Please answer the following question: Information: - Berry Botanic Garden was a botanical garden in southwest Portland, Oregon, in the United States. In addition to large collections of alpine plants, rhododendrons, primulas, lilies, it was known for its plant-conservation program and its large seed bank that protects rare or endangered plants of the Pacific Northwest. The seed bank, formally established in 1983, was thought to be the first in the U.S. that was devoted entirely to preserving rare native plants. - The Willamette River is a major tributary of the Columbia River, accounting for 12 to 15percent of the Columbia's flow. The Willamette's main stem is long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia. - Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. Alpine plants grow together as a plant community in alpine tundra. Alpine plants are not a single taxon. Rather, many different plant species live in the alpine environment. These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. Alpine plants must adapt to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season. - A flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds. - Primula is a genus of mainly herbaceous flowering plants in the family Primulaceae. They include the familiar wildflower of banks and verges, the primrose ("P. vulgaris"). Other common species are "P. auricula" (auricula), "P. veris" (cowslip) and "P. elatior" (oxlip). These species and many others are valued for their ornamental flowers. They have been extensively cultivated and hybridised - in the case of the primrose, for many hundreds of years. "Primula" are native to the temperate northern hemisphere, south into tropical mountains in Ethiopia, Indonesia and New Guinea, and in temperate southern South America. Almost half of the known species are from the Himalayas. - Lomatium bradshawii , also known as Bradshaw 's desert parsley , is an endangered perennial herb native to Oregon and Washington , United States . Lomatium bradshawii was thought to be extinct until 1979 , when it was rediscovered by a University of Oregon graduate . This herb was common in the Willamette Valley before agricultural development and fire prevention which has allowed shrubs and weeds to invade . Most known populations of Lomatium bradshawii are within ten miles of Eugene , Oregon . In the Willamette Valley , populations exist in the Oregon counties Lane , Benton , Linn , and Marion , and in Washington Lomatium bradshawii grows in Puget Sound . The Nature Conservancy cares for the largest population of this herb , with over 10,000 plants , and the Berry Botanic Garden keeps a seedbank . Lomatium bradshawii grows in low elevations along rivers or in regularly flooded prairies . Yellow inflorescences of Lomatium bradshawii occur from April to May . - The University of Oregon (also referred to as UO or Oregon) is a public flagship research university in Eugene, Oregon. Founded in 1876, the institution's 295-acre campus is along the Willamette River. Since July 2014, UO has been governed by the Board of Trustees of the University of Oregon. The university has a Carnegie Classification of "highest research activity" and has 21 research centers and institutes. UO was admitted to the Association of American Universities in 1969. - A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem. The leaves and stem together form the shoot. Leaves are collectively referred to as foliage, as in "autumn foliage." - Rhododendron (from Ancient Greek "rhodon" "rose" and "dendron" "tree") is a genus of 1,024 species of woody plants in the heath family (Ericaceae), either evergreen or deciduous, and found mainly in Asia, although it is also widespread throughout the Southern Highlands of the Appalachian Mountains of North America. It is the national flower of Nepal. Most species have showy flowers which bloom from late winter through to early summer. - A flagship is a vessel used by the commanding officer of a group of naval ships, characteristically a flag officer entitled by custom to fly a distinguishing flag. Used more loosely, it is the lead ship in a fleet of vessels, typically the first, largest, fastest, most heavily armed, or best known. - The Pacific Northwest (in the United States, commonly abbreviated as PNW), sometimes referred to as Cascadia, is a geographic region in western North America bounded by the Pacific Ocean to the west and loosely, by the Rocky Mountains on the east. Though no agreed boundary exists, a common conception includes the U.S. states of Oregon and Washington and the Canadian province of British Columbia. Broader conceptions reach north into Alaska and Yukon, south into far northern California and east to the Continental Divide, thus including Idaho, Western Montana, and western Wyoming. Narrower conceptions may be limited to the northwestern US or to the coastal areas west of the Cascade and Coast mountains. The variety of definitions can be attributed to partially overlapping commonalities of the region's history, geography, society, and other factors. - In general use, herbs are any plants used for food, flavoring, medicine, or fragrances for their savory or aromatic properties. Culinary use typically distinguishes herbs from spices. "Herbs" refer to the leafy green or flowering parts of a plant (either fresh or dried), while "spices" are produced from other parts of the plant (usually dried), including seeds, berries, bark, roots and fruits.
