Annuals at The Ornamental Gardens

The city of Ottawa is considered "a city of gardens" with over 75 public gardens.[1] The Ornamental Gardens are located at Agriculture and Agri-Food Canada's Central Experimental Farm in Ottawa, Ontario, Canada. The 3.2 hectares (8 acres) were once used as a test facility for the development of winter hardy roses, weigela and peonies.[2] But now acts as the steward to several large collections of ornamentals.

To provide a proper environment for the many plant collections the Ornamental Gardens has been subdivided into several features. These include the Macoun Memorial Garden, the Lilac Walk, the Rock Garden, the Perennial Border, Arthur Percy Saunders peonies, Isabella Preston lilac series, and the Explorer Rose Garden. wereas display garden for the AAS (All American Selection) the Ornamental Gardens also presents a yearly, dynamic display of the choicest annuals and perennials.

History[edit]

The current site of the Central Experimental Farm was founded in 1886 from a site of near wilderness carved out by the First Farm director William Saunders.[3] At the age of 62, his passion for flowers along with newly appointed Horticulturalist William T. Macoun utilized his plans for the garden from 12-years prior to develop the forest to a modern example of the current ornamental gardens.[4]

There have been multiple phases to modern-day development of the property due to primary research, education and landscape.[5] These changes have undergone physical movements, redesigns, expansions, neglections, restorations, and rebuilds.[6] Recently federal employees and volunteers have restored the rose, peony, lilac and iris collections, in which were designed to honour the work of Ottawa's Isabella Preston and Felicitas Svejda.[7]

Geography[edit]

The Ornamental Gardens are currently one of five public areas associated with the Central Experimental farm.[8] These include the Dominion Arboretum, Tropical Greenhouses, Merivale Shelterbelt, Canada Agriculture and Food Museum.

Collections[edit]

The Ornamental Gardens is home to six primary collections. The lilacs, heritage roses, peonies, explorer roses, irises and daylilies, and perennials.

Lilacs[edit]

Amongst the first plantings on the Central Experimental Farm grounds were 15 lilacs, despite having been first introduced in the dominion Arboretum.[9] By 1919, the lilacs were moved into the ornamental gardens to create the lilac walks currently open for viewing with over 340 lilacs encompassing 262 variations.[10] In 1982, under presentation and cultivation of the lilacs, Agriculture and Agri-Food Canada was awarded from the International Lilac Society for its lilac cultivators and educating the public on the beauty and use of lilacs.[11]

Heritage Roses[edit]

Under William Saunders, the first roses were established in 1886, and by 1895 there was published list of “desirable” roses.[12] Years were spend testing and cultivating for perfectly formed varieties. Cultivation was led by rose breeders for over 90 years from supervision under William Saunders to Isabella Preston.[13]

Peonies[edit]

Currently, there are 12 garden bed with 350 peonies.[14]

Explorer Roses[edit]

Agriculture and Agri-Food Canada began a rose breeding program in the 1960s under Felicitas Svejda. This program would develop the Explorer series, that is a set of hardy roses variations developed to withstand the harsh Canadian climates, particularly with the ability to survive in -35 °C when snow-covered.[15] Svejda was successfully involved in the first thirteen cultivations, in which would be named after Canadian explorers in hopes of proving they were as 'tough and versatile as their namesakes'.[16] This would develop the Explorer Rose garden, as a Canadian-made collection and one of Agriculture and Agri-Food Canada's most impressive horticultural success stories.[17] The collection was officially opened in July 2005, and currently AAFC employees and a dedicated team of volunteers have combined the original collection from the original bushes with more recent varieties for improved displays.[18]

Irises and Daylilies[edit]

There are 15 separate garden beds that form concentric circles, with four corners squaring the pattern. In the inner circle and four corners there is presence of Siberian Irises, the middle circle contains Bearded Irises, while the outer circle contains Daylilies.[19]

Perennials[edit]

Perennials are hardy, herbaceous plants that can survive year around because of there underground organs that enter a state of dormancy during autumn months.[20] These plants are a value to sustainable agriculture, as the field of horticulture provides technologies to improve the yields of plant growth.[21] The ability for annual growth promotes weed control and improved soil health and biodiversity with the reduction in fertilizer usage.[22]

Mineral Chemistry[edit]

The horticulture industry is seeminglessly more than continuous growth and development of plants. Every chosen species in an environment has its own chemical composition. The ornamental gardens show presence of agrominerals, in which demonstrate mineral substance mixtures of mineral and organic substances. the dominant chemical composition facilitated in the garden is concentrations of nitrogen, carbon, potassium, and phosphorus.

Nitrogen[edit]

Nitrogen is an essential macronutrient for plants, that determines development and productivity through variations of abiotic stress responses.[23] Agriculture and Agri-Food Canada follows a continuous process, that begins with preparation in the Tropical Greenhouses at the Central Experimental Farm during the spring months. A series of annual plants undergo the pricking of seedlings and individually placed in garden pots containing Pro-Mix Potting Soil.

Pro-Mix Potting Soil[edit]

White appearance gives evidence of Nitrogen

Pro-Mix Potting Soil is a starter fertilizer that contains 7% total nitrogen to help plants acclimate to a new rooting system.[24] Nitrogen is fundamental mineral in soil for plant health, and is critical to its growth and reproduction.[25] Usage provides an increase in nutrient and water uptake because of the symbiotic relationship and stimulation of fungi that colonizes the root tissue.[26] This leads to a better integration of moisture management with an larger root system that causes an increased plant growth capacity.[27]

Phorsphorus[edit]

Substances work to correlate and interwine to intiate greater outcomes. Phorsphorus promotes nitrogen uptake by enchancing nitrogen retention in ecosystems.[28] While essential for cell division and development of growing plants. This allows plants to capture, store and convert sunlight energy to biochemicals like Adenosine Triphosphate (ATP).[29]

Potassium[edit]

Potassium is a vital macronutrient that increases root function and improve drought resistance.[30] The responsibility of vital plant enzymes activate and regulate the water balance and uptake while protecting and mitigating abiotic induced stresses to maintain homeostasis.[31] In practice, potassium is filtered through constant grass clippings in which provide the soil with nutrients that contribute to preventing weed growth while preserving moisture.[32]
