The Ornamental Gardens are bordered by Prince of Wales Drive to the South-East, National Capital Commission Scenic Driveway to the North-West, and the Research Fields to the South-West.

William Saunders was appointed the first Farm director, and at the age of 62 in October 1886, he paved the way to carve out 20 acres of field, with visions for the future amongst his passion for flowers.

On September 9, 1922, she was made a permanent specialist in ornamental horticulture where she would cultivate new plants for Canadian gardens and building an international reputation for the Central Experimental Farm.

[4] Recently AAFC Staff 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.

[14] Svejda was successfully involved in the first thirteen cultivars, in which would be named after Canadian explorers in hopes of proving they were as 'tough and versatile as their namesakes'.

[14] 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.

[6] Perennials are hardy, herbaceous plants that can survive year around because of there underground organs that enter a state of dormancy during autumn months.

[18] The ability for annual growth promotes weed control and improved soil health and biodiversity with the reduction in fertilizer usage.

The dominant chemical composition facilitated in the garden is concentrations of three vital macronutrients for plant growth, consisting of nitrogen, potassium, and phosphorus.

[20] 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.

[22] Usage provides an increase in nutrient and water uptake because of the symbiotic relationship and stimulation of fungi that colonizes the root tissue.

[26] In essence the clover supplies carbohydrates to the root nodules and used to convert atmospheric nitrogen into a form utilized by a plant to benefit grasses through transfer in soil.

[28] In which makes up 0.2% of a plant's dry weight, with essential components of nucleic acids, phospholipids, and adenosine triphosphate (ATP) to present a reliable supply to control key enzyme reactions and regulation of metabolic pathways.

[32] Potassium is relatively abundant in the earth's crust making up approximately 2.1% of the weight and is mined in the form of potash, sylvite, carnallite, and langbeinite.

[34] Plant survival with potassium usage has a responsibility of vital enzymes activating and regulating the water balance and uptake while protecting and mitigating abiotic induced stresses to maintain homeostasis.

[33] Potassium uptake is dependent on adenosine triphosphate (ATP) as it provides energy for chemical and physiological processes while facilitating protein and starch synthesis in plants.
