Safety & Hazards
All parts of the plant, except the flesh of the fruit (actually an aril), are potentially highly poisonous. They contain the alkaloid taxine and , if ingested, can cause nervousness, trembling, slow pulse, pupil dilation, difficult breathing, abdominal pain, vomiting, diarrhoea, weakness and convulsions - in larger doses it can be fatal, having a paralyzing affect on the heart[ 1 Title RHS Dictionary of Plants plus Supplement. 1956 Publication Author F.

Botanical Description
Taxus canadensis is usually a shrub of spreading habit, often low and straggling; it can grow 120 - 180cm tall[ 11 Title Trees and Shrubs Hardy in Great Britain. Vol 1 - 4 and Supplement. Publication Author Bean. W. Publisher Murray Year 1981 ISBN - Description A classic with a wealth of information on the plants, but poor on pictures. ]. The plant is harvested from the wild for local use as a food and a medicine. It is sometimes grown as an ornamental. Taxus canadensis has an extensive range in northeastern North America. Although it has undergone a decline within that range over the last century, especially in the south, the extent of decline is currently insufficient for it to qualify for listing under any threatened category. The decline is expected to continue and may increase if predicted climate change impacts such as reduced snow cover lead to an increase in browsing pressures, the primary threat. A reassessment within the next ten years will be necessary. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ].
