonica, Japanese Honeysuckle). |
| List compiled by Four Hills. |
| Acacia decurrens
dealbata
Arundo donax (colonizes creeks, ravines) Cortaderia jubata (invasive in coastal California) Cynodon dactylon (Bermuda grass rhizomes follow all irrigation) Cytisus scoparius, canariensis (Scotch Broom, Canary Island Broom) Eleagnus angustifolia - Russian Olive (invasive in mild-winter climates) Euphorbia characis (invasive in dry gardens) Eragrostis curvula (displaces native prairie species) |

| Walnut Understory |
| Walnuts are allelopathic. They poison the plants that try to live under them. Here is a list of plants that will let you garden in the shade of these great trees of the dry West. |

| Plants for Leach Fields and Septic Mounds |
| These sites require plants with shallow roots and drought-tolerance. You don't want to encourage deep roots here. Trees like Willows, Liquidambers, Eucalypts, Poplars, and Peppers (Schinus) should be ruled out within 50 feet of these sites. |

Arctotheca calendula
|
Bulbs
Amaryllis belladonna
Woody Groundcovers Arctostaphylos uva-ursi
|
| Eucalyptus Understory |
| Like walnuts, Eucalypts reduce their competition for soil nutrients and moisture by killing their neighbors. To do this they hog soil space with a voracious surface root system and, in the case of the giant Blue Gum (Euc. globulus), by smothering their competitors under buckets of tannic leaf and bark litter. |
