Garden areas have been created and planted based on particular criteria for each. Geographical Collections display plants from a certain region. Ecological Collections showcase plants that inhabit a particular type of ecosystem. Taxonomic Collections are based on plant classification and evolution. Theme Collections bring together plants based on their landscape or cultural uses.
These gardens are as hard-working as the Constructed Wetlands. They provide resources for courses and programs at the College, gardening information and inspiration for garden visitors, research opportunities, and of course a wonderful setting for campus staff.
Natural Area originated when Olds College staff were alerted to a construction project that involved the widening of Highway 2A and the resulting destruction and loss of natural habitats and plant species. Staff staged a ‘plant rescue’, digging up plants and bringing them back to campus. They were installed, creating a new garden area to showcase species native to the Central Parkland ecosystem in which Olds is situated.
The plants rescued were primarily herbaceous (perennial grasses and wildflowers) and include plants more suited to upland areas such as native asters, bluebells (Campanula spp.), Canada anemone (Anemone canadensis) as well as those more comfortable with a moister setting including coltsfoot (Petasites spp.) and rushes (Scirpus spp., Juncus spp.). Woody plants were added later and can now be found well established in this site, including native rose (Rosa spp.), wolfwillow (Elaeagnus commutata), alder (Alnus spp.), river birch (Betula occidentalis) and trembling aspen (Populus tremuloides). This portion of the Botanic Garden provides an interesting contrast with the more formal parts of the garden. Visitors may leave with an idea for a native plant that would be appropriate for their own setting.
Alpine plants are well adapted to their conditions. They often grow very long roots to obtain the necessary moisture and nutrients. Foliage may have a protective covering such as a waxy coating or long hairs for protection against the environment. The plants produce an abundance of soluble sugars which will lower the freezing point of the plant’s cells. Many alpines grow in tufts or communities to provide insulation. The Alpine Garden displays alpine plants, many of which can be grown in prairie gardens. Some of the plants found in this garden include species of primulas, clematis, gentians, phlox, Draba, Androsace and many others.
Water gardens offer a display of textures, forms, and colours and provide many benefits. Moving water captures the visitor’s attention, and any water will act as an attractant to local wildlife including reptiles and amphibians, birds and insect life. A small stream wanders south, and along its edge can be found wonderful examples of creeping willow (Salix repens) that have created mounds along the upper edge of each side, reaching branches down towards the water. Plants were supplied by Bearberry Creek Water Gardens, a local nursery specializing in water plants.
