Trifolium repens, the white clover (also known as Dutch clover, Ladino clover, or Ladino), is a herbaceous perennial plant in the bean family Fabaceae (Previously referred to as Leguminosae).
 It is native to Europe and central Asia.
 One of the most widely cultivated types of clover, it has been widely introduced worldwide as a forage crop, and is now also common in most grassy areas (lawns and gardens) of North America and New Zealand.
 The species includes varieties often classed as small, intermediate and large, according to height, which reflects petiole length.
 The term “white clover” is applied to the species in general, “Dutch clover” is often applied to intermediate varieties (but sometimes to smaller varieties), and “ladino clover” is applied to large varieties.
Rajagopalan Krishnamurthy (born 27 March 1928) is one of the authorities on cotton research in India.
 He is a prolific Indian plant breeder who introduced a myriad of cotton varieties for commercial cultivation.
 He served in the Department of Agriculture of Tamil Nadu for one decade and almost 28 years in Indian Council of Agricultural Research (ICAR).
 He has released as many as 6 varieties from G. Hirsutum, two from G. Barbadense and three hybrids during his tenure in ICAR Service.
 All of them are prominent and accepted by the farmers as well as the textile mills at Tamil Nadu and elsewhere.
 He completed B. Sc.
(Agri.)
 and M. Sc.
 (Agri.)
 in plant breeding and genetics from Tamil Nadu Agricultural University, Coimbatore.
 He is also the Research Director - Cotton of Rasi Seeds Pvt. Ltd.
Schwantesia constanceae is a species of plant in the Aizoaceae family.
 It is endemic to Namibia.
 Its natural habitat is rocky areas.
 It is threatened by habitat loss.
Campsis radicans (trumpet vine or trumpet creeper, also known in North America as cow itch vine or hummingbird vine), is a species of flowering plant of the family Bignoniaceae, native to the eastern United States and naturalized in parts of the western United States as well as in Ontario, parts of Europe, and scattered locations in Latin America.
 Growing to 10 m , it is a vigorous, deciduous woody vine, notable for its showy trumpet-shaped flowers.
 It inhabits woodlands and riverbanks, and is also a popular garden subject.
Paprika (US English more commonly , British English more commonly ) is a ground spice made from red air-dried fruits of the larger and sweeter varieties of the plant "Capsicum annuum", called "bell pepper" or "sweet pepper", sometimes with the addition of more pungent varieties, called "chili peppers", and cayenne pepper.
 In many languages, but not English, the word "paprika" also refers to the plant and the fruit from which the spice is made.
Packera bolanderi is a species of flowering plant in the aster family known by the common names Bolander's ragwort and seacoast ragwort.
 It is native to the west coast of the United States from Washington to northern California, where it grows in wet coastal forests and woodlands.
 There are two varieties of the species which differ slightly in morphology and habitat occupied; these varieties have been considered separate species by some authors.
 The var.
 "bolanderi" has thicker leaves, occurs farther south (into California), and occupies more open types of habitat, than does var.
 "harfordii".
 This plant in general is a perennial herb producing one to three stems up to half a meter tall.
 The basal leaves have blades up to 12 centimeters long which are divided into several lobes and borne on long, thin petioles.
 Leaves growing farther up the stem are smaller and have more lobes on their blades.
 The inflorescence contains several flower heads, each lined with dark green phyllaries.
 The head contains many golden yellow disc florets and generally either 8 or 13 yellow ray florets each over a centimeter long.
 The fruit is an achene tipped with a pappus of bristles.
Campsis (trumpet creeper, trumpet vine) is a genus of flowering plants in the family Bignoniaceae, native to woodland in China and North America.
 It consists of two species, both of which are vigorous deciduous perennial climbers, clinging by aerial roots, and producing large trumpet-shaped flowers in the summer.
 They are hardy but require the shelter of a warm wall in full sun.
Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals or radiation in order to generate mutants with desirable traits (or lacking undesirable ones) to be bred with other cultivars.
 Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
 From 1930 to 2014 more than 3200 mutagenic plant varieties were released that have been derived either as direct mutants (70%) or from their progeny (30%).
 Crop plants account for 75% of released mutagenic species with the remaining 25% ornamentals or decorative plants.
 However, although the FAO/IAEA reported in 2014 that over 1,000 mutant varieties of major staple crops were being grown worldwide, it is unclear how many of these varieties are currently used in agriculture or horticulture around the world, as these seeds are not always identified or labeled as being mutagen or having a mutagenic provenance.
A garden grown specifically for the purpose of testing and evaluating plants is called a trial garden.
 Universities, plant breeders, and garden-industry companies frequently have trial gardens, as do many private and public botanical gardens and professional garden journalists.
 In the classic trials model, newly developed varieties of plants are compared with the closest similar industry standard plant throughout their life cycle—from germination/propagation through maturity, from seed to harvest.
 By growing new varieties side-by-side with existing ones, researchers can determine whether these new varieties are indeed better, and, if so, in what respects.
Schwantesia is a genus of plant in the family Aizoaceae.
 It is named in honor of the German botanist and archaeologist Gustav Schwantes (1881 - 1960).
