Rose trial grounds or rose test gardens are agricultural areas where garden roses are grown to be assessed for qualities such as health, floriferousness, novelty, and scent.
Roses on trial are usually considered for awards of merit or medals at the end of the trial period. Roses that win an award may be more likely to have commercial success. Forty per cent of all roses sold in the U.S. have won All-America Rose Selections. [1] [2] Similarly, the UK Rose of the Year award usually guarantees that a particular variety will be widely available at garden centres and through mailorder rose suppliers. [3]
Typically, roses are grown for two years in a test area (usually a dedicated rose bed) to judge them over a period of time, In the UK the trial grounds are, from 2020, at Rochfords in Hertford, where the new roses are judged on the trial grounds over a three-year growing period.[ citation needed ] In the United States the All-America Rose Selections (AARS), which were first introduced in 1938, [4] were awarded annually until 2013 based on the results of testing in 21 gardens across the US over a two-year period. Roses which scored highly across all judging areas in a variety of climates were awarded this national award. [1] Since 2013, two separate multi-site rose trialing programs have emerged. The first, the American Garden Rose Selections (AGRS) is very similar to AARS, while the second, the American Rose Trials for Sustainability (ARTS) takes a thoroughly scientific approach. [5] Another multi-site trial is the ADR in Germany.
In most cases, roses are identified by a number during the trial period, with their identity not revealed until after final judging. A local panel of judges may assess them throughout the trial period, although at some trials there may be an invited national or international panel. Roses are generally judged within a category, such as Hybrid Tea, Floribunda, or patio rose, to fairly compare like styles. There are specific awards for fragrance, which are judged across all categories.
Parc de Bagatelle in Paris hosted the first international competition in 1907. This event, known as the Concours international de roses nouvelles de Bagatelle (International competition for new roses), has taken place annually ever since and remains one of the world's top rose competitions. [6] [7]
A formalised international rose trial scheme was established in 1928 by the Royal National Rose Society (then known as the National Rose Society) in Britain, although the society had been awarding gold medals to the best new roses grown by its membership since 1883. [6] [8]
Over succeeding decades, trial grounds have been established in most major rose growing countries. Often they are located in botanic gardens and parks. Some countries have several trial grounds to assess roses in a variety of climates and soils. The first rose trial ground in the southern hemisphere (where rose seasons and growing conditions may be very different from the northern hemisphere) was established in New Zealand in 1969 as a partnership between the national rose society and Palmerston North city council. [9]
Rose trial grounds involved with major rose awards include:
The International Rose Test Garden is a rose garden in Washington Park in Portland, Oregon, United States. There are over 10,000 rose bushes of approximately 650 varieties. The roses bloom from April through October with the peak coming in June, depending on the weather. New rose cultivars are continually sent to the garden from many parts of the world and are evaluated on several characteristics, including disease resistance, bloom formation, color, and fragrance. It is the oldest continuously operating public rose test garden in the United States and exemplifies Portland's nickname, "City of Roses". The garden draws an estimated 700,000 visitors annually.
The Bois de Boulogne is a large public park that is the western half of the 16th arrondissement of Paris, near the suburb of Boulogne-Billancourt and Neuilly-sur-Seine. The land was ceded to the city of Paris by the Emperor Napoleon III to be turned into a public park in 1852.
Tollcross is an area north of the River Clyde in Glasgow and has a popular park, opened in 1897, which is famed for its international rose trials. It lies approximately a mile east of the neighbouring suburb of Parkhead, and just north of Braidfauld and south of Shettleston. Tollcross was incorporated into the City of Glasgow in 1912.
The Adelaide Botanic Garden is a 51-hectare (130-acre) public garden at the north-east corner of the Adelaide city centre, in the Adelaide Park Lands. It encompasses a fenced garden on North Terrace and behind it the Botanic Park. Work was begun on the site in 1855, with its official opening to the public on 4 October 1857.
The Château de Bagatelle in Paris is a small Neoclassical-style château with several French formal gardens, a rose garden and an orangerie. It is set on 59 acres of grounds in French landscape style within the Bois de Boulogne, which is located in the 16th arrondissement of Paris.
The Royal National Rose Society (RNRS) (1876–2017) was a specialist horticultural organization in the United Kingdom dedicated to the cultivation and appreciation of roses. Founded in 1876 as the "National Rose Society", it was the world's oldest plant society. It was a membership organisation, with members drawn from professional and amateur gardeners and horticultural businesses. Originally based in London, the rose society moved its headquarters to Chiswell Green, near St Albans, Hertfordshire in 1959, where it created the Royal National Rose Society Gardens. In 1965, the society changed its name to the "Royal National Rose Society" (RNRS). At the height of its popularity, the RNRS had 100,000 members and its gardens contained 30,000 rose shrubs. The organisation was dissolved in May, 2017 and the gardens were closed permanently.
The American Rose Center is a rose garden in Shreveport, Louisiana owned and operated by The American Rose Society. There are over 20,000 rose bushes of 100 varieties in 65 separate rose gardens on 118 acres of pine forests and woodlands.
The San Jose Municipal Rose Garden is a historic rose garden in San Jose, California, in the Rose Garden District. Founded in 1927, the garden is exclusively dedicated to roses and features more than 3,500 shrubs representing 189 rose varieties.

Ulmus 'Homestead' is an American hybrid elm cultivar raised by Alden Townsend of the United States National Arboretum at the Nursery Crops Laboratory in Delaware, Ohio. The cultivar arose from a 1970 crossing of the Siberian Elm Ulmus pumila with the hybrid N 215, the latter grown from seed sent in 1960 to the University of Wisconsin-Madison elm breeding team by Hans Heybroek of the De Dorschkamp Research Institute in the Netherlands. Tested in the US National Elm Trial coordinated by Colorado State University, 'Homestead' averaged a survival rate of 85% after 10 years in the US National Elm Trial. However, planting of the tree was not recommended, owing principally to its 'ugly' shape and susceptibility to Southwest injury. 'Homestead' was released to commerce without patent restrictions in 1984.
The Parc de la Tête d'or is a large urban park in Lyon, France, with an area of approximately 117 hectares. Located in the northern part of the 6th arrondissement, it features the Jardin botanique de Lyon, as well as a lake on which boating takes place during the summer months. Due to the relatively small number of other parks in Lyon, it receives a huge number of visitors over summer; it is a frequent destination for joggers and cyclists.
A rose garden or rosarium is a garden or park, often open to the public, used to present and grow various types of garden roses, and sometimes rose species. Designs vary tremendously and roses may be displayed alongside other plants or grouped by individual variety, colour or class in rose beds. Technically it is a specialized type of shrub garden, but normally treated as a type of flower garden, if only because its origins in Europe go back to at least the Middle Ages in Europe, when roses were effectively the largest and most popular flowers, already existing in numerous garden cultivars.
Auckland Botanic Gardens is a botanical garden in the New Zealand city of Auckland. It is located in the suburb of Manurewa, in the Manurewa Local Board Area. The garden covers 64 hectares, and holds more than 10,000 plants.
Garden roses are predominantly hybrid roses that are grown as ornamental plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. An enormous number of garden cultivars has been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, often in dedicated rose gardens, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging.
The Julia Child rose, known in the UK as the Absolutely Fabulous rose, is a golden butter or golden floribunda rose, named after the chef Julia Child.
A rose show is a horticultural exhibition focusing exclusively on roses.
The All-America Rose Selections (AARS) is an award that was given annually, from 1940 to 2013, by the American rose industry to an outstanding new rose variety. The AARS selection was regarded as the most prestigious rose prize in the United States for 73 years. AARS was discontinued after 2013, and was replaced in 2016 by the new American Garden Rose Selections (AGRS) program.
The American Garden Rose Selections (AGRS) is an annual award sponsored by the American rose industry to acknowledge and recommend outstanding rose varieties for different regions of the United States. AGRS replaced the long-established All-America Rose Selections, which was discontinued after 2012. AGRS's first annual award was introduced in 2016. The AGRS selection process involves rose trials in multiple regional test gardens throughout the U.S. Promising rose varieties are grown and evaluated multiple times a year for two years. Only 4% of all the roses tested in the program are selected for the AGRS award.
