POISONOUS AND NON-POISONOUS PLANTS. Many popular house
and garden plants are considered poisonous and can produce symptoms ranging from
minor to severe. Table A-1 provides a non-comprehensive list of common plants that
are known to be poisonous. Table A-2 provides a list of plants for which no evidence
currently exists of a poisonous quality. These lists are provided by the Maryland Poison
Center. Within the United States, check with local extensions of the US Department of
Agriculture for more information about the nature of common plantings in specific
locations. These lists are not intended to serve as a guide for plants to use or not use
but are merely provided for informational purposes. See Section 3-6 for more
information on landscaping and plant selection. Refer to a comprehensive, commercial
field guide for a complete lists of poisonous plants. Additional information can also be
