Penstemon Whippleanus
''Penstemon whippleanus'', commonly known as dusky penstemon, dusky beardtongue, Whipple's penstemon, or Whipple's beardtongue, is a summer blooming perennial flower in the large ''Penstemon'' genus. It is a widespread plant within the hemiboreal forests of the Rocky Mountains in North America. It is noted for the large deep purple-red flowers and a preference for high mountain elevations. Description This species is distinctive in its range and mountain habitat for the size and color of its flowers and the height of its flowering stems, usually 20–65 cm. Though it has been recorded as growing up to 100 cm in height in unusually favorable conditions. Like most members of its genus, ''Penstemon whippleanus'' is an evergreen perennial plant. They have both leaves at the base of the plant (basal leaves) and in pairs on opposite sides of their flowering stems. The basal leaves grow on short stems, are smooth without hairs, but not leathery. Each basal leaf is about 40– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botany, botanist of the 19th century. His ''Darwiniana'' (1876) was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built a ...

Flora Of Montana
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Stratification (seeds)
In horticulture, stratification is a process of treating seeds to simulate natural conditions that the seeds must experience before germination can occur. Many seed species have an embryonic dormancy phase and generally will not sprout until this dormancy is broken. The term stratification can be traced back to at least 1664 in John Evelyn's ''Sylva, or A Discourse of Forest-Trees and the Propagation of Timber'', where seeds were layered (stratified) between layers of moist soil and the strata were exposed to winter conditions. Thus, stratification became the process by which seeds were artificially exposed to conditions to encourage germination. Cold stratification Cold stratification is the process of subjecting seeds to both cold and moist conditions. Seeds of many trees, shrubs and perennials require these conditions before germination will ensue. In the wild, seed dormancy is usually overcome by the seed spending time in the ground through a winter period and having its har ...

Division (horticulture)
Division, in horticulture and gardening, is a method of asexual plant propagation, where the plant (usually an herbaceous perennial) is broken up into two or more parts. Each part has an intact root and crown. The technique is of ancient origin, and has long been used to propagate bulbs such as garlic and saffron. Another type of division is through a plant tissue culture. In this method the meristem (a type of plant tissue) is divided. Overview Division is one of the three main methods used by gardeners to increase stocks of plants (the other two are seed-sowing and cuttings). Division is usually applied to mature perennial plants, but may also be used for shrubs with suckering roots, such as gaultheria, kerria and sarcococca. Annual and biennial plants do not lend themselves to this procedure, as their lifespan is too short. Practice Most perennials should be divided and replanted every few years to keep them healthy. Plants that do not have enough space between them will sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Resources Conservation Service
Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers. Its name was changed in 1994 during the presidency of Bill Clinton to reflect its broader mission. It is a relatively small agency, currently comprising about 12,000 employees. Its mission is to improve, protect, and conserve natural resources on private lands through a cooperative partnership with State governments of the United States, state and Local government in the United States, local agencies. While its primary focus has been agriculture, agricultural lands, it has made many technical contributions to soil surveying, soil classification, classification, and water quality improvement. One example is the Conservation Effects Assessment Project (CEAP), set up to quantify the benefits of agricultural conservation efforts pr ...

David D
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and ''Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; page 32 ...

Rabbit Ears Pass
Rabbit Ears Pass (el. 9426 ft, 2873 m) is a high mountain pass in the Rocky Mountains of northern Colorado in the United States, where U.S. Route 40 crosses the Park Range (Colorado). North of the summit is Rabbit Ears Peak which has the shape of rabbit ears, which displays two large columns of Basalt, basalt rock formations from the second volcanic episode. Rabbit Ears Peak is underlain by a pink tuff and the basalt immediately to the west is underlain by red, vesicular ash. Breccia, Volcanic breccia occurs only at the Peak, which is a large stratified breccia pile. The three basal layers are cut by a basalt dike immediately beneath the peak. From petrographic evidence there appears to have been one period of lava flows and this surface can be seen at Rabbit Ears Peak. The Rabbit Ears Pass area covers 56 square miles in north central Colorado at the junction of the Rabbit Ears Range and the Park Range. The Rabbit Ear Pass highway, which is one of the most important t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
