This specimen is the silver fruit of the wolf-willow (silverberry; Elaeagnus commutata). What appears to be the stem of the fruit, is actually the persistent corolla (petals) of the flower. Combined, it is only 14mm long.
Wolf-willow is a shrub, with yellow and silvery flowers that have a sweet smell detectable a ways from the plant. It is also known as silverberry for its distinct silvery leaves and fruits. This shrub is widespread and is locally visible along the open slopes of the Edmonton river valley and in city parks.
The fruit is edible, rich in vitamins, fat, and protein, and can be eaten raw, cooked or mixed with fat (Kuhnlein & Turner 1991). Although the fruit resembles a berry, it is classified as a dry mealy drupe. Peaches, cherries, and plums are all a type of drupe. This plant is also used in reclamation projects to improve soil and erosion control.
