I guess mewolf has disappeared again, so..................
This is a common shrub/small tree and an invasive plant, at least up here.
This species can be distinguished from its other siblings by often having spines at the tips of the twigs.
(BTW, these are not my pictures).
The identifying features I look for are:
- opposite or nearly so, leaves
- leaf veins that curve towards the tip
- leaf margin is finely toothed
- usually is well laden with small black fruit, that remain well into the winter, making you wonder why the birds aren't eating them.(but apparently some birds and some mammals do eat them).
Other identifying features:
- will grow to 20-25 feet high
The fruit and bark are considered potentially toxic. The fresh bark or berries can be violently laxative and may irritate the skin or mucous membranes. It is used medicinally for its laxative qualities. Deaths in children from eating berries, have been reported.
I have found the bark, at least from the young shrubs, to be flammable, though not as much as Birch (Betula spp.) or Cherry (Prunus spp.)
Have fun!
