Washington Hawthorn is an attractive ornamental shrub that is dense enough to plant as a privacy screen. It produces clusters of white blooms in late spring to early summer.

Washington Hawthorn's red berries last throughout winter, bringing squirrels and birds to your property. In the fall, its foliage turns beautiful orange, scarlet, or purple.

One of the most overlooked trees on the prairies. This tree is often used as rootstock, a wildlife attractor, or a boulevard hedge. Give this one a second look.

This species is also known as one of the more salt-tolerant species for those with saline soils.

Please note: this plant is poisonous to dogs.

Black Crowberry is a native evergreen shrub that forms low, spreading mats. It has unique foliage that spirals around the stem, and small dark berries, giving it visual appeal. The berries are edible, but can be acidic, so they are not generally eaten fresh. In colder climates, the berries develop a sweet-tart flavor and are often dried or used in desserts, jams, and jellies.

This hardy shrub provides food for birds and mammals, while its flowers attract pollinators such as bees. It also serves as a host plant for certain butterflies and moths. Together, these roles make it a key contributor to the health of tundra and boreal ecosystems.

In Newfoundland and Labrador, the berries are known locally as ‘blackberries’ and are enjoyed in jams, jellies, and traditional baked goods such as buns and puddings. In Scandinavia, they continue to be used in liqueurs, wines, and juices.
