Note: Plant names are in the form "common name (scientific name)." Common names, in some cases, link to photos taken at Bull Pasture. Scientific names, that are linked, point to the plant page for that specie.

The most common shrubs here are brittlebush (Encelia farinosa) and jojoba (Simmondsia chinensis). Other conspicuous plants seen are saguaros (Carnegia gigantea), foothill paloverde (Parkinsonia microphylla) and a large organ pipe cactus (Stenocereus thurberi) right at the trailhead. Depending on weather conditions and the time of year, many other species of will be seen.

Waypoint 1: (N32.01625 W112.71151)
Visible plants at Estes Wash, about 0.1 mile from the trailhead, include catclaw acacia (Acacia greggii), canyon ragweed (Ambrosia ambrosioides), creosote bush (Larrea tridentata), a chain-fruit cholla (Opuntia fulgida) to the north and a velvet mesquite (Prosopis velutina) to the south. Other plants that could be seen in washes similar to this include blue paloverde (Parkinsonia florida), desert broom (Baccharis sarothroides), chuparosa (Justicia californica), desert hackberry (Celtis pallida), desert willow (Chilopsis linearis), bitter condalia (Condalia globosa) and graythorn (Ziziphus obtusifolia).

Waypoint 2: (N32.01671 W112.71107)
Trail splits. Left is Estes Canyon Trail and right is Bull Pasture Trail.

Waypoint 3: (N32.01695 W112.70855)
At this point the trail crosses another small wash. It is here where we start seeing Samo Prieto or baby bonnets (Coursetia glandulosa) along the trail. This is a fairly large shrub seen in scattered locations in the Monument but apparently not elsewhere this far west. It displays attractive yellow and pink pea-shaped flowers in March. Samo Prieto (Coursetia glandulosa) will be seen scattered along the trail almost to the overlook. Also desert agave (Agave deserti) will be occasionally seen scattered along the trail.
