Known As:  Cabinet-Cherry, Black Choke, Rum Cherry, Virginian Prune-Bark, Whisky-Cherry, Wild Cherry, Wild Black Cherry.
Latin Name: Prunus serotina
Description: Can grow as a tree or a shrub up to 90 feet high.  Bark on young branches and twigs is scaly and reddish-brown with prominent cross-marks; bark on older branches and straight trunk is rough and black.  Leathery leaves are alternate, simple, elliptic-pointed and finely toothed on the edges.  Showy, fragrant white flowers hang in drooping clusters and produce dark-red to purply-black cherry fruit about the size of a pea.
Poisonous Parts:  All parts are potentially toxic but damaged leaves are the greatest risk.  Contains prunasin which is a cyogenic precursor that releases cyanide when damaged.
Symptoms: Anxiety, breathing problems, staggering, collapse, sudden death. May produce vomiting, abdominal pain, and in some cases diarrhea.
Treatment: Contact a veterinarian and rush your pet to them immediately.  Antidote needs to be given intravenously within a few minutes of the onset of the signs.  Do not handle or stress affected animals more than necessary as this will worsen the signs.
