Oregon Grape

Blue Honeysuckle (wild Haskap or Honeyberry) is a cold hardy shrub and native to most of Canada. The pale yellow to white flowers provide nectar and pollen for bumblebees and other pollinators. The edible berries resemble elongated blueberries. They have a sweet-tart flavour often described as a blend of blueberry, raspberry, and blackcurrant, though wild berries can vary in taste.

Compared to popular cultivated varieties, the berries of Blue Honeysuckle are typically smaller and more variable in shape and flavour. While some enjoy eating the berries fresh, they are more commonly used in baking and preserves. Blue Honeysuckle can be used in hedgerows, border plantings, and naturalized landscapes. It may also serve as a cross-pollination partner in haskap plantings or as a decoy planting to draw birds and wildlife away from more desirable fruit crops.

Blue Honeysuckle has limited self-pollination and produces better yields when planted with other haskap plants or varieties for cross-pollination. Wild populations have not been studied as extensively as cultivated varieties, and because these plants are grown from seed, bloom timing and cross-pollination compatibility may vary.

Oregon Grape is an evergreen shrub native to North America, found along the Pacific coast. In spring, the bright golden-yellow flowers appear in clusters above the leaves. These flowers eventually give way to edible blue berries in late summer. While not a true grape, the berries appear grape-like due to their colouring and clustered growth. They can be eaten fresh, but the sour taste and high amounts of natural pectin make them well suited for preserves.

The Oregon Grape has leaves that are glossy, leathery, and spiny-edged. This feature gives it its alternate name of Holly-leaved Barberry. When the leaves emerge in the spring they are a bronze-red colour. In the summer they transition to green, followed by bright red to deep burgundy in the fall. Leaves are retained throughout the winter and colder temperatures cause the leaves to turn purplish bronze, providing year round interest to the landscape.
