Question: Are Onions and Jamesia both shrubs?

Context paragraphs:
Fried onion: Fried onions or French fried onions are a popular snack food, garnish, or vegetable accompaniment to various recipes.  Common fried onions are cooked by basic pan frying or sautéing of sliced onions.  This produces a fairly soft cooked onion, which may brown some from a Maillard reaction, depending on the length of cooking and the temperature.  The Philadelphia cheesesteak is a hot sandwich commonly served with sautéed onions, and they are half of the dish called liver and onions.  In the Middle East Mujaddara is a dish made of lentils and rice topped with fried onions.  In Indian cuisine, fried onions are one of the key ingredients for the rice dish called biryani.

Jamesia: Jamesia is a genus of shrubs in the Hydrangeaceae, most commonly known as Jamesia, cliffbush or waxflower.  It is native to interior western North America, in the U.S. states of Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming, growing in mountains at 1600–3000 m altitude.

Michigan hot dog: A Michigan hot dog, or simply "Michigan", is a steamed hot dog on a steamed bun topped with a meaty sauce, generally referred to as "Michigan sauce".  The sauce may be tomato-based, depending on where the Michigan is purchased.  Michigans can be served with chopped onions.  If served with onions, the onions can either be buried under the sauce, under the hot dog itself, or sprinkled on top of the sauce.

Onion: The onion ("Allium cepa" L., from Latin "cepa" "onion"), also known as the bulb onion or common onion, is a vegetable and is the most widely cultivated species of the genus "Allium".  Its close relatives include the garlic, shallot, leek, chive, and Chinese onion.

Tree onion: Tree onions, topsetting onions, walking onions, or Egyptian onions, "Allium" × "proliferum", are similar to common onions ("A. cepa"), but with a cluster of bulblets where a normal onion would have flowers.  Genomic evidence has conclusively shown that they are a hybrid of the common onion and the Welsh onion ("A. fistulosum").  However, some sources may still treat the tree onion as "A. cepa" var.  "proliferum" or "A. cepa" Proliferum Group.

Dopiaza: Dopiaza (Persian: دوپیازه meaning "two onions") is a Middle Eastern dish from Afghan cuisine.  It is prepared with a large amount of onions, both cooked in the spices and curry and as a garnish.  Onions are added at two stages during cooking, hence the name ("two onions" Dari).  The dish usually contains a meat, usually beef, chicken, lamb, mutton, or shrimp; however, it can also be prepared in a vegetarian style.

Cocktail onion: A cocktail onion is usually a pearl onion pickled in a brine with small amounts of turmeric and paprika.  Pearl onions are naturally sweet, which makes them an excellent pairing with many cocktails.  Other sweet onions such as the crystal wax, also known as the white Bermuda, are also sometimes used.  In many cases, white varieties of these sweet onions are used, since many consumers expect cocktail onions to be white.  However, yellow or red sweet onions may be used as well.  In northern California cuisine some haute bars may use sliced red onion pickled in vinegar.  Some recipes also call for the onions to be packed in white vermouth as well as vinegar.

Lunumiris: Lunumiris (Sinhala:ලුණු මිරිස් [lunu-miris] some also refer it as "Katta Sambal" [Sinhala:කට්ට සම්බෝල [kaṭṭa sambōla]]) is a spicy Sri Lankan sambal paste served as a condiment.  It consists of chili pepper, red onions, Maldive fish, sea salt, black pepper and lime juice, usually ground with mortar and pestle or grind stone.  However red onions aren't used when making katta sambal, and red onions is used in lunu miris so lunu miris has a more wet texture than katta sambal.

Liver and onions: Liver and onions is a dish consisting of slices of liver (usually pork, beef or, in the United Kingdom, lamb) and onions; onion is favoured as an accompaniment to liver as the flavour of onion "cuts" the somewhat metallic flavour of liver, which can be off-putting to some eaters.  The liver and the onions are usually fried or cooked together, but sometimes they may be fried separately and mixed together afterwards.  The liver is often cut in fine slices, but it also may be diced.

Pickled onion: Pickled onions are a food item consisting of onions (cultivars of "allium cepa",) pickled in a solution of vinegar and salt, often with other preservatives and flavourings.  In the United Kingdom they are often eaten alongside fish and chips or as part of a ploughman's lunch.  There is a variety of small white pickled onions known as 'silverskin' onions, due to imperfections they are pickled instead of being wasted.  They are frequently used as an essential component of the Martini cocktail variant known as a Gibson.
