Beaked hazel, Corylus cornuta.

Although a shrub, the beaked hazel (Corylus cornuta) is a member of the birch family. Male and female flowers are separate, but are on the same bush. This is a female flower, which is much smaller and more colourful than the male. The fruits ripen into edible nuts (hazelnuts) in autumn. For centuries, native peoples used the wood to make arrows, and in some areas the buds and roots were used to make a blue dye. In Canada, the plant is found in moist woods and thickets from British Columbia to Newfoundland and Labrador.
