Poisonous Plants -  A List for the Gardener/Flower Admirer
With the gorgeous spring weather starting, I know many of us (including myself) turn to
our gardens and flower beds with many ideas and great plans.  Unfortunately, there are
some plants that can be harmful or even fatal to our beloved pets and our neighbor's
outdoor animals.  With that in mind, we want to present a list of some common toxic
plants that can be found in the everyday garden or indoor bouquet (for those pets that
don't go outside).

The main alert for this list was regarding lilies.  Any flower of the genus Lilium will cause
potentially fatal kidney failure in cats.  
This can be from eating the plant itself, sniffing
the pollen off the plant, or even cleaning the pollen from a lily off their fur.
 Examples of
these are Tiger lilies, Easter lilies, Stargazers, and Oriental lilies.  Day lilies can also
cause kidney failure.  Other lilies, such as calla lilies or peace lilies, are not in the genus
Lilium.  They do not cause kidney failure, but can cause significant oral and
gastrointestinal irritation.
It is
VERY important that cats who have eaten lilies be seen immediately by a
veterinarian.  If they are seen within 18 hours of ingestion and treated aggressively, they
may not develop fatal kidney failure.  If left untreated, they will likely die.

I want to present the other plants in list form, so that its a little easier to look at quickly
if you have a worry about a specific plant/flower type.  Don't let this detract from filling
your garden or home with things you love, just be careful in your choices if you have pets
who like to eat these plants instead of looking at them!


The following is a partial list of plants that have been shown to cause more severe
toxicity in small animals.

Potentially Cardiotoxic (heart damage) Plants:
Lily of the Valley (Convallaria majalis)
Oleander (Nerium oleander)
Rhododendron species
Japanese, American, English, and Western Yew (Taxus species)
Foxglove (Digitalis purpurea)
Kalanchoe species
Kalmia species

Plants that could cause kidney failure:
Rhubarb (Rheum species)- leaves only
Lilies (Day lily also, Easter Lily, Asian Lily, Stargazer, etc..) - all parts of plants, cats only

Plants that could cause liver failure:
Cycad, Sago, Zamia Palm (Cycad species)
Amanita mushrooms

Plants that can cause multi-system effects:
Autumn Crocus (Colchicum species)
Castor Bean (Ricinus species)

Plants containing Calcium Oxalate Crystals:
Peace lilies (Spathiphyllum sp)
Calla lily (Zantedeschia aethiopiea)
Philodendron (Philodendron sp)
Dumb Cane ( Dieffenbachia sp)
Mother in Law plant (Monstera sp)
Pothos (Epipremnum sp)

All these plants contain insoluble calcium oxalate crystals.
These crystals can cause mechanical irritation of the oral cavity and tongue when plant
material is ingested. Clinical signs that are usually include regurgitation, oral pain,
dysphagia (trouble swallowing), and anorexia. The signs are rarely severe and usually
respond to supportive care.
