Tōgarashi (唐辛子 ) is Japanese for genus "Capsicum", or specifically the species "Capsicum annuum", and commonly translated as chili pepper.
 When the term is used in English, it refers to any number of chili peppers or chili pepper-related products from Japan, including:
Ophiopogon (lilyturf) is a genus of evergreen perennial plants native to warm temperate to tropical east, southeast, and south Asia.
 Despite their grasslike appearance, they are not closely related to the true grasses Poaceae.
 The name of the genus is derived from Greek Όφις "ophis", "snake", and πόγὦν "pogon", "beard", most probably referring to its leaves and tufted growth.
 In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae).
 Like many lilioid monocots, it was formerly classified in the Liliaceae.
Centaurea ( ) is a genus of between 350 and 600 species of herbaceous thistle-like flowering plants in the family Asteraceae.
 Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich.
 Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads" (common knapweed).
 The "Plectocephalus" group – possibly a distinct genus – is known as basketflowers.
 "Cornflowers" is used for a few species, but that term more often specifically means "C. cyanus" (sometimes also called "basket flower").
 The common name "centaury" is sometimes used, although this also refers to the unrelated plant genus "Centaurium".
Capsicum cardenasii is a plant from the Solanaceous family and genus "Capsicum" of plants.
 It is a diploid with 2n=2x=24.
 It is a member within the "C. pubescens" complex, a group of closely related "Capsicum" species.
 It is closely related to "C. eximium".
 It is native to the Andes, and it can be found in Bolivia.
 The native name is ulupica.
The banana pepper (also known as the yellow wax pepper or banana chili) is a medium-sized member of the chili pepper family that has a mild, tangy taste.
 While typically bright yellow, it is possible for them to change to green, red, or orange as they ripen.
 It is often pickled, stuffed or used as a raw ingredient in foods.
 It is a cultivar of the species "Capsicum annuum".
 Its flavor is not very hot (0–500 Scoville units) and, as is the case with most peppers, its heat depends on the maturity of the pepper, with the ripest being sweeter than younger ones.
Crowley Foods (legal name Crowley Foods LLC) is an American dairy company formerly based in Binghamton, New York.
 It has been a subsidiary of HP Hood LLC since being purchased by the company in 2004, which is headquartered in Lynnfield, Massachusetts.
 Products provided by the company include milk, half and half, cream, cottage cheese, sour cream and yogurt.
 The original plant located on Conklin Avenue in Binghamton manufactured these dairy products until the acquisition by HP Hood, when certain Crowley Foods items began to be made at facilities elsewhere which were better equipped.
 Production at the plant ceased altogether in 2012, but the warehouse and distribution center continued to be used until 2014.
Vanilla, the vanilla orchids, forms a flowering plant genus of about 110 species in the orchid family (Orchidaceae).
 The most widely known member is the flat-leaved vanilla ("V. planifolia"), native to Mexico, from which commercial vanilla flavoring is derived.
 It is the only orchid widely used for industrial purposes in flavoring such products as foods, beverages and cosmetics, and is recognized as the most popular aroma and flavor.
 The key constituent imparting its popular characteristics is the phenolic aldehyde, vanillin.
Capsicum annuum is a species of the plant genus "Capsicum" native to southern North America and northern South America.
 This species is the most common and extensively cultivated of the five domesticated capsicums.
 The species encompasses a wide variety of shapes and sizes of peppers, both mild and hot, such as bell peppers, jalapeños, and cayenne peppers. Cultivars are descended from the wild American bird pepper still found in warmer regions of the Americas.
 In the past some woody forms of this species have been called "C. frutescens", but the features that were used to distinguish those forms appear in many populations of "C. annuum" and it is not a consistently recognizable feature in "C. frutescens" species.
 Moreover, crosses between C.annuum and C. frutescens aren't likely because seeds obtained from polliations between those two species (if the embryo survives) will not germinate.
Capsicum ( ; also known as peppers) is a genus of flowering plants in the nightshade family Solanaceae.
 Its species are native to the Americas, where they have been cultivated for thousands of years.
 Following the Columbian Exchange, it has become cultivated worldwide, and it has also become a key element in many cuisines.
 In addition to use as spices and food vegetables, "Capsicum" species have also been used as medicines and lachrymatory agents.
Anthriscus or chervil is a common plant genus of the family Apiaceae, growing in Europe and temperate parts of Asia.
 It comprises 15 species, some of which are considered as noxious weeds .
 The genus grows in meadows and verges on slightly wet porous soils.
 One species, "Anthriscus cerefolium" is cultivated and used in the kitchen to flavor foods.
