Prairie Gardens

Staff and volunteers have worked hard over the years to create and maintain garden spaces around the schoolhouse and featuring indigenous species of grasses and flowers. Take the time to explore the grounds and brush up on your plant ID skills before going into the Park. Below is a sampling of what you might see.

Buttercup family

Canada anemone

Anemonastrum canadense

Also known as: crowfoot, meadow anemone, round-leaf thimbleweed, windflower

The Canada anemone is found throughout the Prairie Provinces in large patches at the edges of woodlands, in low moist areas, and in hollows. The plant stands 30cm high and with a hairy stem. White flowers are found at the end of a bract.

The plant, generally poisonous, may be used to aid with bruises and sore muscles, as its mashed leaves serve as a counter-irritant when used in small amounts.

Prairie crocus

Pulsatilla nuttaliana

Also known as: common pasqueflower, cutleaf anemone

Often the first flower to bloom in the spring, crocuses grow between 8-12cm tall. The leaves and stem are covered in a white fuzz which helps protect the plant from cool weather. The flower is typically a light purple with a bright yellow stamen.

Like other pasque flowers, the prairie crocus is poisonous when consumed and irritant when contacted. Still, some First Nations used crushed crocus leaves as a counter-irritant, similarly to the Canada anemone. This species is the provincial flower of Manitoba.

Cactus family

Pincushion cactus

Escobaria vivipara

Also known as: ball cactus, bell cactus, cushion cactus, spinystar, viviparous foxtail cactus

This tall perennial shrub has brownish-yellow flowers that appear in May-June. The bright red berry is harvested and used to make jelly.

The buffaloberry has found many uses as a medicine—such as to treat flu and indigestion—and especially as a food. The Blackfoot (Siksikaitsitapi), for example, have eaten buffaloberries fresh in summer and dried in winter, preserving them in jellies or cooked with sugar to make pudding.

Wolf willow

Elaeagnus commutata

Also known as: silverberry

This perennial low growing shrub blooms in June with tiny fragrant blossoms. Produces a silvery mealy berry containing a large seed. Grows in the moisture draws of the prairie.

As the wolf willow’s berry is dry and dispreferred, its berries are often overlooked (except in times of famine) in favour of its bark, which has been used as a medicine, such as to take away the sting of a frostbite or a sunburn.

Plantain family
