It is native to stony and sandy plains in the Mojave Desert of California and the Sonoran Deserts of the Southwestern United States northwestern Mexico. It is and is very common in the northern, eastern, and southern parts of the desert. Monoptilon bellioides is a short annual plant; in seasons with very little rainfall, the plant may only grow to 1-2 cm, if it grows at all, while in seasons of heavy rainfall, it can grow up to 25 cm tall. The leaves are linear, 5-10 mm long, with a blunt apex. The flowers are produced in dense inflorescences (capitula), 2 cm diameter, with white ray florets and yellow disc florets in the center. The flowers open in the morning and close in the evening.

Monotropa hypopitys - called Dutchman's pipe, false beech-drops, pinesap, or yellow bird's-nest - is a herbaceous perennial plant, formerly classified in the families Monotropaceae or Pyrolaceae, but now included within the subfamily Monotropoideae of the blueberry family (Ericaceae). It is native to temperate regions of the Northern Hemisphere, and is scarce or rare in many areas. However, it is still the most widespread member of the subfamily. While currently included in the genus Monotropa, recent genetic evidence strongly suggests that Monotropa hypopitys should be placed in its own genus, Hypopitys, with the single species Hypopitys monotropa Crantz, but possibly containing several other species. Unlike most plants, it does not contain chlorophyll; it is a myco-heterotroph, getting its food through parasitism upon fungi rather than photosynthesis. These fungi form a mycorrhiza with nearby tree species.

Monotropa uniflora, also known as the ghost plant, Indian pipe, or corpse plant, is a herbaceous perennial plant native to temperate regions of Udmurtiya in European Russia, Asia, North America and northern South America, but with large gaps between areas. It was formerly classified in the family Monotropaceae; however, it has now been included within the Ericaceae. It is generally scarce or rare in occurrence. Unlike most plants, it is white and does not contain chlorophyll. Instead of generating energy from sunlight, it is parasitic, more specifically a myco-heterotroph. Its hosts are certain fungi that are mycorrhizal with trees, meaning it ultimately gets its energy from photosynthetic trees. Since it is not dependent on sunlight to grow, it can grow in very dark environments as in the understory of dense forest. It is often associated with beech trees. The complex relationship that allows this plant to grow also makes propagation difficult.

Montia chamissoi is a species of flowering plant in the purslane family known by the common names of water minerslettuce, water montia, Indian lettuce, and toad lily. It is native to much of western North America from Alaska to the southwestern and central United States and also in British Columbia. It grows in moist to wet soils in a variety of habitat types, such as meadows, wetlands, plains, and montanes (Kershaw et al., 1998). It is sometimes aquatic, anchoring in mud and floating in water. M. chamissoi appears between 7,000 to 9,000 feet in elevation (Brussard, 1982). and are endemic to western North America. Wetlands, montanes, and prairie zones are where M. chamissoi thrive. They occur in the Rocky Mountain region, Pacific Alaska Region, Pacific Region, and even in part of the mid-atlantic and great lakes region. They are also highly prevalent in Canada including Alberta and British Columbia. It can also grow on the dry slopes of the plains and foothills creating a huge distribution. It is found along coastal areas but this is mostly rare (Brussard, 1982). Related Species. Related taxa involves 10 genera in Portulacaceae and 9 species in Montia. A few genera related are spring beauty ( Claytonia L. ), fame flower (Talinum adans. ), and red maids (Calandria kunth). Like M. chamissoi these genera have very large distributions and stamens. Montia fontana and Motia parvifolia are two relating species that involve wide distributions but differ in the fact that the distributions are higher in elevation and take up most of Canada and Greenland.

Brussard noted that there have been failures and success when trying to preserve M. chamissoi due to mining development that has lowered small M. chamissoi populations in the United States (Brussard, 1982). Brussard (1982) observed that a population of M. chamissoi was destroyed by road construction near a ski area and it was also noted that this was the only known population in Gunnison County, Colorado. This led to an increase in Rocky Mountain Biological Laboratories and helped establish the laboratory' claim to undisturbed habitat as a natural resource (Brussard, 1982). It is also a rare plant species in British Columbia and is a candidate species for restoration and preservation. (Rose & Burton, 2011). Even though, M. chamissoi has a very wide distribution it is currently listed on the endangered list in Minnesota and Pennsylvania and is in the progress of restoration

Bull grass (Muhlenbergia emersleyi) is a grass valued for both wildland restoration and water-wise landscapes. In California it holds a California Rare Plant Rank of 2B.2, meaning it is rare, threatened, or endangered in the state but more common elsewhere. It is known from only a few occurrences in the Santa Rosa and San Jacinto mountains of Riverside County, where it grows in relatively specialized conditions.

This perennial bunchgrass forms dense, upright clumps of blue-green to pale green foliage, typically reaching 2–3 feet tall and about as wide. Narrow leaves arise from the base, creating a tidy mound that works well in naturalistic plantings. In late summer to fall, bull grass produces open, airy panicles with purplish to tan flower spikes that catch the light and add subtle movement and texture to the landscape.

In the wild, bull grass is found in montane chaparral and along washes or rocky slopes with seasonally available moisture. It often flowers in response to summer monsoon rains, which partly explains why it was documented relatively late by botanists. In gardens, it is drought-adapted once established and performs best in full sun to part shade with well-drained soils. It is well suited to meadow plantings, slope stabilization, and habitat gardens where a soft, natural look is desired.

To maintain a healthy, attractive clump, cut plants back hard to about 6 inches from the ground in April to refresh growth, or cut back every few years to remove accumulated dead material.

Myriophyllum verticillatum, the whorl-leaf watermilfoil or whorled water-milfoil, is a native to much of the North America, North Africa, and Eurasia. It closely resembles another native milfoil, called northern water milfoil (M. sibiricum) Whorled water milfoil is also easily confused with four types of invasive milfoils: Eurasian water milfoil (M. spicatum), Variable water-milfoil (M. heterophyllum), Parrot feather (M. aquaticum), and hybrid water milfoil (M. heterophyllum X M. laxum). In many areas it is an invasive aquatic plant. It is native in much of North America, the United Kingdom, Asia, and North Africa, and invasive to Ireland. Propagation and reproduction. Whorled water-milfoil reproduces by producing turions between September and November each year. These over-wintering turions sink to the bottom of the floor where they remain dormant until February [Caffrey,2006]. These fragments will give rise to numerous small thin roots that bed into soil to start growing in spring. The plants are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by wind. Control and uses. Whorled water milfoil is a good water oxygenator in small quantities such as fish and frog ponds. It is also ideal in providing protection and respiration for fish spawn Management techniques of whorled water milfoil are not exactly known, but natural competition with other invasive aquatic plants has been the main control so far. There are a few management practices that some places are using, but they have not been approved for long-term usage.
