The Autumn Olive and its relative, the Russian Olive (Elaeagnus angustifolia)
are deciduous shrubs/small trees with smooth gray bark. They have distinctive silvery
scales/dots on the young stems, leaves, flowers and fruits. The backs of the leaves
are an especially distinctive, somewhat translucent silver color. (See picture to the
right.) The leaves are alternate and slightly oval to lanceolate. They have untoothed
(entire) margins.
The front of the Autumn Olive leaves are a dull green color, but
are reported to become brighter green towards the Fall as some of the coloration rubs off.
On the other hand, the front of the Russian Olive leaves are a gray-green color and stay
like that all season. The Russian Olive leaves tend to be much thinner (more willow-like
according to Samuel Thayer)
and have a silvery sheen on both sides of the leaf.
The flowers (not shown) are light yellow and appear in May. The
fruit of Autumn Olive is a pink to red color with silver dots while the fruit of
Russian Olive is yellow or orange with silver dots. It is available for harvest in
late August through October. It is high in lycopene. I find the fruit of
the Russian Olive sweeter than that of the Autumn Olive, but the Russian Olive is
much more rare in Southeastern, New Hampshire.
